    Why, yes I do.

    AFR heads, Superram, LPE219, 30# injectors, 10.5:1 in an '86 Vette. Originally this was set up for street/strip with plenty of runs on street to dial in timing using oil temp with 89 octane. Strip usage resulted in poor launches due to insufficient traction so adjustments were made to delay PE and driver was instructed to ease into throttle and stay below 1/2 up to 2nd gear then ramp up to 100%.

    Yep. Spent a few years working with the MAF but after I found out the owner was cranking fuel pressure 6-8 psi over stock on track days I convinced him to let me switch to 7730 / SD.

    Hope it works for ya.

    This seems to be working, but looks like BLMS are locked or it never allows for Closed loop?
