2009 Cobalt SS with GSM1. I am new to using HP Tuners but started working with it. When using the scanner it by default was scaled to 255Kpa max when logging. I changed the scaling to be 300Kpa that would match the 3 bar maps that are on the car. But it still only logs to a max of 255. The gauge in the car does show 24-25psi on the tune I am running, but the scanner will not log higher than 255 Kpa (22.5psi). I have tried two different config files (Default imperial, and an LNF config by BYT).

I see also that PID additions, customization is possible for logging, but I cannot for the life of me figure out where to access this in the Scanner software to set it up or modify it. Can you direct me where it is located in the menus?

 

I figured out how to do the custom PID's. I have added some that refer to a couple other boost sensors that are listed in the software (and added them to the main table). I will try to chart a few of those and see if they show over 255Kpa (or 22.5psi).

If anyone does know this already, please still point me in the right direction to accurately log over 22.5psi with the scanner.

 

Found the answer over on HPtuners.
