Hi guys,
Been trying to set-up some gauges for my Ford Ranger, mainly want Auto Trans Temp for towing purposes.

I have set-up the Custom PID with code etc and get some numbers, although they mirror Cooling Temp which is probably understandable.

Problem is, every time I get in the car I have to re-load the Auto Trans gauge, Coolant Temp seems to stay as it’s not a custom PID.

Any ideas why it needs to be reloaded?
