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..

Wow, very nice numbers.

 

out of curiosity, how comparable were the numbers from ECU+ to the mustang sheet?

 

On 91, the ECU+ numbers are spot on in TQ and about -10whp off in peak HP. Remember it was very hot and stuffy and my car never makes good torque in those conditions. I was about 19-20wtq off of my usual.

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.
