Tune Feedback Request

Unread post by NotchAbove »

Hi All, New to the forums. I wanted to see if I could get some feedback on my current tune. I have been running this tune for 11 years now. No real issues, but I would really like to get some eyes on it.

I tried to stay as close to the stock A9L2 bin and work from there. Mods are in my signature.

Tune Info

Forced OL / Adaptives Off
MAF - 90mm Ford Lightning /Cobra - Curve Reduced by 3%
BB302 Injectors - Adjusted High/ Low Slopes
Base Timing - 10* (FN111 - 31 max Advance)
Base OL Fuel - Goal 11.5

I hope to get some current datalogs this coming weekend.

Updated tune and datalog. Changed to E10, and 90LMAF Stock Curve.

Few conditions noted. Running on the rich side. Average of 5% over Lambse at WOT. At Cruise average of 12%, and at Idle 10%.

BB302 High and Low as per Ford. As Noted 90LMAF as per stock LMAF curve.

Car has issues returning to a clean non surging idle.

You have to use tunerpro with the A9L2 as there is no BE definition file for it.

Otherwise you could be changing something entirely different than what your expecting.

Best to post tunerpro datalogs as well since tunerpro automatically populates all the errors for you. That way instead of going though the log you can just look at the errors.

Appreciate the response. Trying to get TunerPro RT to work at the moment. Followed your steps. When I load my bin and look at any of the scalers that have been updated, they are all incorrect. Not sure how to get it to see my current tune bin that I loaded in.

Thats what its supposed to do.

You have to set the injector high slope to your actual injectors value for the actual base fuel pressure your running.

Then everything will be correct and show your actual values that should look sane to you.
