at the end of the day its not about peak power but about the over all total power band

this kind of power band nets me more mph than a real peaky power band of 320 all cars are diff. but again peak numbers dont mean much but.....


my car also did this... so if we want to talk peaky numbers we can do that too.... LMAO I'm a tool sry.

 

I'm not sure how these rumors get started. I have posted the following several times but here it is again:

Vince is a former Microsoft programmer. He actually developed his own, unique, software language to allow the "GT Tuner" to communicate with the cars pcm. I can't remember the exact number, but Vince wrote several thousand lines of code to accomplish this. So he isn't just a guy who knows how to tune the cars pcm, he is one of those very few guys who actually writes computer language to allow companies, like the other company mentioned, to offer software packages.

As mentioned, the tune he offers must be reliable and safe. Not pushing the extreme limits for every last ounce of power, rather offering a tune with great drivability, great power and safe/reliable was the objective. For those customer wishing to schedule dyno time with Vince to further customize their tune, they need to simply call him and find a local dyno. Vince can remote, CUSTOM, tune their car from anywhere in the world. No other programmer/tuner is currently capable of offering this.

With the additional adjustments he makes, the air/fuel ratio he sets, was found to be optimum; on the local car, with local gas, on a local dyno in the winter with 30 degrees farenheight.

The same tune is going to yield different power and torque results on other dynos, as well as at different elevations, humidity, temperature, etc.

The only accurate way to compare one tune to another is with the same car on the same dyno on the same day. All else is speculation. Track results will also differ for the same reasons above. Back to back 1/4 mile runs with different tunes in the same car, with the same driver would need to be done.

I hope this helps.
Thanks everyone.

 

That is pretty cool. I did not know that he did that. Mad props for cracking the ECM. Takes a ton of computer skill to do.

 

see i knew he had something different, but he rarly will talk about it or let you know and i do not blame him.

 

That is cool. Does he have access to the fuel pressure tables in the ECM?

 

Yeah, not sure i have only seen some of the tables by a quick glance, like i said he doesn't want much info to leak out he did all the dynoing on my car by himself as i watched.

 

Oh, ok. My clutch is slipping now too much torque now that I ramped up the DALs in the midrange a lot. . Just have to baby it most of time now I guess . New clutch is not in the budget yet.

 

im with you on the clutch... mine slip around 5k

 

Vince has done some pretty incredible things with stock PCM's. He has an LS1 Camaro and manipulated the programming in the stock PCM to allow a nitrous system to opperate. All PCM controlled through tuning without needing window switches. Basically, when the nitrous system is engaged, the fuel pressure increases automatically. We have talked about this type of system for th Cobalts but no plans at this time. But you never know.

 

vince for president!!!!!!!

 

U must have dynoed on a mustang dyno... they read overly high.....95% of good racers and tuners will use a dyno-jet...

 

please step away from the computer

 

dude EVERY thread you post in you are VERY wrong... all i can do is shrug

 

trifecta tunes are in no way and cannot at all be described as canned unless you choose to not datalog and update...then its your own damned fault

ok..didnt read that dan had posted :P

ya...vince did what hp tuners COULDNT do for the L61....he is the ONLY tuner becuase he can do what he can with his program...and let me tell ya what...it is something else to watch the guy go through streaming code and edit it to tune the car lol

that was a fun car to ride in
doesnt have it anymore though...just the impalla and the corvette

 

hey guys, imnew to the whole SS world and the electronic tuning...just wanna put that out there before i chime in. if the trifecta tune is makin the majority of you guys runnin rich, cant you just get it dyno'ed and have that adjusted by slightly increasing boost so the motor is gettin more air?

 

Where are you getting this info?.....Find a new source because it's just nonsense

 

Just ignore him. He has no clue what he is talking about. It is true that is a mustang dyno operator inputs improper numbers for curb weight, Cd, etc it can spit out pretty high numbers, but if done properly a mustang dyno generally reads 10% lower than a dynojet. Tuning is best done on a load type dyno that can replicate real world loads. Some dynojets are load cell some are standard models with no loading capabilities.
