i just realized that the guy i bought my car from said he "upgraded" the ecu, but i didnt know if i should believe it or not due to the fact that it had "altezzas" on it.... So today i was bored and decided to look at the ecu, i didnt take it out, just took the cover off of it and noticed p72. So is p72 OBD1?
TIA

 

p72 just means it's a gs-r ecu, it could be either obdI or obdII

 

FAK....how do i tell if its OBD1?

 

by the pins. OBDII is different. i dont have a pic, but im sure u can do a search on google.com and find some pics

obd1 has two rows of connectors...obd2 has three. or is it vice versa?

 

I think OBD II has three rows

 

i figured it out....its OBDII

what all is needed for OBDI conversion? just the ecu or will i need aditional parts?

 

an OBD II to OBD I harness and an OBD I ecu
