    Coyote TB tuning

    I need someone to help me fill in the blanks. I have a graph setup with ETC Effective Throttle Area vs. ETC Vacuum and plotting ETC Throttle Angle Error. I THINK this is setup correctly.
    My questions are:
    Is this graph setup with the correct PIDs?
    How do I use the plot to correct Predicted Throttle Angle?

    txcharlie, isn't that TB the same as the stock GT500 one used from 07-12? If it is (which I believe it is)...then just utilize the stock settings from a 07-12 GT500 and you should be good.

    Yes, it is, but you can see from the screen shot above that I have some pretty big errors when using the oem calibration.

    What tables did you copy over and did you verify/copy over all the correct axis' as well?

    Yes, the tables are the same as oem calibration. I used the GT500 values in Predicted Throttle Angle and Effective Area.
    The Roush tune TB calibration is slightly different than the GT500 calibration, but I experience the throttle issue less with the GT500 calibration. That's what I am using.

    You may have answered this before....what strategy are you using? Roush or based off stock?

    FSFROEA. I believe it's a Roush strategy. I bought the car with the Roush TVS installed with base 575HP tune and pulley.

    Ok forget the graphs for a moment. If I'm looking at a log, what do I look at to calibrate the TB? Using what source to correct Predicted TA table?

    Thanks for the info. Where there is Wheel Torque Error, how much do change throttle angle?

    You need sct to tune throttle

    What is HPT missing? I am sure Eric can expedite it if needed.

    I have everything in my strategy. Look at my first post. I had it plotting TA error instead of Wheel Torque Error. I have that corrected now.
    My question is how much to correct the Predicted Throttle Angle table when I record Wheel Torque Error.

    You need to plot ETC Throttle angle error over a histogram then apply the correction to the table and inverse.

    I'm not arguing, but I was told(by 2 guys) to plot Wheel Torque Error instead of ETC TA Error.
