switching ECU's
Thursday, November 03, 2005 10:20 AM
Is there something I need to do when swapping an ECU?? I changed mine from the stock one w/a reflash, to just another stock one, and I get the SERVICE, CHECK GAUGES, and THEFT SYSTEM dummy lights and it won't start.

Passlock needs to be re-learned when you swap the PCM.
