Yes every plug has been removed, checked and cleaned with electrical contact cleaner. Let me know if you need any other data logs. Thank you!

Here is another longer one showing engine data.

This is one of the engine parameters at idle with some part throttle pulls just to see the engine data. Question, should the ignition switch voltage be the same as battery voltage? It's a little lower.

Here is another one with key on, engine off. You'll see TCP # 2 voltage starts at .08 volts. This is because the fault code is active. If I clear the fault code, it will always be at .09 volts. Once the fault code is active, it always starts at .08 volts.

Here is one file with the engine running.

Wow just read through this whole post and what a great group of people. It's funny beacuse I was about to run down the rabbit hole chasing the low 5v ref on the TCP #2. I'm having a similar issue. I only have the TechMate Pro. I'm gonna buy the Diacom software for future boats. I have a 2011...
