I have a 99 GTP with tons of mods.
My TCC Apply seems to have a mind of it's own.
Some days it locks up just like the tables say it should
Other days it never locks up
I did a scan of TCC status / slip rpm / duty cycle.
When TPS is at 0% the TCC status displays as: OFF
At 1% or more throttle the status changes from OFF to a few --- marks.
Once conditions are met for lockup, it *sometimes* displays "APPLY" and the silp factor begins reducing to ~20rpm and then the status changes to "LOCKED"
Other times, I can meet all the requirements of lockup (drive ~55 at 3% TPS) yet the lockup will not always occur... When it works, it works fine, but when it doesn't, it continues to display --- as if it is waiting for all operating conditions to be met.
There MUST be additional fields that not been discovered/unlocked by HPTUNERS? Anyone else experience this problem?
How sensitive is lockup? will it not occur if it thinks your air/fuel is off? Calculated load too high? ECT too low? Maybe it thinks it's more efficient to "not" lockup so it doesn't? aaarghhhhh
