i had the car running just fine the other day. then my new p28 ecu chiped and base maped on crome pro came in today. i hooked it up and the car started and wouldent idle. so i switched back to the stock p28 and it ran just fine idled ok. so i decided to try switching it back to the crome ecu and no start at all!!!so i switched back to stock yet again and no start at all. i checked i have spark and fuel pressure at the rail and power at the injectors. im a honda tech for a living and i have no clue. maby ing switch?any ideas
