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.

The Hot wire mass air flow sensor does not have a mechanical flap. It heats a wire, and measures the amount of current necessary to keep the wire at a precise temprature. It doesn't care if the air is flowing in or out. It does not matter if the air gets measured twice. The software can be written to take into account the reversion pulses at low speed.

Or like on my Ranger truck, you move the MAF 3feet away from the TB connected by a tube. I just changed the MAF (60mm) and it was only $70 so they are not pricey. I would think this is the way to go cuz its pretty simple EFI which is good.
