UpRev'd my M45

[mexillis]

So since there wasnt enough interest in a group buy, I decided to go ahead and get it done by myself. I went to Function Tuned in VA, and man was it worth it. This is on a dyno dynamics so the numbers run 10-15% less than other dynos so here's the numbers.

Base run 232 HP/ 262TQ

Final run 262HP/ 292TQ

So i gained 30/30!

I did a 12% increase to simulate other dynos and it turns out to 294HP/326TQ.

wow!!!!

awesome man! tell me, how does she feel? how is it on the freeway when your cruising at around 80 and mash the gas? does it pull alot harder than it used to?

[dvan]

WOW!!

What was the total cost for you there? Im sure your exhaust upgrade really helped you get to that 30HP mark. I'd say it gave you the other 20 HP, since HugeDude gained 10HP in stock setup.

[mexillis]

it feels better in every way, and my exhaust only gave me 10/10 or so. another M went there bone stock and gained 20/20. it's all in the tuner i guess. i got a military dic. so it will b diff. 4 u.

Dude..20/20 stock at that place? ima have to do that.....

Mil discount ...damn shoulda got this done before my EAOS in december last year

[saeedakobiakov]

NICE.how much for the uprev?can i get it for y34?thanks

[saeedakobiakov]

just talked to the dude at up rev. no good news for y34. older style of ecu. Thursday taking out my bottom cats. i hope it's not gonna be too loud, but i kept the valve on one of the exhaust pipes with which i can adjust the volume with .

dyno dinamics is the s*** though.

[dvan]

Mexillis,

How many dyno runs did you need to do? How much power did just the tune add on the first dyno run? Do you know if the dynoruns are a requirement or can you skip it and just get the tune? Thanks

[mexillis]

If people wanted to get the group buy i was tryn to set up we coulda all saved a 100 bucks but o'well.I think it was about 5-6 dynos i dont remember exactly. I didnt pay attention to the numbers but after each dyno he added more power. If you want to, you can just buy the package from UpRev (Osiris standard) and pay 500 and they send you tunes. Also the tuner mentioned to me if anyone wanted to go that route he could make a E Tune for anyone interested, you'd get 3 free from Uprev and if you wanted to try and get more out of it you'd need to buy another one. I dont know how much you'd gain but i would think no matter what it would be worth it. If you payed 500 for the Osiris standard from Uprev and then needed more tunning you'd still be saving money.

[dvan]

Thanks Mex, i wish I could have gotten that group buy with you before. Its been a hard sell to the wife who thinks my M45 is perfectly fine the way it is and there is no need to spend 700 bucks on it lol (damn houses and kids! j/k). I'll keep workin her over eventually ill get my way

[nmgoodthing]

What the heck? How different can the ECU be then 2nd gen? So much for buying the Tuner package I was going to get.

Probably not too much different in it's overall design. But for them to reverse engineer your ROM and patch it to make it tunable is a whole different story.

It's been desciribed as trying to find an address in the United States without the city, state, and zip code. So if I told you I lived on 1724 E Broadway Rd - it makes sense but at the same time it makes none either. What uprev does is they have to go and find all the addresses in the USA that start with 1724 E Braodway Rd and verify you live there.

If you want more power - just get the Cipher and do the 2 degree advance. Then if you want more then just buy a nitrous kit and run a 75hp wet shot and use the Cipher to pull the timing. Price would be about the same as a Tuned Uprev.

Just spoke with Richard from up rev about cipfer. he said , not gonna work on y34.

What I really wanted a tune for was to optimize the stock tune with my catback exhaust I have. 2 degree timing advance would be nice too, but as Caug said I guess it won't work on the Y34:-(

No nitrous for me. This is my daily, just wanted a little optimization of A/F at our ridiculous altitude here, and Uprev seemed the way to go with out putting a standalone which is retarded for what I want.

If I had an extra ECU I'd send it to them and see if they could crack it. I'm sure there are a handful of Y34 guys wanting a tune.

All the Nissans we have tuned here before tuning with Uprev (G'sM's 350's) that had intake and exhaust where running scary lean. Please get a tune boys and girls if you modify your intake and exhaust.

That's weird because I've already done the 2 deg advance on a Y34 for M45Caliber. It works - I wouldn't suggest it if it didn't. Oh, and the Cipher will actually tune my car also. It's not supposed to but it does. Ha Ha!

[ken in az]

Oh - and mex - sorry to derail the thread. Great numbers!!!!

[mexillis]

It's all good, next will be big brake kit and then G37s diff. gota have some LSD

Do doubt - that right there put the biggest grin on my face.

Here's a little story for ya from this morning. Light drizzle and pavement was wet, pulled out onto one of our 7 lane side streets we have here in AZ (rural road for the locals) - no one coming or going in any direction. I pull out in 1st gear pretty straight knowing I want to sling the car sideways a bit, I give it just a hair more throttle and whip the wheel just a tad more aggressively than I normally would. Transmission shifts to 2nd and initiates a slide - I throttle into it to maintain the rear wheels a spinnin. So here I am holding a power over drift at about 80% full lock on the steering wheel...carry it for a little and smoothly transition into my lane and proceeded to get on the freeway and continue to work.

VLSD makes me smile

[hugedude33]

C'mon man, 30/30. thats insane and you said someone else got it done with a stock car and got 20/20. if thats true I think I need to pay R/T Tuning another visit. I only got 10/11 with a stock car. They didnt go crazy with the tuning cause I was thinking about getting a exhaust. so they tuned the car for only a hour, but to get a real good tune, it would take about 2hrs. they split the dyno time in half to save me money and the 2nd hr would be done after the exhaust. In not getting the exhaust anytime soon. if I can get 10hp more with a stock car its worth the $150 for dyno time

[mexillis]

here's the thread where the guy gained 20/20, i thought he was bone stock but i guess he had mufflers, but i doubt that does anything. Anyway here u go hugedude

zerothread?id=459592

[hugedude33]

by the way, what is a g37 diff

[hugedude33]

thanks mex, I read the post and yes he had his muffler done. what kind of exhaust do you have and is it loud. I want to get a exhaust but I like the combination of lux-sport. I dont want my car to sound like a american muscle car. do you have any other mods done to your car

[mexillis]

here's what i found to describe a g37 differential= viscous limited slip differential, found it on a g forum, but it can go more in depth with more searching. Also my exhaust is only loud when i floor it, which is what i like, some may not but it's ok. I have a thread on it but so u dont have to search, 2.5 in S.S. no cats, no mufflers, just magnaflow x pipe and quad 3.5" tips all for way less than megan mid pipe back and less than stillen, which is what i like the most. If you want it to be more quiet just add mufflers and magnapacks (resonators). Thats all i have done on my M45, no other mods. Also i know that the other guy had A.M. mufflers but that didnt gain him 10/10, no way. Our mufflers are free flowing just ask ken he did the find/resaerch if want to call it that.

VLSD = viscous limited slip diff

The stock viscous limited slip works by immersing a series of round plates, alternately attached to an axle or the differential housing, in a fancy viscous goo. When you go around a corner, the outer wheel will turn faster than the inner wheel, but because the differential housing itself is going at a speed halfway between the two wheels, the differential housing sees the outer wheel turning forward and the inner wheel turning backward.

The plates can be stacked various ways, but let's assume that on each side of the differential there are eight plates, with half of them attached to the axle, and the other half attached to the differential. Call the axle plates "A" and the differential plates "D", and they will stack up like DADADADA.

The plates in a viscous limited slip don't actually touch each other. Instead, they are separated by a thin film of this viscous goo. When you go around a corner, and the A and D plates start turning at different speeds, the goo trapped between them heats up. Some chemist somewhere figured out how to make a magic fluid that expands and thickens under this shear load, making it more difficult for the plates to go different speeds.

While the fluid tries to lock the plates together, the tires try to rip them apart. At low speeds and gentle turns, the fluid doesn't get thickened much and the tires win. Boot it and try to spin one tire and the plates suddenly are going dramatically different speeds. The fluid thickens just as dramatically and, with the stock tires, the fluid wins, locking both rear tires together and letting you have your glory slide. A little less throttle and you have the smooth, seamless acceleration Nissan engineers had in mind. If you have really sticky tires, though, the tires win, and the long, gooey molecules of the stock diff's viscous snot get sheared into smaller, less thermo-reactive visco-thickening stuff; stuff that would make that mysterious chemist blush with embarrassment.

What's up guys.....my name is Chavez. I joined a while ago but haven't said much on here. Anyway I just UpRev'd my M yesterday at Function Tuned in Northern VA and MANNN did it make a difference. First I had the Sprint Booster installed on Friday and that was worth the money alone because of the responsiveness.....followed by the UpRev yesterday. Here are the numbers:

Stock Pull: 230rwhp (that's with CAI, exhaust & sprint booster installed)UpRev Best Pull: 253rwhp

That's a gain of 23rwhp, a little more for tq. Was it worth the money??....I'm not complaining

Now of course I picked the warmest day in the DC area in 9 months to get a Dyno. It was about 72 degrees (not to bad), but the car was definitely not cooled off enough for the best numbers after the long drive to the FT shop. Dave, the owner, is a knowledgeable guy and tune extraordinaire and acknowledged that a gain of 30/30 is highly likely for the M's as stated by Mexillis, in ideal conditions. And as stated before on this forum, Dyno Dynamics normally produce numbers 10-15% lower than other dyno's; Dave believes it's 15% in my particular case.

That means my 253 is potentially about 291rwhp/322tq, give or take. Either way it feels GREAT.....I'll post the graph a lil later.

Now it's time to figure out how to get this Stillen Intercooled Supercharger for the VK56's to work on the M. Maybe I'll start a new topic about that.

Sorry so long

[caug1]

Ken, I dont lie about this stuff. just repeating his words.i will do anything to go faster.Will call again.

[speed_addict]

Great job man!!!!I need to know did you changed your ecu or fitted the uprev engine manegment next to the stock ecu . please can you post more pictures.

[rowland220]

Amazing, i am so juiced to do my tune but really wanna wait for headers and to see whether these guys can do anything with my intake mani, Does anyone know the best place to go for the uprev in Socal. Im new here so any help is appreciated

[Royal1262]

I hear everyone that did the Uprev tune talk about the dyno, but never heard anyone say whether or not they felt a difference in power while driving. Did you feel a huge difference in power?

I'm sure I can speak for mexillis when I say you can DEFINITELY feel the difference....just ask my wife. I normally drive in "stock" mode rather than the "performance" mapping just because of the throttle sensitivity (keep in mind in my case the Sprint Booster plays a huge factor in that) and too much fun= poor mpg . I've primarily mastered the tiptronic and 4th gear at about 80mph is amazing! I highly doubt you'll find anyone with a different answer....20-30whp presence is felt, unlike adding a simple cai/exhuast.

[hugedude33]

how is the gas mileage after the tune. most of the time I keep my car in the stock tune. I only put it in the UpRev tune when racing someone or when I'm on the expressway. in the city I keep it stock cause the MPG is HORRIBLE in the UpRev tune. whats your take on that. I only gained 11hp and 10tq cause my car is still all stock. you gained 30 so I know its eating up more gas
