Email your tune to me and I'll look at it.

Back on the dyno
So Tommy has the car back on the Dyno, he has never seen a car do this before. With tires rolling and the clutch pushed in idle is fine, release the clutch while in neutral and it bounces between 300 - 1500 rpm but, only when the tires are rolling. Performed learning for throttle and clutch, helped but, still has a slight bump in revs when clutch is released.

Tommy did his best to retune the car, but it still has a bit of throttle rev up when the clutch is released. But, he was able to increase the HP 20 to 25 from 1500 to 6400 rpm. The total on the mustang dyno was approx. 660 hp, engine rev limiter was raised to 6600. But the dyno sheet only goes up to 6400 rpm. From what I have been able to figure out that is approx. 760 rwhp on a dyno jet dyno. The car just never stops pulling, man I love this car!!! Last edited by Vicster; 12-01-2015 at 07:46 PM. |

I've been looking at it and right off the bat I see he didn't use the data from Injector Dynamics for the ID850's. Those are the injectors you have right? The offsets and min pulse width and other things haven't even been touched. That's the reason the ID850's cost what they do. Because they've done all the R and D to get the proper data and then they provide to you to use in the tune.

Injector flow rate is wrong. Short pulse adder table untouched Short pulse limit untouched Offset table untouched Makeup pulse minimum untouched Min pulse width untouched (this in particular would make it very hard for the PCM to control fuel at idle and low load conditions) Not to mention that he has set a commanded AFR of 10.8 at WOT to make up for how far off the MAF table and injector data has been set. Actually it is set to bounce back and forth from 10.8 to 11.3 over the RPM range. I would start all over.

Here the proper data that should have been used.

It is hard trusting my car to anyone, Tommy was so highly rated even here on the forum. I do all my own work, even designing my cam, that took me 2 years of learning and research. I guess I need to do this myself to.... THIS IS SO FRUSTRAITING!!! Thank You!! Last edited by Vicster; 12-02-2015 at 10:47 PM. |

I wouldn't drive it till you get a base tune in the car with the injectors scaled. You could wash the Rings if it is pig rich.
