I had this issue when I first built my Mercedes. Use the command to measure the throttle (thmeasure, I think...) and monitor it while blipping it. I found that poor routing of the ground wire (and grounding it to the chassis away from the VCU) resulting in a lot of noise on the line. This led to the throttle signal occasionally going out of bounds. When that happens, the unit shuts down and has to be power cycled to come back online. I think it’s a safety feature. Check your throttle wiring, make sure it’s twisted, and ground it directly to the VCU. Avoid running it near the inverter or power cables.
I have emailed Thunderstruck about the issue. Sent them a picture of the config file and my set up.
As i took some pictures for them, i thought i would share them with you! Sorry they are from a gopro, all i had to take pictures with.
