    Yeah my fuel rail pressure reads all wrong too. Sometimes it jumps up to 70,000 PSI or so....but thats on an LLY dmax.

    Can you guys please switch it over to show MPa, not PSI.
    Should show between 30 - 160 Mpa.

    Cheers,

    Just played the log file on my laptop:

    Scan build 312
    dll 454

    And everything looks good in Imperial. Perhaps the latest revision reverted back to what we saw during LB7 Beta?

    Looking at the log file I see between 30Mpa and 140Mpa which is quite normal. Looking at that in PSI it shows between 17,000PSI and 64,000PSI.

    Is that what you guys are seeing?.

    Cheers,

    yes. Thats what I see on my LLY. Strangley tho, the "fuel rail pressure" reads correctly in PSI. Its only the "actual rail pressure" and "desired rail pressure" that read wierd.

    Looks OK in PID "SAE.FRP_C"

    But PIDs "GM.FRPDES" and "GM.FRPACT" are incorrect.

    Didn't check yet, I was having a sleepless night. Will do it in the morning. I went through engineering school using metric but as soon as I got out in the "real" world everybody was using Imperial. I prefer metric just not used to it anymore.
