S-afc & Gsl-se ?

Does anyone know if the Apexi S-AFC will work with the GSL-SE computer? I looked on the apexi website for the wiring diagrams and it only listed 86+

Has anyone tried it?

Don't think so, kinda brain dead (12hr shifts this week) but I think the GSL-SE AFM system is 5V based and the 2nd gens on up are 12V and the SAFC's modify 12V signals, I looked into it years ago, and I'm pretty sure thats what I came up with.

backwards, gsl-se is 12v and every other car is 5v.

i dont think it will work either.

Supposedly the AFM runs out of airflow at the same time the injectors max out. (About 200hp) So if you go screwing with it, one or the other will limit you.

I haven't played with GSL-SE stuff, but I am looking for an OEM flapper-door type EFI system for adapting to a project. For what I am planning, carbs will suck. The GSL-SE system looks nice.

I tried to hook up the AFC thing and it doesn't work. It's probably the voltage thing.
