    K, the pinout difference is not LS1 to LS2. The cam difference is front cam sensor vs rear. The crank is LS vs 8.1.

    So did you repin the ECM to blue green?

    I'm not sure what you are calling repin, but I did swap wiring to cam sensor and to the crank sensor physical location, and then repined to the correct ECU location, i do not have diagram here. But i did spend a considerable amount of time on this very issue.

    A 99 ecm would have been a half meg red blue ecm. The file you listed on the first post is a 1 meg blue green ecm. This is what I mean by re pin, did you change ecms?
