Hey guys, new to HP Tuners and the forum. But not new to the 8HP70's.
For the past 3 months I have been working on getting an 8HP70 to function behind the new Cummins R2.8 crate engine.
I have finally figured out the messages needed to get this transmission to function outside of a Chrysler ECU, and I am now getting into the tuning of the TCM with the HP Tuners.
We have a 8HP70 from a Dodge Eco Diesel with a Charger shifter.
So here is what I am trying to figure out, and correct me if I am wrong.
With the Ram truck the Gear +/- is just a request for max gear and not a true manual mode. Does anyone know what shift tables, or if it is possible to get the Ram 8HP70 to shift in a full manual mode? I would like the trans to hold what ever gear I am requesting.
Some pictures of what we have been working on.
