Hi, just signed up to ask this question.
Im planning a high HP NA build for my E28 M5 with a S38 engine. I want it to feel like a more modern engine, in terms of bells and whistles. Ive got all the mechanicals planned out pretty good, but im searching for an engine management that meets my requirements, they are as follows:
Downshift blip. (revmatching)
Peak and hold injector drivers.
Fully sequential injection and ignition.
Possibility to view live data on android device - Oiltemp/pres. EGT, AFR minimum.
Closed loop lambda (O2) control.
Would also like recommendations for what sort of actuator to use to control the ITBS.
