Man, I give up. I can't find it. Using HPTuners on my '02Z06 vette but can't seem to find a PID for oil temps. Am I just overlooking it?

 

I don't think oil temp is something the PCM monitors on C5s ... they monitor oil pressure (while the F-Body Does not) but if you want oil temp you'll need to use the EIO and an external 0-5 volt sensor (not sure if the output of an autometer gauge would do it)
