I'm talking about the maf being wired wrong. And yes...even if it's tuned from a lap top..you have to open up the side of the e-manage, pull the board out and set the rotary knobs to the correct setting. There should be 5 little knobs with numbers on them. Yours is going to be set to 2, 0, 6. The last 2 knobs are for honda engines..so ignore them. This essentially is like a base map for your specific engine.
Then, in the parameter settings(this is in the software), you should have a pull down bar for different kinds of mafs. It will say air flow meter change above it. In your case..you need to change it to NS_HW2, which is for the z32 maf. Since the z32 runs at different voltages than the sr20 maf..it has to be compensated for.
