So I just downloaded forscan. Slowly figuring it out. I think I know from reading here but what are the top PIDs to monitor?
Will forscan show boost pressure? I see PIDs for VGT % and such but no actual boost psi. Am I missing something?

 

Look for MAP sensor reading.

Boost is just the MAP minus the barometric pressure.

What you want to monitor depends on what issues you suspect you might have.

These are common ones:
ICP pressure
ICP volts
ICP desired
IPR% duty cycle
FICM MPower
FICM LPower
FICM VPower
VGT % duty cycle
MAP or boost
EOT - Oil Temp
ECT - Coolant Temp
TFT - transmission temp
Baro
EBP

If you are troubleshooting a no-start you want to see cam/crank sync, FICM sync, and rpms.

 

Thanks Bismic. I don’t currently have any issues, well besides needing a new oil cooler. Hopefully I’ll have that issue solved in the next few weeks. With this thread I am just looking for advise on what to watch going forward to hopefully stay ahead of any future issues.
