Just did the b18b swap in my sol and I installed the p75 ecu I got from ebay. The check engine light is on and when I put the paper clip in my plug to shoot codes the light just stays on not blinking. I would guess bad ecu, what else could it be. Is the ecu self grounding?, when I hooked up the new ecu I installed it exact opposite from old p28, I don't remember a ground wire.
