ok i got my engine (b16 sirII) from e bay. the guy who sold it to me (streetdragz) sent it to me with a PR3 Ecu. I sent him the money ($2300) expecting him to cover the shipping (won the auction for $2000) he keeps the extra $300 and sends it freight collect. Now upon other problems with the engine and him sending me the wrong stuff, i gave him negative feedback. he is quite upset about the whole deal and now is not sending me back the extra $300. Now here is where i need a ECU expert. he claims that the peticular PR3 he sent me was indeed an OBD 1 ecu. he claims he hooked it up to his 95 civic and it worked fine. i need to know if indeed that Honda made some PR3 ecu's that were OBD 1. he is claiming that since the ECU was indeed OBD1, he went out and actually "upgraded" the ecu to the p30. so in doing so, it cost him $350 upgrade fee and plus he charges a 35% restocking fee, so if anything, i owe him money. Please someone get back that knows all about these ECU's. i have already looked up the the pr3 on the reference and it shows that it was indeed a OBD 0 ECU. i need to know before i sue the shit out of his ass.
