Thread: Grid wont shift at higher rpms

    Default Grid wont shift at higher rpms

    Purchased a new grid system summer of 2016. Had very little trouble getting things going. This year I have not had the grid shift the transmission on the track 1 time. Went through all the basic settings and found the number of gears was set to 1 and I have a glide so I changed that. I can set the rpm low on a shop test and it will shift. I just tested at 3000 and 5000 rpm in the shop and it shifts every time. Don't want to test any higher on jack and stands. Is there a setting which would prohibit the shifting at a higher rpm? I am using the output switch in rpm mode to shift. Any help would be appreciated. I would quess that I am missing something obvious.

    On the output switch (brown/white wire) and the shift light (yellow wire) both required a 30/40 amp relay and both wires provide a ground signal.

    When using the output switch circuit make sure the rpm ON is what you want to shift at, and on the rpm OFF is 300 rpms higher than the ON. Also on this circuit it wont matter if the gear setting is selected for 1 gear. The output switch will work anytime its within its rpm range.

    Its not shifting while testing the unit or when going down the track?
