I monitor transmission temperature and engine temperatures.

thanks, coolant temp for sure, but the temp. on the 6 speed trany on the Workhorse chassis can not be monitored.

Fuel trims
Fuel trims a very important so you don't run into a lean condition I explain in this video. You don't want to see double digits
Also in the second video you don't want to over heat
Engine over heating alarm warning

X2 for measuring engine coolant temperature. If your Workhorse gauges are anything like the Chevrolet dashboard used on the P-30 chassis, the coolant temp. gauge is very inaccurate.

how do I find the codes/set up instructions? I went scangauge.com/support and was not much help. I'm I missing something or making something easy to hard? thank you for your videos. I will watch more of them as time permits.

I agree with Kevin, fuel trims would be first on my list because a lean condition will take out the motor and the fuel trims are an early warning.

both short and long fuel trims? banks 1 and 2? the Scan gauge short list has 4 banks for both long & short. doesn't list the MAF at all.

MPG (instantaneous) , AVG (mpg), Throttle Position sensor. Then row around to different settings. ie. Eng Temp when hot out.
This is how I get a true calculated 8.8 mpg including all gen usage, pulling an Accord. On a 35k lbs diesel. In mtns, hills, short trips, 2 lanes, city and idling.
My LBCU monitors another 3 parameters. ie. Trans Temp

For me the BIG ones are monitoring LF1 and LF2 at all times, due to the 8.1L's known failure to set a check engine light on fuel trim, as this can cause an undetected lean condition which could kill the engine. For me the other 2 spaces are normally set to read coolant temperature, and transmission temperature (note some model years with the Allison Transmission don't support reading transmission temperature through the OBDII port). On flat land I will often watch battery voltage instead of transmission temperature.
