    Default Throttle body silver to gold settings.

    Hello All. I installed a gold throttle body 90MM (from Silver 90MM) and am getting codes P1516 and P2101.

    I am looking for assistance in locating:

    1. Which two tables to adjust?
    2. Does anyone have the stock settings for a Gold 90MM throttle body?
    It would be great to have a starting point, eg % error and voltage range for a gold blade.

    I did find this info on the board:


    There are differences in the TPS signal output ranges between the silver and gold blade throttle bodies. Firstly, the ECM expects a specific correlation between the 2 sensor signals. For both the gold and silver blade TBs, TPS1 and TPS2 move in opposite directions. On the gold blades both signals have very similar ranges, while on the silver blades one signal has a small offset. If you have codes after swapping to a non OE TB, you would have to change the expected signal ranges or the allowed % error between TPS1 and TPS2.

    Secondly, the ECM correlates specific voltage values to % throttle opening. For example, if 4.0V is considered 100% and the blade hits the stop at 3.9V, it will not be able to achieve the desired 100% WOT position and P1516 will set (predicted TP != actual TP). A work around for this is to reduce the maximum throttle opening by a few % in the throttle response tables.

    You do not have to change the throttle area scalar when swapping between gold and silver blade TBs if they are both 90mm.




    Thanks so much in advance!

    I'm in the same boat i hope we can edit the voltage vs % opening for TB
    I have a problem with 102 TB with LS1B ECM trigering p1516 after releasing the pedale with medium boost but not at WOT

    My gold throttle body range at key on is Min 12.5% - 88.2% Max. Not sure if this helps. Need to learn how to add more pids on to V2. Lol

    Do you know if these are all of the parameters that your tuner had to modify, or is he having to make some CAX type adjustments too?
