Cm870 low boost high egt

find out what the ecm is complaining about during the derate. The fuel control state or cbl fuel state in particular.

it will reveal exactly the circuit in the ecm at any given moment that is in control of the power output, derates (hidden or otherwise) and all.

I would suggest an actual screen recording software like OBS studio to make live video of everything as it changes on the fly, instead of trying to use the spreadsheet recording crap built into CT.
