Tuning the 2011 GT

Don't know where the sensors were placed.

We have found some very interesting behavior related to the car commanding itself to stay stoich (14.7:1 for E0) at WOT and are still tracing down when/why this happens. This is an example as to why these tunes need to be done correctly and not just a blanket timing adder.

That is interesting Ken. Our car has not done that at all during any of our tuning over the past two days. Its pretty dead on 12.8 WOT/WOP each and everytime. I'm curious as to whats causing that on your car. Hope you can nail it down.

Keep up the good work.

It's built into the calibration. As you can see the graph above is doing the same. You just haven't hit the requirements to go into this mode.

Thank you. Do you know the weather conditions when the pulls were made? How hot was the car? Did they have proper fans on it?

BTW, you keep saying your car, lol. This is multiple cars and it's part of the calibration to do this. Just wanted that to be clear.

Sorry I thought you were referring to the one car you have had on the dyno in the video's, I didnt know you were talking about several cars having this issue.

Maybe its a problem with the calibration itself. I know Ford has several calibrations out there. Mine is an HYZ6 if that helps. In the calibration that I have here for our car I cant find anything that would cause what your describing and even when we did have an issue with the MMR intake and the stock tune airfuel stayed exactly the same as with the stock airbox.

Strapping ours down to the dyno today again for tuning, if anything funky happens I'll be sure to report back.

probably mid 80's raining outside with 90% humidity (Houston, TX)

Didn't have a fan in front but let the car cool down a good 30 minutes before the run.

Ok thanks. that helps alot

So I am confused have you gotten the car to run at normal afr or is your doing the same thing mine is?

your car isn't always doing that, it just seems that way on the dyno. It's part of the calibration from Ford. I'm not a 100% sure what triggers it but I have some ideas. Still working on it. The cars I've done so far all do it from time to time.

Ken, have you had a chance to do some power enhancements yet? What kind of gains should we expect to see with the Diablo software?

All runs were done with approx 195* ECT and 100 ACT
Ambient temps were in the 95-102* range

Stock baseline
370 rwhp and 329 rwtq

Diablo tuned
392 rwhp 377 rwtq

That a peak to peak HP gain of 22 rwhp
Max HP gain was 47 rwhp at 5300 RPM


Max Tq and Peak Tq gains were both 48 rwtq at 4400 RPM

Nice numbers Ken! I'm curious as to whether you guys have been able to do any tweaking with the VTC and if so, has it made any difference?

cost and datalogging. does DL include a/f ratio in real time?
