Boost Value Logging limited to 255kpa

[stodd347]

I have a 2013 Camaro SS with a 3 bar map sensor. Currently​, I am only able to see a Max of 255kpa in my logs.

I've read a few post where people have logged "low res" and created custom pids. I am unable to set up those parameters to log because they are not available for me to choose from. I cannot see them to select.

Please advise.

there should be 3 bar pid

You've likely reached hardcoded limit of ECM at 255kPa. Are you planning on making more than ~22psi of boost? If so, you may need to do some fudging and lose some fidelity to ensure the highest boost is accurate for fuel delivery.

Yeah, the tune is dialed in afr and timing related. Just started​ to enter boost above 22psi, all is good on the log. Just would like to be able to log boost that high, rather than looking at my boost controller in the run.
