im currently running a chipped p75 in my eg but when i baught it i made the mistake of buying it chipped to a 97 ls. i need to know if thats a problem or not its been shutting off after very low idle and while in neutral and when not giving it gas and thinking this is the problem need help please do i need to get it tuned to my motor or what?

 

how about just get a p75-a01 for a 94 95 integra ls/gs/rs and use it...

has the car been dyno tuned on the ecu that is in it?

Ya just can't simply run a ecu with someone else's setup on it.. yes it may be chipped and burned for a b18a/b but you cannot safely run it unless it was tuned on YOUR engine with YOUR set up.
