I was just thinking about how all the aftermarket injection systems all use vacuum signal which can cause problems with wild cams. How come nobody is using a Mass Air Flow sensor? It can't be that complicated. Famous last words.

A Vane Air Meter... (the L-Jet AFM) is lousy with a radical cam. The reversion pulses foul up the readings back to the computer. Same goes for the sensor plate on CIS.

D-Jet is a MAP sensor system, and it gets fouled up by the low vacuum.

You can use a Hot Wire MAF. It doesn't get screwed up by the reversion pulses (no moving parts). Hot wire MAF can be retrofitted to a Motronic system.

Or use the Alpha-n system.
