Update, didn’t take the truck in today. I chatted with Chad Ivan on YouTube yesterday he recommend using the generic PID vs the GM PID in TorquePro app. Well from a cold start the generic value read 74 the GM value was 177, coolant and trans temp were 73-77 range. Do definitely a bad scaling of the value coming off the ECU in the GM PID. Shared this data with Banks as well. My truck is fine, drove it around this event temps were within 10 of the coolant temp.

Banks called me today, they are seeing similar readings on their test mule. They are analyzing the data and working on a firmware update to correct the value.

So I went back and watched some of Chad Ivan’s videos they show oil temps around 225, truck is headed to the dealer tomorrow. I have the iDash and the TorqPro app like Chad is using, 280-290 oil temps is way too high. Should only see a 10-20 degree variation between coolant and oil temps.

I’ve seen about 2 regen per tank of fuel with normal driving.

56 views and no comments? Well today the temp got up to 291, I’ll be calling the dealer tomorrow.

So I installed a Banks iDash yesterday and to my 2020 Chevy 1500 Duramax out for a drive today. I saw pretty consistent 280-285 oil temps with normal unloaded driving. I’m concerned this is rather high for an oil temp, ECT (engine coolant temps) were in the 200-217 range. Are theses EOT (engine oil temps) high, should I be concerned?
