The P28-A02 ECU that I just swapped out was in the car when I bought it. So I am not sure how much it went for. The (supposed) P72 ECU I just bought off ebay, I paid like $200 for. I am not even sure if this is an authentic P72 or not either, since there is no serial number or anything. And the little label that was put on there says "JDM Integra GSR Obd1 ecu". So I really don't know what to do about all that. Not too many tuner shops here in Central Indiana that I know of either...
