M45 UpRev Tuning - Dyno Numbers?

[M4point5]

Just wanting to see what kind of numbers everyone has put down on their M45...or even M35. I got Osiris tune at a shop and gained 10hp over baseline with intake and exhaust. I was pretty disappointed in that. I am going to be using a different tuner in the next couple of weeks

[svard75]

Wait a sec, so you already had the intake and exhaust for the pre dyno and the uprev gave you 10hp at the wheels?! That's amazing!!! I would be happy with those numbers. I got about the same with a plenum spacer, ported and polished lower plenum, and z tube with the uprev. Likely somewhere around 2-3 hp gain from the tune on my AWD. The tuner feels my car is somewhere around 215hp at the wheels. Unfortunately I just had a dyno less tune since he only had the 2wd dyno. 10hp at the wheels is fantastic gains for a na engine.

[M4point5]

You have to understand also you have a V6, I have a V8. Maybe I am just used to my Evo X...a few simple mods and tuning netted 60hp and I didnt have to pay an outrageous $750 (erm...Osiris) for a tune. Say if I gained 25ho, I could justify 750 bucks.

Never got a base line before intake and exhaust but the baseline with intake and exhaust was 250-something...after tune 260-something at the wheels. It was a 12 or 13hp gain, I will have to check the dyno sheet. Those numbers are nothing these days...4cyl are almost making that out of the factory, and surely V6's if not more. This was all on dynojet as well...when comparing dyno numbers you have to figure in Mustand / Dyno Dynamics or Dynojet. Mustang will read 12-15% lower than Dyno Jet....and I swear I have seen somewhere on here someone making 260s on a Mustang with exhaust and intake which would translate to 290+ on a Dynojet. That is where I expected to be after tuning.

But I am having a local shop make upper plenum and throttle body spacers for me, and also getting thermal coating on the upper manifold and see if any of that helps...heat soak is insane on this thing.

Please keep us updated on your numbers, and the improvements made to achieve them.

I have to admit, for a 10hp gain I would not do the tune, there is simply not enough return on the investment.

[svard75]

Guys. You have to be realistic here. The tune is just tweaking the ecu to dump more fuel when needed and advance timing. It won't magically give you a supercharger. Was your evo boosted? Turbos are much easier to tune just move the wastegate pressure or replace the spring on it. Na cars have to use their displacement for the hp and torque. Honestly though a v8 loves to breath especially the intake and exhaust. You said those were done but what aspect of them? To really make these v8 s shine get a 3" mandrel bent header back exhaust with test pipes (only for track use) and sure give the plenum a shot. The tricky thing about just putting a plenum spacer on without flow benching the entire intake and heads is you could change the harmonics of the intake tracked which could actually reduce velocity of airflow. I wish you could try before you buy for something like that. I would try to have motor dyne build one for you instead of just a random Cnc shop.

[M4point5]

Sure boosted is easier to achieve the numbers - thats not the point. I am trying to justify $750 for 10hp...trying to gauge where everyone stands and see if my tuner just didnt give a s*** or what. I mean, he tuned the car in 3 pulls....

Aside from that, theres no point in a 3 inch exhaust system when the restriction in the stock header design isnt going to allow for full use of it. There is basically zero aftermarket support for these cars which is sad...custom header shop here wants $400 PER runner on a set of headers. No thanks, not building this to race.

There is too much emphasis on "peak" numbers. Can you post up the graphs of before and after the tune?
Did the tuner remove the throttle lag (stock, WOT under 10 mph or so still only gives abut 60% opening) --- UpRev can remove that.
What A/F ratio did the tuner calibrate to?
How many miles are on your car and when did you last replace the plugs?
What intake and what exhaust (mufflers, mid-pipe, Y-pipe) are you using?

I have not put my M on a dyno but I do a lot of monitoring and my UpRev tune (done by Seymore4 here on the forum) along with my supporting mods dropped my 0-60 time (when I have traction) to ~4.5 seconds. Plus a whole host of other benefits.

Honestly I can't tell you anything about the tune - I couldn't even get answers from the tuner. I couldn't even get the freakin tune file. I am more than dissatisfied with the way things went down that day which is why I said I will be going to a different tuner this next time.

85k miles, I changed the plugs out the day before the tune. The plugs were shot - and yes I used NGK Double Platinums. Injen intake and a custom exhaust setup...true dual with secondary cat delete. I will take a pic of the dyno graph and post it here in a few.

[DeanM45]

Are you using an "X" pipe in the exhaust?

Dude 3" pipes!!!

Let me tell you a story that will hopefully make you feel better. A friend of a friend of a cousins nephews friends brothers mother... Had a porche cayenne non-turbo spent $6000 on a new exhaust and intake and an ecu tune and gained 6hp over stock. The cayenne was already pretty tweaked from factory. Similarly I believe the m45 is pretty tweaked from factory. That said you mentioned the tuner you used finished in 3 pulls?! He definitely cut corners. For my experience we filled up the car and jumped on the highway. 4 pulls just to obtain readings then he had me do 4 pulls while he played with the ignition timing. 4 more while he played with the cam timing then 3 to check them together. 2 hours later I had my tweaks done.

That said has anyone heard of their cars going into limp mode often while driving normally through the city? No codes but initially the tuner noticed my car doing that often due to excessive knock. I always used grade 91 or higher octane and my mods are ported polished lower intake plenum. Z tube and skunk2 spacer. I'm not burning coolant cause the level in the bottle has been the same since I flushed it 2 years ago. I do burn about a litre of oil between changes. I'm going to add a can of seafoam next fillup and next oil change switch to 15-w50.

What tune are you running and who did it?
If it is not stock then it sounds like too much ignition advance. How many miles on the car? Have the injectors ever been cleaned/checked for balance?
What heat range of plugs are you using? When were they replaced?
What is your intake air temp value (IAT)?
Wait till the car is cool and pull the radiator cap off. Is the radiator full? You can have cavitation and/or a defective radiator cap which prevents the coolant from being pulled in from the overflow.

[svard75]

Street tune. Even before advancing the timing he was seeing knock. He even retarded the timing quite a bit and it didn't help much. The funny thing is after doing all my hard pulls he told me its much better. It went from 2000 to less frequent 100s. I am not sure but the car does feel different when its cold from driving a few miles It feels a bit more sluggish.

The engine has 165k Kms on it
Plugs are Nissan standard, replaced 2 years ago or 60,000kms
Don't think I ever cleaned the injectors. If it was part of a maintenance program then perhaps they were.

Ill check the rad.

Sorry to derail this thread!

IMO three pulls is not enough. Mine took about 2 hours and from other members it took about the same. There was another member that was tuned at the UpRev main location and had a gain of nothing, hp wise. He had the injen cai and stillen exhaust. The car ran better from what he said and it felt stronger but the dyno graphs were disappointing...def keep us posted on your new mods and if your shop will produce more parts and for how much.

I may as well just write it all out now. "The tune" took 7 freaking hours...my appointment was at 11. I show up at 1045, "our tuner isn't in right now - he will be back around 12:30." I leave the car, come back at 12:30...still not there. I WAIT at the shop and he finally comes at 1:30 and tells me he had to help "a customer" tow his car. Now, this shop has gone through quite a few tuners and can never seem to keep one. To my SURPRISE, the guy who was going to be tuning my car was the SHOP OWNER. Couldn't call me to tell me he would be in late, nothing. That's nearly 3 hours gone now.

I wait ANOTHER 30 minutes for them to push cars around in the shop so they can get me onto the dyno. Strap it down, blah blah. Now he does one base pull and turns the car off. Fiddles around on his laptop for 30-45 minutes. Does another pull then turns the car off. Comes out and tells me the car is too heat soaked to run it anymore so he is going to go get lunch and try again in 45 minutes.

45 minutes goes by and he's still gone....finally after an hour, he comes back and says the engine is still "really hot" so he can't do another pull. I tell him to do it anyways and let's get this finished because I have been there all day. He waits around 30 more minutes then finally does another pull, plays on the laptop then says the tune is done. After I get the keys, I try to get the tune file - no sorry we don't do that we don't want people stealing our tunes. OK - that did it...$750 for jack s*** basically...I made it VERY clear I wouldn't be back to his shop.

And that is my experience...I will be going where I SHOULD have gone in the first place (shop that specializes in Nissan)

WOW! I would not go within a mile of that "shop"!

[M4point5]

Oh trust me, I will not. I have NEVER experienced such poor service at a shop. The other shop I will be going to is pretty good - they were a month out for tune which is why I gave the other shop a try. Even if I don't gain any power, at least I will know exactly what is done to the car and that it is done RIGHT.

Edit: Dyno Graph. Not sure why the picture turned sideways when uploaded.

[CPJ LB]

Man... Sorry to hear about your experience with that shop... Hopefully Uprev will recognize if that shop has received a lot of complaints and do something about it

Anyway, I'm curious to know what gear the tuner dyno'd your car during the pulls -- brief pulls I might add!!! I hope he didn't do the pulls in Drive or 5th gear!!!

I hope you have better luck with the next tuner..

Regardless of which dyno used, the Uprev tune should have yielded more gains for you.

From personal experience, I yielded approx 50-60 hp gain from my baseline run after my mods & Uprev tune... The shop I went to and still go are real car enthusiast!!! Sti's, Evo's, V-Tech, Cts-V's, VQ's....
They tune them right.... Let us know how the new tuner does..G/L

[M4point5]

It may have been a 4th gear pull - I really don't know. There were only 3 pulls and such long waits in between - I was getting frustrated by the time it was even ran on the dyno again.

25-30hp I would have been content with....what mods did you do to net 50-60hp and what was your AFR like?

[CPJ LB]

Here's a copy of one of my old posts during a discussion here about Uprev tuning:
The numbers listed below we're prior to adding HFCs -- the gain from the HFCs were approx 10hp / 9tq

it's fine that you're doing the tune Ilyakol...like you said, the short list of mods you have will be fine without a dyno.

in addition to the eco map, my tuner has it set to where if I were to floor the gas or get on it...the sport tune automatically kicks in -- that was a bonus feature. (for emergency purposes like getting out of harms way, etc)

I keep my setting in 'sport' for the majority of time...but also in eco setting.

my mpg has ranged from 15 to 19mpgs (depending on the type of driving and setting)

as far as power added from the tune, yes...it's provided, but it also depends on the supporting mods...here is a breakdown of my prior dynos and I've had the Uprev for over a year.

FACTORY RATED 06 M35sport at the flywheel = HP: 280 TQ: 270 (which is rated very low at the wheels)

Initial Uprev
3/22/11 - Baseline run 91 octane
NEAR STOCK (K&N drop in, stock mufflers w/xpipe and 2.25"piping from cats) =
power at the wheels:
whp: 229 @ 5953 A/F: 13.79
Tq: 228 @ 4938

3/22/11 - Adding TUNE: UPREV w/Osiris
power at the wheels:
whp: 252 @ 5952 A/F: 12.98
Tq: 238 @ 4767


4/18/11 - 91 octane(5/16 MD plenum spacer, K&N drop in, z tube, 2.25" dual exhaust piping from cats - xpipe, high flow resonators - to stock mufflers)
power at the wheels:
whp: 265 @ 6300
Tq: 245 @ 4745


11/15/11 - 91 octane
(5/16 MD plenum spacer, MD MREV2, MD Isothermal gasket, K&N drop in, z tube, G35 Ypipe,Megan exhaust 2.5"mid pipes & axle backs, NGK spark plugs)
power at the wheels
whp: 282 @ 6408
Tq: 255 @ 4693

*Test run for lower end tq: 270 @ 2691 rpm

I now have HFC's and will put on the Motordyne xyz pipe to get a test run on numbers, but from my butt dyno, since adding the HFC's I've felt a huge difference in overall power...the car definately pulls hard.

Driving in manual mode allows you to use the entire powerband...I don't go past 7000rpm to prevent wear and tear of the rods, springs, etc(as you can see the majority of my HP is at approx 6500rpm's)...those that have built motors don't have to worry about going "too" high in the rpms....

the best thing I enjoy is the drivability of the car..."its more fun to drive"....

[M4point5]

That's the thing I am most frustrated about. If I wanted 260 to the wheels, I could squeeze it from a V6...heck, even 4cyl's are in the 200s these days from the factory. Two more cylinders and 1 more liter and such poor numbers. I will definitely be getting retuned after I have the spacers made and install them.

I am also going to test and see exactly how much the spacer helps the intake manifold temp (I will be having it thermal coated as well). Just have to find the old temp gun.

[CPJ LB]

I feel ya man!!! I bought my car used and went ahead and changed all of the sensors, PCV valve, plugs, fluids, installed grounding kit , etc... Our cars are super sensitive when it comes to the cam and crank sensors. Might want to check yours.....

[M4point5]

Got mine used as well and did all the maintenance on it since I wasn't sure when it had been done. Then did my VIP build on it and now trying to get a bit more power out of it to fully finish the build. Too many electrical components these days...miss the older cars where all you had to worry about was fuel, air and spark!

[mexillis]

Pics of the vip build? Also what air set up did you go with?

[M4point5]

I will make another thread with pics, as to not clutter this one. Accuair e-level

[seymore4]

This whole thread really validates my point of not getting a dyno tune... For $500 out the door you can get the exact same gains with etuning, plus you own the cable. If you just have the shop reflash you like that you've got no way to remove the license and transfer it onto a different vehicle or sell it used... Sucks but the OP is pretty much out $750 :/

OP PM me where you got tuned if you don't mind.. the dyno sheet looks familiar, I might know them

[06M4.5]

I'm sorry but IMO I wouldn't get the Uprev without the dyno. Every car runs different so every car should need it's own tune.

I have seen it with my own eyes when Robert got his Uprev tune done and then I got my M done at the same shop with the same dyno. Both cars ran different. This is not paste & copy people.

With the dyno it's more controlled, you don't have to run on the road and take a chance of something happening or even trying to explain to the cops of what your doing.

And both Roberts & my car was tested on the dyno on 4th gear, my car was running 148mph on 4th gear only

If I had to do it again I'll be doing it on the dyno again for sure.

??? No one said anything about copy and pasting.

Watching someone tune your car and then listening to them explain to you why its worth all the money you just paid without actually having a clue whats going on besides watching your car on the dyno and actually tuning cars yourself so you understand whats happening are completely different things.

[06M4.5]

I agree and still rather do it in a safe manner.

Getting a good tuner isn't easy. Thats why I thank Robert for finding the tuner we went too.

Freddie i had two choices Long Island or New Jersey, I chose JDS motoring NJ because it was closer. Im glad that we went there and got our cars tuned. We watched everything from the start to the end. The guy ran my car at least 10 times on the dyno. Its nice to see what they do with your car, when you paying $600.
