TPS only reads 88% at WOT

E38/E40/E67/E92 Fan Logic

Speed Density tuning E78/E92 PCM's

Turned off your speed limiter but it still cuts out at 100mph?

Why is it no matter how lean I command my PE table my commanded afr doesn't lean out?

How the A6 TCM works

Read my PCM/TCM now no stability control? Read this

Why is it when I enter 50% enable does it not enable PE until much later?

Why is PE not kicking in when I command it to & rather gives me a 14.7:1 afr?
