Apexi Neo tuning

[Jay99420aturbo]

Ok this 98 gsx has a walbro 255 fuel pump and rewire. evo 3 16g, evo 560 injectors, aeromotive fpr, injen intake, and an Apexi Neo.. and i was wondering if anyone has used this fc before and what there baseline maps were...

Set the Lo Map using the FT feedback from your logger. You only need to worry about the Ne points up to 4k. Then just copy the 4k point all the way to redline.

Mathematical correction for 560cc injectors is -19.6%, so I would start around -15% and work your way leaner after watching your timing curve. Have you taken care of all the pre-tuning maintence? Such as plugs, wires, timing belt (if needed), leak check, fuel filter, base fuel pressure, etc.?
