aight so i guess i asked the wrong question, i was under the impression P75 was a typeR ecu, will a Type R ECU hook up inplace of my GSR ECU, OR do they have different plugs???? simple question for someone who knows

ok, ecus's....
Is your gsr
obd1
or
obd2a or obd2b?

the itr ecu is obd2b only
SOO unless your gsr is obd2b, it wont work without a jumper

youre being too general with your questions............there is more than one answer

see thats what i needed to know, i have an OBD 1 GSR ecu, i was told from another person that i could buy there OBD 1 type R ecu and it would run fine, i then talked to another that said it was not possabe, soo what i got from this is, there is no OBD 1 type R ecu, even if i was running an OBD 2 car, it would not work because its OBD2b, thank you very much you have saved me some money

A P73-003 is a JDM OBD2a ITR ecu, and a P73-G01 is an EDM OBD2a ITR ecu.

All USDM P73's are OBD2b.

If I may ask, why do you want to run an ITR ecu? Did you change out your intake manifold, and you'd rather just swap the ecu than chip one?

Also, if you are determined to run an ITR ecu, you can always buy an OBD1->OBD2 harness for whichever ecu you choose to use.

Possibly. I don't know how much USDM p73's cost, but JDM ones run $200+
