Ok let me explain the build, I have a 97 honda civic and I am currently working on a ls/vtec swap and now that I am almost done idk if I should get a obd2 gsr ecu or swap over to obd1. I have never done a obd2-obd1 swap so I dont know how easy it is. Any help would be nice please and thank you.

 

Did you read any parts of this thread? Try t do some footwork.

Thank you very much I have read that and I am using it as a guide I just didn't get to the part about the ecu

 

What part aren't you getting? Mind not being so vague?

 

Best way to do it to get a P28 ECU, Hondata and a OBD2-OBD1 jumper harness, very easy. Then have it tuned. This way all variables on the head, block, sensors ect all all covered. If you use a GSR ECU it is best to use the GSR head and intake and you will need to wire a knock sensor along with all the other wiring needed for Vtec and the B series swap.

 

I didn't get to that part yet thanks though I just ordered the obd2-obd1 jumper harness. Thanks for you're help
