Ok I just bought a 92 MX-3 with the bp swap and I am trying to install the super afc but cant find a wiring diagram anywhere. Does anyone on here have one they can email me or post? Any help would be greatly appreciated.

that's not good

you really should get to a dyno with a wideband sensor if you wanna actually get any use out of that S-AFC.... ones' butt dyno is almost never accurate.

I hope you are going to get that S-AFC tuned with the proper equipment (i.e. wideband, dyno, egt gauge etc) and not plan on using the Autometer blinking lights A/F gauge as your guide.

I am still between two minds as to whether to go with the S-AFC 2 or the Greddy E-Manage but cant seem to find any MX3s that are using the E-manage setup.

Good luck.

yeah, you really do need a wideband and a dyno... the narrowband a/f sensors in our cars basically say lean, stoich, or rich, with next to no accuracy.

Yea i know this, im truely a v8 guy but ive been around enough to know that, right now i think its running really rich but i havnt got my air fuel gauge installed yet i just want to get it away from the rich side for now, I do plan on using the egt to get the final tuning done though, the guy helping me really knows his stuff too so i think im in good hands

don't even bother with tuning with a narrowband... it won't do s--- for you. It's only really useful for eye candy and making sure you don't go lean.

well to correct my previous post my car is running kinda lean so thats the only reason for installing the super afc for now... Im not trying to tune for lots of power and crap just to keep me from screwing up my motor. atleast till I get a turbo motor built up....LOL
