i love rice

i started running a chipped p72 ecu on my h22. the ****** cel comes on only when i drive it cold and not hard. i shut my car down and it doesn't come back on. I checked everything the book said to, i was runnin 38psi and turned it to 46,then 52psi. my car never did this before. i was runnin a stock jdm p72 before i traded for the chiped one. i also tried a p30 and it did the same thing. does anyone know whats going on? any suggestions would be great, besides the obvious getting a new ecu.
