Audi 3B engine is similar to VemsAudiAan, so procedures are the same, but
- the [relevant] pinout (file, or spreadsheet column) must be used due to pin differences
- eg. flyback is same mot55/pin37
- but trigger pins are different, and most outputs
See Audi3Brelay
Ignition output(s)
- Either just 1 igncoil can be used, with distributer
- or custom ignition output mapping for passive coils, or active coils
- Audi POS power output stages + passive coils together are effectively "active coils", because the ECU can drive with logiclevel positive-active signal.
Eg. 4 stepper outputs (possibly with 100 Ohm protection resistors) and a logiclevel ignition output on an extra (eg. EC10 flyingloom) connector possible for 5 COPs if requested.
Fuel pressure regulator
- target pressure might differ from AAN
- eg. 3.5 bar instead of 4 bar FP means sqrt(4 / 3.5)=1.069 so 6.9% (7%) more fuel injection PW required, consider this when tuning (or when adapting borrowed tables)
- remember the first 1.4msec of the fuel pulsewidth is just to get it open
