EcuFlash Part 2...
Well sorta...
I thought this last weekend would have been cooler on the Gruppe-s dyno then 2 weeks ago. Boy was I wrong.
Hot as hell is the only way to describe it.
I got back on the dyno this last weekend to fine tune my 91 octane tune with ECUflash. Turned out that I didn't need to do a thing to the tune after my last round of street tuning. The tune is solid as a rock. Super consistant pull after pull even in a 90F+ room filled with stuffy exhaust fumes and less air flow then you would get on the street/track:
So I went straight to working on my open-track 100 octane tune using ECU+ on top of the 91 octane ECUflash tune. More boost, a little bit more timing and 11.5 AFRS, consistant again:
The car is a freaking torque monster now with 100 octane, 25psi spike dropping to 20 psi up top, check the torque curve difference between 100 octane and 91 octane tunes:
These are all ECU+ dyno charts that where done off logs from the car on the gruppe-s mustang dyno. I will get the actual mustang dyno print-outs later, Mike and I where in a rush to get home.
I will also try and do some actual street pulls with ECU+ dyno soon, they usually read a little higher with the additional airflow. I also can't wait to see what the car will do on the dyno on a cooler day.
I'm really happy how easy it was to get the car super consistant with the EcuFlash. Pull after pull after pull..

The 100 octane tune was about +5 within whp and actually a bit off in TRQ, in normal temps day its much closer matched to the mustang.
This mustang always reads lower TQ numbers then HP.
Mike is gone at mid-ohio this week but when he gets back I will get the printouts.
I don't really tune by the numbers anymore, more the curves and consistancy. Just looking at that torque curve spread on the 100 vs 91 tune is yummy. The car is just a tad fun to drive on 100 octane now.
