I just fired up the new 5800 system with Engine Board. All of my sensors have been calibrated and are functioning, except EGT and CHT.

The EGT and CHT readings are jumping around between 200 to 250, with the engine cold, not running at 80* ambient temp. The probes are wired to the connector with the appropriate wire.

Sensors are new, full Dynon EMSKIT-L6F package.

How can I calibrate these?

Thanks
Frank

Dynon probes are most likely grounded probes which won't work with the AFS Engine Board.
