Grego,

Thanks for your feedback. I chose BlueFire over VMSpec because of my ZF transmission, VMSpec only monitors Allisons.

My coach is still sitting in Missouri ready for me to drive it home. Fresh rebuild on the ISM, and the ZF transmission that worked flawlessly prior to the driveline swap. Currently, I've spent over $1,800 on wiring, but the engine and transmission aren't communicating properly. The ISM runs, but the shifter just blinks and won't go into gear. The electrician that wired the two ECUs together has given up. I've checked numerous online forums and the overwhelming consensus is that all that's needed is the two ECUs communicating and no additional hardware. If this is the case, I'm hoping that the BlueFire alerts will point me in the correct direction to resolve the issue.

I have the Cummins Insite Inline hardware/software for the ISM, but not the ZF hardware/software for the transmission. It's about $6k that I hope not to spend. The two communicate using the J1939 industry standard CANbus protocol. Fortunately, it's much more standardized than the CANbus protocols used by automobiles where every manufacturer has its own codes. I've purchased an Arduino CANbus reader, that will capture all CANbus traffic. Hopefully, between the BlueFire adapter that should capture all alerts, and the reader that will capture all the other messages, I'll be able to figure out the issues.

The alternative is $7,500 to have it towed to my driveway. I've got my Range Rover all ready to tow four wheels down, and there's room for a lot of tools. I just hate to make the trip to Missouri without everything necessary to get the coach mobile again...
