I recently tried to install the lastest update 9r02 into my u7142. After the install it said that my hardware was incompatible. I had no problem loading the 7r12 back in.

Also with the 7r12-d-fg I am unable to disable the rear o2 heater circuits. Everytime I try to disable them it locks up in the ...

turns out it was the cable thanks......

I am having the same problem with the u7142 with 7r12d. Saving the file with CMR and viewing it with dataviewer works.

No, I'm using the serial port on the laptop. I'm gonna try to find another cable and see if it works.

I have a U7142. Everytime I open CMR_Dat its acting like it wants to communicate but it won't pull the PID list. I have tried every combination of Com Ports and baud rates on the 3 laptops I have tried it on and in the predator. Anyone have any helpful information?
