I plugged my blue ink tec eld into my data port on my 2020 KW t680 and now my tach is off by 4 to 500 rpms on the dash. The digital gauge is correct and the eld is correct. Anyone have a suggestion on how to correct this? I have switched the truck off with the Bluetooth in and with it disconnected but it's still the same
Tach is wrong
