So I have a 98 integra and i swapped in a b18c with a p73-003 ecu. Unfortunately I had to use my ls engine harness on the new motor and I have a feel that's where I went wrong. So before I spend a couple hundred dollars I want to make sure that will fix my problem. The car is in what I believe is limp mode, it won't go over 2000 rpm and it doesn't quite sound right. I made sure the connectors and everything matched both are obd2a. I actually tried the whole comp bypass because the ls harness has the connectors for for it but there is no sensor on the jdm motor. Nothing seems to fix it could really use some help.
