Who here on this forum knows the ECU/PCM/ECM component intimately ?
I would like to know why you need to disconnect the power from the ECU/PCM/ECM for 15 to 20 minutes for it to lose it's memory/settings.
Does it have a temporary backup battery(capacitor) that keeps it's charge for 15-20 minutes to perserve the ECU/PCM/ECM settings during a normal battery change ?
Just reading.....
