I'm starting a Cummins engine swap into a 2008 F250, and I have a question about the ECM.
From what I understand the 06+ Cummins ECMs communicates through the Dodge tipm, and the tipm acts as a interface to the Cummins ECM that's on the side of the engine, the the obd2 port under the dash.
I've heard I'll need a tipm in order to get most tuners to work on a 2006+ Cummins. Is that the case with the HP tuner or can it talk directly to the Cummins ECM?
Thanks guys.
