Default I'll have it figured out very soon

Flyboy loaned me his H box to run in my car for back to back testing. I'll get it done this Saturday. I never got email or phone replies from APR. They probably don't want to waste their time or issue more license files without hard data.. like what I'll have this weekend.

I'm looking for somewhere I can do several fats runs without worrying about state troopers.

If the fats times vary more than a few tenths I may pay for back to back dyno pulls. The only problem is I'm not sure you can plug an ecu into a car sitting on a dyno and get valid numbers without allowing for adaptation time. Maybe do 2-3 pulls with each ecu?

If there's no improvement the only other explanation is maybe someone dropped their lunch in one of my apr stealth mufflers during fabrication.

Default The only reason to makes all the cars run from the same

ecu is so that it is easier for the tuner. There isn't an inherently faster ecu. The differences in the v1.2 H code were a result of the way the software was developed, not something with the ecu itself. I had plots of H and M code and the timing was clearly different between them.

APR Stg3 uses an RS4 MAF which is Bosch. As long as the software is on the chip, it'll work.

Default i wasn't clear - i was wondering about APR stg 3 cars

AWE and ASP both require conversion to hitachi MAF and I wasn't aware of what APR stg3 entailed

isn't that coupled with the greater reliability of the hitachi maf sensors?

APR Stg3 kit uses the RS4 MAF.
