I have an rb25det running an apexi neo afc. I had it nicely tuned before blowing my motor up and now that its all back together and running, I am having issues tuning the new z32 MAF (new since the build). Really all I need to know is what IN/OUT values are used to identify the new MAF. I set to the values given in the manual (for the z32 maf, and rb25det ecu), but my full throttle is now at -22 at points that cruising is +31, just to keep the correct a/f on the wideband. If anyone has played with this combination of afc and MAF please shed some light. Thanks

From what I hear from very good sources on the board,get rid of the safc it forces timing down the throat of your motor and you will no doubt end up with another engine buuild on your hands
