Bcm/ecm security relearn issues.
So I got a new ecu, had a vin flash done. Installed it, saw the security light staying on. Read about the manual security relearn (although with a brand new ecm, i shouldn't have to do this i thought), however, once I turn the ignition on and wait the 10+ mins, the light never disappears. Do I need to do something before hand?
