OM648 swap into a w123
getting the tune on the transmission really dialed. It is always amazing how a few changes in shift points and it just changes the way the car feels. It is also fun that I have a client with a 2006 E320 cdi that is running the tcm-2800 in his car and to work on the tune remotely and share the info from two different cars but same engine and transmission. Comparing logs between the two and what I feel on my end and then taking that to the customer file.
