i just bough an ls with a gs-r swap an am not sure of Wat kind of ecu does it has i made a little of research but am still stock i cant see to find if is a gs-r like p72,p73,or pr3… here is the number of the ecu===37820pr3901=== am not even sure if is a obd1,obd0,obd2… plz if some one have some info ill appreciated…:hmm:
Its a PR3.
Is it plugged into your stock harness, or is there a conversion harness being used? PR3s are JDM/OBD0 ecus… So they would plug straight in to a '90-91 Integra.
Next time use a better subject… Not just “ecu??” Use the subject as a way to tell us whats wrong with your ecu… A title like “What ECU is this?” is a much better title. Its not just a suggestion, its a site rule.
mybad… but thanx i have not cheked it yet but ill let u know if it is a conversion harness…

Pr3 is obdo or obd1
i have a PR3 OBD1 in my 92 gsr now .
D’oh, you’re correct. However the OBD1 PR3 ecu from the XSi is usually uncommon. But the year of OPs car (and if it is using a conversion harness) would tell us what OBD the ecu is.
sorry guys i have not had alot of time to chek the car out cuz i work everyday… sowhen eve i get 5 min ill look at it… but thanx for all the help…
