Got my car tuned with UpRev
 

So I get a call from a local UpRev dealer saying they think they might be able to tune my car (been hearing that for the past year now). They ask me to come in and have my ECU ROM file read and sent to UpRev in attempt to have it cracked and what do you know...

A few days later I get another phone call saying my friends G37 (Gulf Spec) was tuned flawlessly! I book an appointment and get down with that!

My current mods are: Stillen G3 Intakes, FI Test Pipes & Catback and UR Crank Pulley. I'll let the pix do the talking now:

And we're ready for action!

Almost an hour later, the tuner was done. My main issue of running too lean was solved thankfully as you can see.

According to the tuner, unlike American Muscle cars which he tunes a lot, our VQ's barely respond to changes in AF ratio in the power department, but reducing the AFR to 12.5 ultimately allowed him to push ignition timing even more which was the key! I honestly was not expecting that much of a gain but that tuner seemed to know what he was doing from the first phone conversation I had with him. My maximum power came in at 7200rpm before the tune, after messing with AFR & Ignition Timing, the car kept pulling up all the way to 7600rpm!

Here's a video's of both runs:

And finally, the dyno sheet:

Before the tune, I put down 262whp @ 7200rpm & 289 N.m
After the tune, I put down 296who @ 7600rpm * 321 N.m

I was very impressed with the numbers, but those don't mean anything if my butt dyno doesn't confirm. So I took the car out for a spin and all I could say was wow. None of the mods I ever installed ever felt like that after their install, you can feel the gains from really low. Even on 5th on the highway, it's takes less effort to speed up. On 1st, don't even dream about driving in a straight line on tarmac. We went Auto crossing today and it honestly felt a tad harder to drive due to its tail breaking loose with every blip on that throttle. I cannot be any happier to be honest, not without boost at least lol

Another cool trick they did was upload a valet-map which you can cycle to via cruise control. The valet map basically limited the revs to 3k and the speed to 70kph (43mph) I recorded a ghetto video of that:

Don't waist your time on preloaded maps or maps that don't tamper around with your ignition timing. UpRev is the way to go!!

My G is back to life!

34HP and 32TQ gain from a tune and nobody is commenting on this?

LOL well it has like 50 views or so, I just thought I'd share since it's the same engine

good deal man !

Awesome gains! Not what I was expecting at all.

Yeah same here wasn't expecting numbers in the 30's to be honest..

As I started reading, I was guessing ~10 in my head. You blew my mind sir.

I'll pass that message to the tuner :tiphat:

That's freakin awesome man... I can't wait to get mine tuned... I'm sure its runnin' lean right now... I was leaning towards the Cobb but these results are really nice...

I'm sure it has a lot to do with the tuner though. I need to find someone that knows what they are doing around here.... Still have yet to do that.

So what does the Uprev tune do now?
As far as I was aware it can really only mess with AF mix, Uprev has not cracked VVEL nor timing table.

I havent read anywhere about someone cracking the VVEL but UpRev can mess with your AF and Ignition Timing. I was running around 34 degrees BTDC at high rpms before the tune. He wouldn't give me the after tune though lol

Sounds good, I am not sure if any has cracked VVEL but just wondering if that contributed to your awesome gains. Guess not, which makes them even better. :D

Wow, now this is more like it! I've been very disappointed in the gains from tuning until this post. Hopefully more tuners can pull off those types of results!

Oh snap. That is what's up. I just hope I don't have to go to Canada to get that kind of tuning done, lol. It would be a looooooooong drive.

Yeah I really wouldnt mind someone messing with my VVEL especially with the Long Tube headers combo

:werd:

Exactly, I am really wanting to get a tune once the LTH are on but was hoping someone would crack VVEL by then.

Awesome stuff to see Sam. Really might have to start looking into this myself as we have the same setup. Different car body though LOL.

Do the mustang dino's usually read that low? Isn't 260's low for a baseline with those mods? The G37s get almost the same numbers as a Z with those mods right?

What is this tuner doing that the rest of the Z tuning world has failed to do?

What is the name/number of this tuner?

And to clairify... Your baseline includes the CBE, Intake, etc....right?

Yes, as mentioned in my thread my baseline included I/Test Pipes/Exhaust/UR Pulley

The Mustang dyno is known to read low, theirs for some reason reads way too low. An HR 350Z read 205-210whp before my eyes

I was speaking to a local Uprev tuner and he told me that his contacts with Uprev and japan have found a you cant just tune these engines like any other car and expect gain. He said it needs to be done in an unorthodox method a 'certain way' to actually yield large power gains instead of the tiny ones we have seen. Ill know for sure when I get my headers installed and will be sure to post my results when its done. I couldn't get anything out of him as to what he was hinting at, but apparently there *is* something special that can be done to get these kinds of gains NA. Did your tuner tell you what he was doing by chance?

great gains Sam! i know you cant wait for the FI LTH! do u have them pre-ordered?

Yup ;) my name's number 2 on the G37 list :D

Never will a tuner tell you what he did, he wouldn't even let me datalog after the tune. It's his secret recipe. But I know for a fact that he advanced timing big time as it was VERY retarded before the tune as my datalogs showed me

IMO the secrecy seems a little shady to me. How do we know if this tune safe is if we don’t know roughly what was done?
(tuners…help me out here) I know very little about tuning but correct me if I am wrong… Couldn’t you dial in some unsafe peramiters that would yeild higher numbers in the tune but then cause the engine to run in ways that will cause damage??

The worst that can happen would be your engine knocking from the advanced timing but our engines are smart enough to retard that once it senses knocking thanks to the knock sensor.

My AF ratio is at the optimum level too, can't complain much :)

man thats crazy. I'm planning on going back in to get a re-tune once my headers and pulley are on

Those are some great gains with the tune, Sam!

And to echo everyone's comments already... the Mustang dyno's read low.

NOICE! i'm #11 here :)

Wow, those are some epic numbers!
Good stuff. UPREV is real big in the VQ community, and they never cease to impress.

True that, it's one reason GTM uses their flash in most of their turbo kits

Surprised more people are not commenting on a 30hp gain from a tune.

I just realized this tuner is in Dubai....dammit

The 30whp gain is also due to shifting from 7200 to 7600 RPM too, I didn't make the claim and run away, I scanned my dyno sheet for you and posted up

Great results!
Would love to get a clip of how your whip sounds!

I posted dyno video's in my first post did you miss them?

Is it just me or is 260 whp with intake test pipes and catback even on a mustang dyno crazy low? Id imagine the gain from the tune is in large part from correcting what you apparently didnt gain from breather mods. Nonetheless assuming u were at 240 whp stock thats still a 50 whp gain if ur at 290 now with tune.

+1 True...
Shouldn't you have atleast high 270's stock?
I thought you would have at least 314.

I think 240 was his baseline with some mods, but he went back with more and ran 262 before he got a tune and then 290+ after the tune.
You guys have to realize, not all dynos are the same, yes it is a Mustang but that does not mean it is going to read like ones in the states. Weather conditions, altitude, etc. all play factors into these read outs.

+1 to what Dreamer is saying. Mustang Dyno's aren't the same. You can choose the "load" you want that dyno to have before buying it depending on HP ratings of the cars you'll be dyno'ing. That Mustang Dyno could measure up to 2000AWHP I believe.. so you can imagine how low it will read for us. I did put down 262whp with all the breathers, didn't do a dyno run when I was totally stock so I can't comment on that however, on a dyno day a while back on a dynojet, my car put down around 30 horses more than a bone stock G37
