    Default SAE.TP (Absolute Throttle Position) not reaching 100%

    I notice no matter how far I push the peddle I can't seem to get over 93.7% for the SAE.TP PID. The same seems to apply for the default supercharged Monaro data logs that come with EFILive (didn't go past 90%).

    What should I look for to get my throttle position to read 100% instead of 93.7%?

    What is the TPS 'voltage' reading at full throttle?.

    Also check for mechanical obstruction.

    Yup, what he said.

    Mine was only able to go 93% until I did the bump stop mod. www.installuniversity.com, lsx and install docs/ bump stop mod

    Guess what, that car had an issue with the throttle cable, it was only getting to 90% at the blade it was discovered :oops:

    Once you tell us the voltage the TPS is reading that will give a pretty good indication of just how far it is opening.....also, what the TPS voltage is when the throttle is shut.

    Bugger, setup BB logging and went for a drive today (no laptop available) but it didn't record any logs. Had set it to validate pids instead of log new data. Will do it in the morning on the way to work.

    Went for a drive and this is what I got.
    Max 93.7% TP @ 4.1V
    Min 0% TP @ 0.7V
    SAE.TP and GM.TP PIDs show similar results, 93.7 and 94.1%

    Is this something that can be modified in the PCM or is it more likely to be a problem with the throttle cable or similar?

    Looks like the cable. 4.6 v is WOT IIRC.

    If it is the cable should I be looking at trying to tighten it somehow? I assume (unless it is the bump stop) that the throttle cable isn't pulling the throttle open far enough.
