Im at my witts end trying to log through a/c pressure. There are so many posts all over about it but even HP is like ehh i dont know how to help you with a custom pid.....when in reality i told them a/c pressure PID7101 and then i told them what my voltage range was 7.35 0.00V 22.35 5V then i told them my offset -.7V but no dice does anybody here have this setup? it would be the same as loggin through EGR so if any of you could help me out id appreciate it thanks
