    Different? Much different?

    A mate chasing one for his auto skyline to go with z32 nistune ecu. I only have one from an NA at home.

    You mean the atcu a/t gearbox computer? Shift points are different in 1st and 2nd gear from memory.

    Yep the auto computer. How much different are we talking?

    Anyone ever used an NA in a TT?

    The Owners Manual states:
    The automatic transmission is electronically controlled by a micro computer to produce maximum power & smooth operation.

    The differences in suggested maximum gear shift up speeds are related to fuel economy & vehicle performance.

    1st to 2nd: NA - 61km/h - TT - 68km/h
    2nd to 3rd: NA - 101km/h - TT - 113km/h
    3rd to 4th: NA - 151km/h - TT - 167km/h
    4th to 5th: NA - 196km/h - TT - 217km/h

    Keep in mind the differences in the diff ratios between a TT & NA.
    It is likely anyone that is running an automatic TT fitted with the NA diff could possibly benefit by changing to the NA automatic E.C.U.

    Na shift points are around 4500rpm in 1st and 2nd then 6k in 3rd and 4th, tt shift points were around 6k in all 4 gears.

    I had a tt ecu in my na, was fun going wot from the lights and worked perfectly fine. What box is he running in the skyline, didn't think any of them ran the tt re4r03a? I think I have a tt atcu around here he can have for cheap if need be.

    Fun fact, the r32 skyline was one of the first Japanese cars in the world to run a 5 speed auto gearbox.

    It's for an auto r33 gtst. Aparantly, when using a z32 ecu (for nistune purposes) it has to be matched with a z32 auto control unit aswell.
