Ok Stephan. that fixed the cut issue, runs pretty smooth, I can not get the LTC to work on the can bus 1. I have it wired directly to the M1 in can bus 1 high and low.. Any thoughts what I got wrong?

What do the Exhaust Lambda Diagnostic and Exhaust Lambda Collector Diagnostic report?

In the previous logging you have a Transmit Error Passive on CAN Bus 1, this indicates that the bus has an error on it as well, normally caused by either the wiring being incorrect on one of the devices connected to the Bus (High and Low swapped) or that there is a terminating resistor missing from the CAN Bus.

So with a bus line shorter than a meter, does it need a resistor? The LTC is next to the engine with the can lines in the loom straight to the M1. Here is the latest log file,

Yes, you will need at least one resistor between CAN Hi and CAN Lo
