Repinning to the '7427 wasn't that bad. It started running rough and I never did get it smooth last night. I have a '90 G20 Vin K, 700R4, 3.08s w/ hd springs. APU1, G1 adapter, using BJLF, I started with $OD and tried $OE. Seemed to run a little better with E. I read somewhere last night that it's possible that I should use the $31. Any thoughts ?

Also, I kept having odd events. One at a time and sporadic. Like, it would start missing and my spark advance was reading 3578%, then my MAP would peg 100 kg and it would puke and die, and for about 30-45 seconds both injector cycles were around 600%. Quirks ?

I followed the pinout chart from here and thirdgen. I used a S8011 and soldered ECM feed to KS out. Besides inspecting the harness and renewing the ground connections, nothing else was done.

I'm headed back out to try the $31 and eat some pizza.
