I'm starting this thread for anyone with questions about trying to make a 6.7 Cummins run in a standalone application. I have been asked a few questions on the CM2200 bench harness thread but I think it is better to start a new thread to discuss things beyond what that original thread was for. I installed a 6.7 using a CM2200 into 92 F350. I also used a 2006 Allison with A40 TCM. The Allison TCM communicates through J1939 network on the CM2200. I currently do any tuning that the Allison needs with EFILive and use a CSP5 tune that I purchased from a local tuner for the engine. I have put over 45,000 miles on the truck since the install. Daily driving and fairly heavy towing is what I use the truck for. I'll try to help anyone with questions they may have doing a standalone install. I know when I started researching how to wire a standalone CM2200 there wasn't much out on the forums including this one. I am now in the beginning stages of tuning the engine myself.
