Hello I have a n14 celect plus engine in a 1997 kenworth t800 . Was thinking of buying a spare Ecm I saw for sale . Are they plug and play or is there different models of Ecms . Thanks
Programming will probably be different based off the CPL # and the user settings. Cummins can probably copy your current ECM program/settings and load it all into the new one.
I was told they are plug and play as far as the motor starting and idling. You need to have the ECM software calibrated to your specific motor for full function of parameters. The hardware is the same. The software is not. In my learning years. I had an ECM go bad during a trip. I removed the ECM went to Cummins bought new ECM. Took it back to truck installed the new ECM. All fixed, I thought. Turn key, nothing but a motor turning over but wouldn't start. Back to the Dealer I go, fully aware they sold me a bad ECM. NOPE. The ECM I bought was as good as a brick, I didn't have them install the software and parameters. That cost an extra $300.00 Make sure you buy a CELECT + ECM not a CELECT ECM.
Check If the labels of the engine ecm and the spare one show the same year and model. I think those 1997 trucks dont use immobilizer. In new trucks is a little more complicated because all modules on the truck are registererd under the same VIN number and a reprogramming is needed.
