Interesting thread. I wonder why no one is going the MAF route? Why no one is getting a adjustable (fuel and ignition) to adjust over the Motronic to match the engine 100%?

The stock AFM is rated at around or less than 1000kg/hr flow, meaning it'll max out at relatively low HP. Under boost it'll generate 5V at lower RPM (regardless of position).

The AFM has a built-in Intake Air Temp (IAT). The IAT is used by the DME for calculations (fuel & ignition). This must be addressed and handled correctly when relocating the AFM to the pressure side (much hotter air).

I'm converting my 930 to EFI running a 3.2L Motronic with a blow-through MAF and Wasted Spark. The Motronic I'm using is enhanced to accept and interpret a MAP sensor to alter ignition based on boost. So the system wil have both MAF & MAP. If anyone interedted, I can document the conversion and share a few pictures as I progress.
