    Ford 4.6 Supercharged-GT500 Throttlebody - ETC Vacuum

    Hey everyone, I'm new to Ford tuning and needing some guidance. I am trying to tune the electronic throttle and I am attempting to log a few channels. I have attempted to copy over the ETC values from a stock GT500 tune. For some reason, the ETC vacuum is flat lined when scanning and not responding? How is this value captured? Any suggestions on what the problem might be?

    The throttle response on this thing was horrible, and I have been able to make some adjustments to make it better, but still not good. I figured I would try to get the Throttlebody tuned in first and try to work on the Drivers Demand table some more. Does anyone have a graph layout or tips to adjust the Drivers Demand table?

    Also, I can't seem to get the LTFT's to work. I believe they are turned on. I have attached a tune file, and a scan.


    Any suggestions would be greatly appreciated.

    Thanks.
