I just got an OBDII to usb adapter and got the FORScan app on my windows laptop. I am wondering what are the most useful gauges I can pull from the long list of PIDs as well as other features of FORScan or similar programs. I would appreciate any help or advice, thanks.

 

If you are looking to log PIDs to determine the health of the powertrain (in alphabetical order):
EBP
EOT
FIPW
ICP
ICP DC (IPR)
MAP
RPM
TC Slip TFT

 

ICP pressure
IPR duty cycle
Engine oil temp
Exhaust back pressure
Voltage
CPS status
