    6r80 with 4c converter 2012 mustang gt with vortech v3 shift issues

    hi everyone my 2012 mustang gt with a vortech v3 supercharger and 4c converter is commanded at wot to shift at 6950rpm however it shifts way sooner, also it does some strange stuff when shifting it goes from 1st to 2nd to 3rd, then back to 2nd then to 3rd then to 4 in the quarter mile.


    this is what i gathered from comparing the tune to the log.

    data from log 2nd gear mph 28.06 rpm 5013.25 tune is commanding mph 37 550adc rpm 6950
    data from log incorrect 3rd gear mph 43.62 rpm 5668.75 tune is commanding mph 67 550adc rpm 6950
    data from log back to 2nd gear mph 51.36 rpm 5468.25 tune is commanding mph 26.822 625adc rpm 6950
    data from log 3rd gear mph 61.28 rpm 6462 tune is commanding mph 67 550adc rpm 6950
    data from log 4th gear mph 102.54 rpm 6180.25 tune is command mph 107 550adc rpm 6800

    I have a log however its too large to attach.

    Did you raise the setting to comp in the faster acceleration rate? Im not at my laptop and cant recall the name but its where the gear and tire setting is i think. I had a late shift tho.
