Torque Management not pulling timing with TC off. E40 GTO and 4l65e.
2bar OS, D1-SC (7-9psi), ID1050x, TransGo HD2.
Currently, no timing is being pulled on any shift while TC is turned off with the button. With TC turned on everything seems to work as expected. I want to pull some timing on the 1-2 shift and 2-3 shift with TC off. Am I expecting the wrong outcome with TC turned off?
I am not trying to make the shift any different right now. I just want TM to pull timing with TC off when it shifts, consistently. I have access to only what HPT provides for this OS. I would need some help if a parameter needs to added, but I have the ability.
I tried to make settings as close to stock as possible but nothing was working. These files are my latest attempt at making things work how I want.
-Brake Torque is maxed, but is not relevant for this purpose as far as I know.
-ETC Max is stock.
-For dramatic effect, I increased TM Spark settings 30%, increased Trans TM on shifts to 50% at 46 ft-lbs and 80% above 46 ft-lbs, and added values to the downshift TM table. I am not sure if my TM settings are counterproductive or not.
I have attached two tune files and corresponding logs related to each. The only change from #1 to #2 was a small PT shift speed adjustment and a WOT shift RPM increase in test #2.
- Test #1, Log #1 - TC On, Tire spin. 80% throttle for 1-2 shift and spin. Shift points adjusted for test #2.
- Test #2, Log #2.1 - TC On, No tire spin. Let off early.
- Test #2, Log #2.2 - TC On, Tire spin, hit RPM lim. (RPM fuel cut, ETC cut, Spark cut)
- Test #2, Log #2.3 - TC Off, Tire spin, RPM lim. (1-2 spin caused 2-3 shift, RPM fuel cut, then 3-2 shift, 2-3 shift almost hits RPM lim)
- Test #2, Log #2.4 - TC Off, No tire spin. (Early 1-2 shift to show long 2nd gear pull)
- Test #2, Log #2.5 - TC Off, Tire spin, RPM lim. (Similar to #2.3 - RPM fuel cut missed by scanner. (AFR spike and Delivered Torque dip indicate RPM fuel cut. Also heard/felt it happen))
Thanks in advance for any help.
