    Performance shift on a 97 Venture

    Ok maybe someone can point me in the right direction, I have the tables present on my ecm, but HOW can I hook up a switch to make them work? Ground triggered? 12v+ triggered? and what pin on the ECM

    I'm using a 058 97 Venture or Montana ECM in my Beretta right now and its on a 1996 4t60e transmission. I would like to get this setup on my toy car so I can have normal gas conservative shifts during driving but then when I toy around I can enable my high RPM WOT and part throttle shift points. So far the car got 27mpg on the highway with a rough tune going to NC last weekend so I'm rather impressed so far and I don't want to see a huge drop in that because of more performance orientated shift tables.

    Never mind, I found it.

    For those that care and can do this...

    in your bin edit the Shift_Switch_Type parameter to be a 1 vs a 0 to enable the Perf shift option, and then you just need to put a wire on Pin 21 of the Clear connector and run that to a push button NON momentary switch that will ground that wire out when on to enable performance shift tables.
