I got EFI live from ppei. Then I try to install the tune it comes up with the code that the key is not on when the key is on. They even tried to tune in with my laptop and the tuner and it sad the same thing key not on. Any advice Would help me. Thanks
Sounds like you need the SGM bypassed....
2018 needs the serial gateway module bypassed (it blocks OBD-II port messages), speak with PPEI about how to do that is probably your best bet.
Edit: Funny Les I think we posted at exactly the same time.
Ok thanks they told me my truck was messed up and I needed to take it to the dealer. That they have done many 18’s with no problems and the problem was on my end to figure it out . So thanks for helping me with your product .
That is funny lol...Quote:

If you Google 'Dodge SGW bypass' you'll see there is people selling harnesses that bypass this module and allow you direct access to the CAN bus. It is a common issue on all Dodge, Chrysler and Jeep vehicles from late 2017.Quote:

Might have to flash a stock file from a 2015 in first....idk
That indicates the ECM still has the anti-tuning security active.Quote:

The software updates are posted here if you wanted to try yourself:
