  • $DF shift point higher that 6375?

    RPM THRESHOLD TO FORCE F31 TRANSMISSION UPSHIFT VS. STARTUP COOLANT TEMPERATURE


    ^

    sick of such a low shift point:P
    7k or bust :O
    how can i achieve a 7k shift point on df if this limits it to 6375....
    always shifts 1-2 at 6375...me needs higher to bring up the 2nd gear rpms
    sits at 4100 when it shifts to 2nd
    wanna bring that to around 4500

    You would have to develope a patch to have higher shift point.

    Most GM ECMS are limited to this 6375 RPM for most of the variables, the only one I have found that seems to be able to be set higher (IIRC I think I was able to go to 17000 RPM or so) was the rev limiter.

          i may have a workaround for ya Sil... just need to have the PCM compare against a RPM X 50 variable instead of RPM X 25.
          1995 Monte Carlo LS 3100, 4T60E...for now, future plans include driving it until the wheels fall off!
