how not to lock the ecu??

  1. #1
    carnt remeber to be honest


    start the car let it run.
    remove the blackbox/immob near fuse box inside the car ??

    then stop engine
    remove ecu
    put new ecu in
    try that ecu and boom if it works do i then put the immob back in?


    if i wanted to put orignal ecu back in again. should i just leave black box out completely whilst pissing around with the ecus?
