Yup...that's the one. I have the older model (AFC-2) on my '97. Wiring is
the same though. I can email you the wiring connections off-list if you
decide on that model.

Bernd,

Is this the one you have installed? Is this what I would use an an '93 OBD
I?

http://www.apexi-usa.com/product_electronics_detail.asp?id=260&pageNum=1

I could install it myself and get it close then take it to the speed shop to
dial it in? Or should I just have them do the whole thing? I built the
engine so mechanical and electrical work isn't a problem.

Thanks,
James
