    Editing "I" and "L" settings - 4t45

    Anyone know how to do this? It feels like the pressure is based off the pressure tables but i have no idea how to do the shift points. I see D1 and D2 tables in the shift speed tab but it really doesnt correspond with what the car is actually doing.

    I've toyed with these setting a bit on mine. Nothing I seem to do really makes much of a difference. I have not spent too much time messing with it though. It seems to obey my set shift pressures and shift times I've set but it strays from my TCC duty cycles table when in "I" or "L"

    Take a look at the safety shift settings for D1,2, and 3. Thats what I was going to start messing with next.

    Same here on pressures and times. I wish i could make L gear not shift and just hold 1st.
