there's no checksum for any of them. And here's a thought. wanna measure more air flow? Just put two identical AFM's in parallel. Don't even have to hook them together electrially to the ecu. Just need equal split of air flow. So one unit will be measuring exactly one half of total. Now instead of x air flow at say, 3v, you got 2x air flow at 3v, but only 1x of fuel delivery. What to do? Adjust the injector constant so it
gives 2x of fuel delivery. Ya adjust agin for thos bigger injectors. Not a perfect idea but it a basic fuel system anyway. But looks to be a low buck way to get 400hp of air flow measurment instead of 200hp. What the heeeck. Noone has to do it.

Interesting, I wonder how many guys here are running 82-87 BMWs though 8)

Probably no BMW owners here. Just nice to post somewhere folks understand the concept of DIY eprom banging. Hard to fine same elsewhere.
