I just picked up a APEXi S-AFC. i picked it up used(but in mint condition for 199$ +shipping,) it came with instrustions. but i need some help... does anyone know what the optimal A/F ratio for a NA z32? or does anyone have any exp with this type of thing... i know that S.Services does the whole dyno tuning for about 100-125$ per hour(i think) havnt called them yet.

Ijust dont want my car to be one of those stories that a kid that just got his safc and blew up his engine or fukd up something really hard-core,well if any one can help thanks..

This will get you started (from twinturbo.net):

single MAF/single POP/singe POP ECU program (stock or JWT):
sensor no. IN=2 OUT=2
sensor cal. IN=1 OUT=1

You should be able to idle just fine w/ those settings. I wouldn't mess around with the fuel adjustements until you have wideband 02 access (dyno time).
