I want to log boost with my 3 bar OS and have been researching it on this forum but havent found alot. I have read that you can subtract the baro from the map and its pretty close so I made a custom PID using this function "[PID.11]-[PID.2340]" is this correct? Can I just log map and subtract 14.5 using this function "[PID.11]-14.5" ?
