I'm curious which pins you swapped on the N/A harness, not the VDI pin at the ECU, but IIRC there are two pins that need swapped further up the harness on the two plugs that attach to the dash harness. I've got two spare N/A harnesses and compared them to my modified harness...I can't find any wires different.
I went with the 1.7 at first, and it was fine, but I wanted a little more control and its only $350 to upgrade. I've been able to add fuel and (subtract fuel for idle) and it idles and runs great. turnaround is very fast. My next upgrade is a BNR stg1 (mainly for the ported wastegate). a pull from low rpm in 4th creeps to 14psi, which is where the map on the stock ecu stops. In the stage2, I actually have the injectors go almost full open if it sees 14psi.

I didn't change any pins anywhere... though I'm not running a knock sensor or boost control solenoid. All the others match up to their respective turbo pins.
