Hey guys,
I have a customer trying to flash his 2018 5500 Cummins. He grabbed the details via the OBD section of scan and tune and we did our thing and sent him a file for his ECM. However when trying to license the controller it would come back as no ignition ($549) but you can still pull the details from the ECM so it is seeing it. Not sure if this is because the ECM is returning 2018 details and the tune tool does not know how to handle it?
I never had issues with the 2017 doing the same thing last year.
Any ideas?
