I actually have the file for the adapter to mate the two (Motor to Trans) together. Working on flywheel as well. We can tune the TCU with VF Tuner as of right now, but they are the only ones able to do so. Even if we could use the G5 to piggyback stock ecu for the 2urgse, and VF tuner for TCM, we'd be making some good headway while trying to figure out the TCM data. How are yall testing the 2UR now? Is it just a complete custom harness and more for a race setup and not "street"?
