Tune The GT

[Fubar]

I need to retune the GT. I'm not thrilled with some of the side-effects from my last tune. Anybody know some good Ford guys?

[brian_k03]

like what?

[RaceMX-M3]

Mark from what I've heard the Ford tunes are pretty basic. I will drop by with my laptop later... and then we can do some test runs. ;)

[BlackSheep]

Sounds like a pulley change to me.... Talk to Taylor.

[Fubar]

Too much heat in the exhaust.

They are simple compared to the BMW computers but I need someone who understands the tuner software really well. There are some setting that can still get F'd up.

hmmm, 23lbs of boost does have a nice sound to it but so does this:

^jesus

[Fubar]

pretty uh?

I wish it were mine but it would require a rebuild on the motor.

check out the guy's "Go Switch"

Wow that is sick!!! Glad it's not your's Mark!

Go Baby Go

That's cool as hell.

Do you prefer local or are you comfortable with a mail order tune completed via datalogging?

Manny at HPP is probably the best local option.
Justin Starkey of vmptuning.com and
Jon Lund are also popular.

Mike Murillo in San Antonio would be my suggestion. He did my dad's cobra, and a good friend of mines Saleen. Mike does a lot of fords, not sure if gt's are his thing but if you don't mind the drive maybe give him a call.

[RaceMX-M3]

I would think someone should be able to do real time dyno tuning remotely.

[Silentrun]

My ECU is in Europe...3 months of stock tune. Good luck Mark. Question, if you have traction problems now what will having NO2 do for you?

[Mr.Big]

hard to argue with Taylor's custom fabrication and tuning success on Kumar's GT... Went faster than several cars that had more rwhp than him...:thumbsup2:

[Fubar]

Did Kumar's car go faster than other GT's with similar hp?

I think there is a global timing setting that has been changed but I need someone who knows how to look for these things in the Ford software. I am afraid that most "Ford" tuners will expect the the GT motor to respond like a typical Shelby 500 motor... it doesn't.

Who tuned the whippled-N20 GT from Houston? He went north of 225mph right? I would start there if I were you Mark.

[Fubar]

That's a good idea.

[Mr.Big]

you would have to answer that, not sure on the power of the other GT's that were there, I think he made right at 100rwhp more than you when tuned for the mile, how fast did you go? that might give you an idea of the potential... but not sure on the other GT's there, I know he made almost exactly the same rw as a couple of friends that ran the mile and they were right at 200mph...:thumbsup2: not sure who had better aero, so it is and was a general statement, and just for power reference...

[Mr. Hollywood]

That's a good idea.

I try. Talking with Matt today, he agrees also...compared to the local alternatives.

[Qship5]

That "Go switch" is awesome!!! I'm sure you'll get the tuning sorted out as it seems there are several good options being posted up in this thread.:thumbsup2:

I try not to get too caught up in whp numbers as they can vary so significantly and tend to mislead. Also from my experience whp on a turbo is *usually* > the same whp on a supercharger... although Mark's torque curve is the best I've seen from a supercharger setup. IIRC Mark's 780 ish whp GT beat Kumar's 1000+ whp turbo GT although traction may have been a factor. At the end of the day I think dyno's walk and 1/4 mile traps, ET's, or 60-130 times talk.

[BlackSheep]

I think Kumar's TX mile run of 214 is nothing to sneeze at.. especially when it was the only car to hit 200+ that was driven there and back.. Thats the fastest car on this site by a big margin.. I think when Mark and Kumar raced there were some issues with Kumar's car.. That car is a beast, no doubt.. That being said!! My car will be ready for any takers tomorrow!:D

He is not Hennessey, is he?

[Mr. Hollywood]

I said TUNED not built.

He may be a credible tuner, but I just could not trust the guy.

He usually subs out this tuning. Justin Nenni of Tuning Concepts is phenominal.

[BlackSheep]

I had to leave a comment on the youtube video......:whistle:

[Fubar]

Kumar's car wasn't tuned right the night we ran. It was fun but I'm certain his car will get down the road faster than mine. I think there were several other GTs that ran 200+ that also drove back to Austin afterwards. The N2O-Whipple car ran 218 but I think he used race gas to get it done. He had a rwhp of 990ish.

I spoke with him today and his tuner is in Houston. He told me (what I already know) which is basically that this is hit or miss with tuners. They don't have the magic fix. A proper tune should take 3 days on a dyno and 1 day on the street but nobody invests that kind of time in tuning.

The parts I need should be in next week so hopefully I can get the GT out in some of this cool night air.

....he does both iirc....anyways, i will never trust him.

Mark your car's been down a while, did you have something custom fabbed?

[BlackSheep]

True in some cases, especially for a turbo car when boost is determined by load and load varies with hills, gear, etc.. Not so much in an S/C application. S/C is always x rpm = x boost.. Taylor uses a load bearing dyno, the absolute best tool for tuning. He can load the car and tune accordingly, I believe he is the only tuner in dfw with a load bearing dyno..

[Mr. Hollywood]

I believe he is the only tuner in dfw with a load bearing dyno..

He's not. Jotech has a loaded 4 wheel dyno, which can be used on rwd. Cobb and RSI also utilize the Dyno Dynamics set-up.

Good to hear. Yeah, driving home from the Texas Mile is nothing new. I ran 205mph back in 2007....and backed it up with another 205mph run before driving it to San Antonio for a couple days, then back to DFW.

[Kumar]

who tuned the whippled-n20 gt from houston? He went north of 225mph right? I would start there if i were you mark.

217mph

I'll ask him who he used in Houston. Can't remember the guy's name.

edit: guess you already talked to Soroush

And honestly, I dont know anyone that is great with the GTs. There are still issues in my tune. I talked to tuners down at the Mile that have some cars that drive perfect and some they just can't get right. These cars seem to be temperamental.

[Kumar]

Mark definitely beat me that night. I had just got my car out of the bodyshop that day and had some issues. (If you guys want specifics, it made 810whp on the dyno in the trim I raced mark and going to cars and coffee that Sat, I found out i had 15psi in my Hoosiers)

I'm down for a rematch anytime. :)

[Fubar]

He used Nick at fast lane. As soon as I get my hunk of junk running again I will start calling.

[Rlhay2]

Perhaps one of the heavy hitters is willing to travel to Houston for TX2K10?
If so, perhaps they could be persuaded to stay an extra day to do some tuning.

[Fubar]

The beast, she lives. I finally got her back together. Now it's time for a little O-Zone abuse. I'll be out creating massive greenhouse gasses this evening.

Unless I break some other parts.

[citylightva]

Hell yean..!!! Enjoy it..!!

[Qship5]

I think I heard the GT all the way over in Fairview??? :eek:

Glad to hear it's back together and running.:thumbsup2:

[Louis]

Tunes do take a while. If you and Kumar both have issues, find a third GT guy, and fly in a tuner. Use a local dyno, spend the time and money, make sure you are happy with a road test AFTER everything is done, and be happy.

[Fubar]

I finally got some time on the dyno today. The tune from HPP wasn't bad at all. I don't think they looked at cruising A/Fs enough but the WOT tune was decent. We did find some ways to keep the car cooler and not lose any power (in fact we picked up a few ponies). So I think the majority of the tune is complete.

Now it just needs some street testing. :driver:

Mark, I'm sure you're happy to have the GT back on the road. Let us know how the street testing goes. ;)
