Smallest digital GM MAF sensor?
 

GM people, I need your help.

I'm trying to find the smallest digital (frequency output) MAF sensor that GM uses on their engines, which will probably be a Hitachi unit. I haven't found out much yet, but it looks like the 3800 and larger engines have used them. Does anyone know of anything smaller (less than 3800) that uses a digital MAF??
Delphi units would work also, if they are small too, I did see that GM has used both Delphi and Hitachi on different cars..

This is for a completely different (non-GM) engine, I don't care about how anything mounts or anything like that, I can make anything work for what I need. I just need a small MAF to get the best resolution for a small engine.

Non-GM digital MAF sensors would work also, I'm not sure if anyone but GM uses digital output MAFs though.

Thanks for your help!
