I am having trouble with the 1-2 shift. I have recently switched converters and I cant figure out why at the track timing gets pulled and spikes back up multiple times before the shift. I have messed with the amount of timing pulled during the shift but nothing seems to help. I thought it might be spinning but with 1.59 60ft that doesnt seem likely. Although the mph starts to jump around just before it starts its repeated attemps to shift. I feel can the timing being pulled out but I cant figure it out. I have tried to raising and lowering the shift points but nothing changes it. I would appreciate any input as I have been messing with this thing for weeks.
