Help. how do I select DS driving mode?

[DredM56]

Who said anything about power increase? I'm referring to the same throttle sensitivity and transmission performance. The G clearly has that stuff change between modes while the M does not.

Regardless, on the M (which we all drive) it's virtually mute and we're arguing semantics. Moving along...

You did.

"The M56x in Standard behaves almost ENTIRELY the same as the M56x in Sport. The only difference is that you get downshift assistance in aggressive driving (such as back roads). There is no discernible 'extra power' on take off, shifts don't seem any different, etc. Just the rev-matching feature, if you will. There is no major or discernible shift in the cars character, IMO."

For me there is a difference throttle is more sensitive it will engine brake and will hold the rpms for a bit longer if you get on it and then off it won't up shift right away so you can stab it again. That being said it isn't as aggressive as the G but again two different drivetrains with totally different characteristics. The G is like a Honda engine and the M is more like a Domestic V8. You obviously wouldn't program the transmission the same for both engines.Also the M is meant to be a premium luxury car. The G would hold the RPMs at 4-5k for too long that your average person would tolerate or even think was safe or proper in anyway.Fine for me but the average person buying a M brand new is 45+ and aren't looking for that.

On a side note after the recall work and transmission software update car is like a different vehicle.I stood on it from a stop sign taking a left and it got totally sideways and would of came right around if i didn't let off.

[reggiebrown40]

Perhaps my point was not understood?

The M56x in Standard behaves almost ENTIRELY the same as the M56x in Sport.

Ilya, it's possible that your UpRev tune has changed your M. But there is DEFINITELY a difference between sport and standard. Standard you have to press the pedal hard to get the car to respond. Sport -- the power is instant and extremely jerky if you don't know how to handle it. I definitely can tell the difference when I'm in sport vs. standard.

You're reading FAR too much into what I said. I, in no way, said that in sport mode there should be the expectation of more power. All I said was there wasn't and thus the two modes, as far as power delivery went, are identical.......which is TRUE (for my car at least). I in no way suggested that in standard mode, the car is running at 400hp (example) and in sport it's running at 420hp (example), etc...so...not sure how you misconstrued my comment to suggest that but that's on you. All I simply said was that, in my UpRev'ed '11, there is virtually zero difference between sport and standard. Now, between sport/standard and ECO or SNOW? Yeah, definitely a difference. If I'm cruising at 50mph and turn SNOW mode on, the car definitely changes it characteristic and the RPM's change, etc. ECO = the gas pedal has more resistance to it, etc.

Now...if your saying that this (below) is the case...it MAY be, but who knows.

All I know is that, in my application (unlike the many G's I've driven)...Sport vs Standard is utterly useless. My mistake was assuming that all M56's were like mine...which may or may not be the case.

Perhaps your butt dyno is more sensitive than mine?

[jmissile]

Im trying to understand how the gs feel more "agressive" between mode changes. There's a tremendous difference between standard and sport in my M but i have the AWS as well and its only 2wd. AWS in standard feels like it's not very active at all in the cornering department unlike sport mode, where the steering becomes very tight and twitchy to me, and I'm on the factory sport 20's with stock tires.
Granted there's absolutely no power/acceleration difference between sport and standard just the quicker throttle response, there's quite a few things that ARE enhanced in Sport mode besides that.
The steering and handling improve, standard to me feels like a non sport M with higher steering ratio and softer shifts. The AWS in sport kicks in big time when going through a curve at speed to minimize understeer where in standard I have to turn the wheel noticeably further to negotiate the same curve
The engine breaking in standard only slows you down for a couple seconds and then seems to coast in N where as in sport the engine braking feels stronger to me and seems to be slowing the car down more effectively. This is probably more noticeable in a v8 M than a v6 one. Also when I downshift manually in sport mode it blips the engine to a higher rpm than in standard mode causing the car to decelerate more quickly as well as maybe brake later upon entering corners. In standard it doesn't downshift automatically to 3rd when you break quickly like it does in sport, plus it def holds the gears longer too in sport/auto. Dredm56 mentioned that they obviously didn't program the v8 transmission like the v6 since its meant to be a premium luxury car but I have to disagree, the way DS felt in my car the few times i drove it that way was almost exactly the sort of behaviour you get when you put a v6 car in DS/auto, g's, m's, and q's. I've driven g37s and the q70 v6 and the DS /auto mode felt almost identical regarding how the transmission acted. You say it was meant to be a "premium luxury" car but the word performance should preface that description as well. They obviously wouldn't program the trannys the same for both engines but dam,it's def a car infiniti is obviously trying to use to challenge Bmw, Audi, Mercedes, in the performance sedan arena and so why wouldn't they give the M an agressive transmission program as the v6s do in sport versus standard if not giving the m56s an even more agressive transmission program than the v6's already have. But at the same time if DS was a mode they intended the m56 to have I'm sure it would've been much easier to turn on in the first place lol. I still feel that DS/auto mode is exactly what this car is missing and I'm still secretly hoping it's not a glitch and we'll find someone that can hack the car somehow so we all can enjoy it lol but dam if u ever get the pleasure of seein DS on your dash you'll know exactly what I'm sayin about what a beautiful combination this v8 with DS/auto is, and that was without responsive paddles/shifter lol...

Perhaps your butt dyno is more sensitive than mine?

Or perhaps you've modified your car to where sport and standard no longer have a discernible difference between the two modes. There's no butt dyno involved -- there's a legit difference between the two modes.

Was responding to Dred (butt dyno comment) while acknowledging your post (regarding upgrades making my cars modes 'static' and unchanging). It certainly is a possibility because I definitely don't get the sensation of change that any of you guys are talking about.

[reggiebrown40]

I was just responding to the butt dyno comment and didn't assume it was intended for anyone specific. Anyone with stock programming will tell you that sport is more responsive than normal.

[Ilya]

I'll have to go back to my stock map and test this out next time I'm in the car.

[Ilya]

I'll have to go back to my stock map and test this out next time I'm in the car.

I had to run to the post office so I did a test.

With my ECU still flashed as UpRev, I switched to my stock tune (map #1)...

Did a couple of 20-90 WOT pulls. Car behaves the same in Standard as it does in Sport. Literally no difference in shift points, shift feel, etc. I was in regular mode (not M/manual so I let the car do everything on it's own). Both modes shift gears at the same RPM (around 6400 RPM at quick glance).

The ONLY thing noticed was the downshift assistance/rev matching in sport. That's it. Absolutely zero change in pedal feedback, steering feel, shifting, etc.

Would be curious to see if I completely removed UpRev and reflashed to full stock ECU what the result would be...

[ArmedAviator]

Anyone with stock programming will tell you that sport is more responsive than normal.

I concur with this statement.

In Sport mode, the throttle is quicker to respond/aggressive and the transmission delays shifting if I drive it like a sports sedan. If I drive like a grandma, both modes feel the same.

I'm reading exactly what you said lol. You talked about the G growing a pair and that there is no discernible extra power on take off. How is that supposed to be taken other than that you think the car is faster from a dig in sport mode.When someone says they don't notice extra power I assume they mean what they say and were expecting extra power or something that somehow feels like extra power but isn't.

I've done multiple timed tests at the dragstrip with legit timing gear that shows its not the case period and there is zero debate about it. I made over a 100 passes in the G and have the fastest stock X time with solid proof to back it up. I'll be looking to do the same with the M .Trust me if there was a secret to get it go faster I'd be all over it.

Also your test of flooring it and letting it shift really tests nothing. The G also goes to the same shift point when floored in drive or in sport mode. I don't know what you guys are expecting it to do. Unless a car is boosted and or has adjustable suspension or an electric diff or DCT how much change can they really do unless they purposely hold the car back in normal mode.

But what you guys that worship the DS god are saying is the Sport mode they let you access on the dial actually does nothing. But some weird sequence you do to get DS to pop up that isn't repeatable is what actually changes the car. Now does that make any sense.

What Reggie Brown says may be true. I'm not sure exactly what maps are accessible through UPrev I've never used it or looked at their software before. It's possible they tuned the throttle sensitivity so that you now see no difference because they already have it set to the sensitivity of Sport mode.

** IN MY OPINION AKA UNSCIENTIFIC **

G DOES behave much sportier when put into DS/Sport mode...shifts are CLEARLY better. This gives the sensation of more power/balls.

M DOES NOT behave much sportier when put into Sport mode...shifts are CLEARLY the same. This does not give the sensation of more power/balls...aka no discernible difference. There IS a discernible difference in the character of the car when I put it in SNOW or ECO mode (SNOW mode = RPM changes, car seems to 'lug' a tiny bit due to I'm guessing both diffs doing whatever it is that AWD does when sharing power, etc...same for ECO mode = pedal resistance, etc.).

So, no, you're still reading into what I said and not getting what I meant. Which is fine...I guess.

I'm using whatever unscientific method I have at my disposal which happens to be a road with cornfields on both sides that is about as long as a drag strip.

My thinking was that, if in fact sport/standard on MY M were different (which in my car they aren't - see your/Reggies comments about UpRev possibly overriding the setting which is a DEFINITE possibility), I would have a lower shift point at WOT in standard (where perhaps it's trying to maximize EPA efficiency like in the ECO mode) than in sport mode where I would expect an absolute maximum shift point to get the most out of the gear. That was the only point of that WOT test.

Again, I don't have the timing equipment you have, etc...nor do I care to have it. My tests are unscientific...but you're clearly not getting what I'm saying and I'm done beating this dead horse. Carry on folks...I'm out.

[jmissile]

I will be continuing to investigate this to see if I can get to the bottom of this. I'm still not giving up, because just like I notice a big difference between standard and sport mode in my car, I also noticed a significant difference when my car was running in DS. It's such a significant difference I don't need any scan tool, computer, butt dyno to confirm this for me.Doesnt matter if it wasnt intentionally accessable by infinity, or if its a glitch, but I'm aware of exactly how my car behaves in all of the modes and until youve felt how DS feels in this car for yourself u cant tell me there's no difference.Just maybe there's is a way to access DS on our cars by rearranging the wires going into the connector for the mode switch. I need to find one of these breakdowns on the g37 on the drive mode selector to see I can figure out how they have this DSmode and Ms do not. Kinda daunting but who knows,I might have a faulty switch or something, maybe one of you guys (DS mode worshippers only LOL)can understand how this thing actually work, doesn't seem too complicated to me, but I can say with all certainty that infiniti is claiming the car IS "held back"in SNOW and ECO, and that engine output characteristics in sport mode are INCREASED which I know doesn't increase horsepower but there are a number of things according to this if you read it that do actually change or are engaged in sport mode that u dont have in the other modes.https://www.google.com/url?sa=t&source= ...

[reggiebrown40]

Ilya, I think the problem here is that you're comparing your modified ECU to a stock one. I think based on what you're saying 2 things are true: a) your upRev tune has 2 settings that are identical (sport and normal) and b) your stock map #1 is identical to your upRev tune. Maybe your tech didn't save the settings properly. You can only say one thing definitively: YOUR car does not have a discernible difference between the sport and normal modes. But you are wrong when you say "THE M" (meaning all M37/M56's ever produced) has no difference between sport and normal mode. I would like to say that there is no one else here that would agree that sport and normal are identical, but I've learned on this forum that it's best to just speak for yourself.....

[Ilya]

lol...not letting go, eh? Okay, I'll bite. I've stated from the beginning that my thoughts pertain to my car with quotes (unedited from their originality) such as:

Sport mode on the M isn't that much different than the regular mode...at least on my M56.

The M56x in Standard behaves almost ENTIRELY the same as the M56x in Sport. -- I guess this can be misconstrued as me making a blanket statement but in the same post further down I state that I'm referring to my M --

On the M (at least the M56x I have with UpRev and HPS intake hoses)...

All I simply said was that, in my UpRev'ed '11, there is virtually zero difference between sport and standard. Now, between sport/standard and ECO or SNOW? Yeah, definitely a difference.

** IN MY OPINION AKA UNSCIENTIFIC ** -- referring to my experiences with both cars thus only referring to MY M --

G DOES behave much sportier when put into DS/Sport mode...shifts are CLEARLY better. This gives the sensation of more power/balls.

M DOES NOT behave much sportier when put into Sport mode...shifts are CLEARLY the same...

My thinking was that, if in fact sport/standard on MY M were different...

I did say this after a few posts in this thread of me talking about my specific car after getting annoyed and thus :

Who said anything about power increase? I'm referring to the same throttle sensitivity and transmission performance. The G clearly has that stuff change between modes while the M does not. -- referring to the ones I've driven as loaners and mine based on my personal experience --

Regardless, on the M (which we all drive) it's virtually mute and we're arguing semantics. Moving along... -- this is the gotcha that you guys evidently are letting override all of my other posts in this thread --

I made one post out of like 8 in this thread that was for sure a blanket statement (whoa! My bad! Stop the presses!) and people are arguing with me over it lol. In all but one of my posts, I have been referring to my specific car and have been clear about that.

Bottom line is, without proving out the UpRev theory by removing UpRev...we simply don't know if UpRev is at fault for my experience or if it's my M in general...for all we know it's not UpRev and my earlier blanket statement is more valid than initially thought. Unfortunately, this M community is small and we don't represent all M's in the world...so even if YOU guys say that 5 cars in here exhibit change (thus, as an example, making blanket statements such as "UpRev is the difference in your car") or I say that 1 car does not exhibit change (thus, as an example, ME saying "UpRev isn't the difference in my car")...neither one of us can say that with 100% certainty until a UpRev vs Non-UpRev test can be performed on the SAME car (whether mine or someone else's). Everyone is making blanket statements otherwise. Perhaps I will take the time to unflash UpRev and go back to 100% stock.

Also, Seymore64 (who's tuned many cars) is a good UpRev tuner and many members here have been tuned by him so it's not an issue of the tuner leaving settings, etc. Guy knows these cars.

Here is the layout of MY maps (users can have any 5 maps they want):

#1 - Stock OEM Map
#2 - Performance Map
#3 - ECO Map
#4 - Valet Mode (25mph max/3krpm max - can be configured)
#5 - Anti-Theft (car won't start and if switched to this map while car is running the car will die after sputtering for 3-4 seconds)

Now...is it possible that the maps only relate to AFR and thus the #1 map isn't any different in terms of shifting, etc.? Sure. Is it possible that UpRev overrides every mode as far as timing advance, etc. thus getting most modes on a 'level' field? Sure. But I don't have that information for you.

So thus, as I've said before, "in my application" there is no difference. Whether that's UpRev or just the way my car is...beats me. Perhaps one day soon I'll remove UpRev and find out.

Carry on with the debate of DS being a glitch or not........................................

[reggiebrown40]

It was more than one post that you said the M was the same in sport and normal mode. If you get annoyed about a discussion regarding sport and normal mode, then lol @ you.

[Ilya]

It was more than one post that you said the M was the same in sport and normal mode. If you get annoyed about a discussion regarding sport and normal mode, then lol @ you.

Yes, I listed them all above (as I went through every post). And in all but one, I was referring to my M. Way to catch me on one post, rather, one line in one post. Don't break your arm trying to pat yourself on the back .

And yes, I get annoyed with people arguing semantics over one line in one post when all other posts were explicit in what I was talking about (my vehicle). And here we are...after like 5 posts just between you and I, at the same spot we started (remember that horse? It's quite bloody now...)...why don't you post again so we can continue this charade?

[reggiebrown40]

This is my last post, I promise.

You shouldn't be an admin if you get annoyed so easily.

[Ilya]

You shouldn't be an admin if you get annoyed so easily.

Well, perhaps when you do the following you can take over for me:

• invest hundreds of hours and years of time into this forum and the Y50 forum in organizing them and cleaning them up
• are willing to answer any and all threads to try and help users feel welcome (especially if it's their first post) and get them the info they came here for
• pointing them to certain topics when they fail to use the search button over and over and over and over again
• log in 50x a day
• take the time to create threads like the FAQ threads and curate all the information on these forums for ease of use/finding for our members (and even Google searching non-members)
• help users by writing HowTo's
• etc

Until then:



=================

Anyway...to wrap up the saga that is "Ilya vs Y51 NICO Members regarding Sport vs Standard drive mode"...

For S&G's I took the time to compare UpRev vs non-UpRev today by driving with UpRev, flashing to full stock and driving, and then going back to UpRev.

The car, as I said before, behaves almost identically regardless of ECU programming or map. The only thing, evidently, that UpRev touches is AFR (at least in my tunes). Nothing else is affected. So, today, we have confirmed that UpRev did NOT change my car or override any settings.

In both cases (UpRev vs Stock), the only thing I noticed while driving aggressively (no straight line WOT runs this time...actually went out on the back roads where there is a lot of twisties and pushed the car hard to the point where I've confirmed my rotor(s) are warped )...is that the car would downshift/rev match if I got onto the brakes hard enough going into a corner and would hold that gear through the corner if I stayed on the throttle. But that didn't happen on all corners. Only those where you brake x% when approaching (whatever that value may be). Nothing else. Steering didn't get tighter, gear shifts didn't get crisper/faster, shift points didn't change, car didn't give the sensation of being any faster, etc. You go just as fast in standard mode if you push the pedal hard enough and the feel of the transmission (how long it takes to change gears, etc.) is identical. Again, I don't know what people expect sport/DS to give them as far as performance boost, but I notice only the downshifting. This isn't an Aston Martin or a Ferrari where if you go into sport mode the car lowers itself an inch, suspension firms up, more power is unlocked, etc. etc. etc. It's an Infiniti which is largely static in it's performance.

That being said, I stand by my earlier comments. In day to day driving around town or straight line speeding (such as highway), sport mode = standard mode for all intents and purposes on my 2011 Infiniti M56x. You have to really get on the car in the twisties/exit ramps, in sport mode, to notice the rev matching/downshifting ability of sport mode.

Again...to reiterate for those who like to pick at words and argue semantics....THIS IS ONLY ON MY M!

So that being said...for those of you who swear that standard and sport = day and night difference on an Infiniti M/Q...I honestly have no idea what to tell you. It's so negligible it's hardly noticeable on my car...you'd have to live on a F1 track and have the last name Schumacher to get real use of the sport mode in my car.

Carry on chaps.

[ArmedAviator]

lol...not sure what else you'd need to change especially considering I don't have any crazy mods other than the HPS tubes and in the future the R2C intake.

[ArmedAviator]

In years past when I got ECU tunes, everything was adjustable....
AFR
Spark
Radiator fan cutoff temperatures
Shift points
Shift line pressure (faster/firmer shifts)
And so on....

Mind you, I do believe that these cars have everything set pretty damn well. But for the going rate of UpRev..... I'd expect alot more than an AFR tweak. Atleast spark table and shift pressure increase in "sport" mode or all modes.

[Ilya]

I believe shift line pressure and spark can be changed. Not sure about radiator fan tweaks. UpRev sees like 50 different sensors when plugged in and I think it can tweak anything it sees. I know there was a member here (forget his username) who was tweaking stuff having to do with the transmission...I wanna say it was adeedpb but I may be wrong. He or Seymore might be able to provide more info on what exactly UpRev is capable of doing...as far as I know it can be quite intensive...just not in my applications since my car is relatively stock.

Anyway...let's keep this topic to the DS glitch.

[DKASM37]

Just to chime in, Uprev doesn't change shift points but can modify those other items that were mentioned.

Carry on chaps.

Cheer up bro that's all it's supposed to do and that's all it does on the G I was trying to assure you you're not getting cheated somehow.It has zero effect on either car at full throttle. I certainly don't call it a night and day change. The G is more aggressive noticeable whatever in that it seems like it almost always a gear lower than it would normally be unless you are really babying it and engine brakes with lower brake force. The G engine braked in normal mode too though.The M doesn't seem too.
The only effect on the throttle is lets say .5" movement of the pedal equals 10% throttle in normal that same .5" is 15% in Sport. Obviously made up numbers.

Be happy that the manual mode is so much nicer on the M it's useless on the G for anything other than downshifting. They figured it out on the Q50 it feels crisp.

Here's a real world test with numbers coming up an exit ramp in sport mode at like 40 then floor it up to 70 let off the gas it holds the gear coasting down to 52 then upshifts slows down to 48 then drops rpms into coast gear. In normal mode it upshifts as soon as you let off then goes down very soon after to coast.

Then going up a hill at steady throttle pressure at 2800rpm in sport mode the instant I switch it to normal mode it upshifts . These are the types of things to expect from sport mode.

Wasn't you that said it was night and day...but I believe someone else did comment that it's a drastic change. I think you and I were saying similar things just in different ways.

OP, did you find the glitch yet?

Havent found it yet, probably a small electrical issue with the shifter (contacts?) unless there's a mechanical thing going on between it and the transmission

Just to chime in during my search and test drive of two m37s non-sport both 2013's and a 2015 q70s all v6's. One was m37x and the other m37. The m37x was quick but heavy which made the RWD m37 faster and more fun to drive imo. The difference between normal and sport mode was a visual difference in the RPM tach meter bumping up in sport mode. It made the car respond better when needing to get into passenger gear mode to pass. Not sure if it was a difference in power. I didn't get on the q70s but it drove better than both of the m37's. I ended up buying a M56s so just waiting on the transport company to drop it off so I can check it out. The m37 was fast so I can only imagine how much faster and stronger that V8 is. If it is anywhere near the speed and power of the 2007 Charger Srt8 I test drove a few years ago that is scary.
