just like it says, my buddy picked up a 91 (i believe) si, and we're swapping a d15b in to it. i believe i figured out the dizzy issues, now i just need to know what ecu to run and what te .bin to use for that engine (stock for now). i'm very unfamiliar with obdo wiring, ecu choices (just slightly familiar with the more popular obd0 ecu's), i here about the ps9, would that be my best option?
