Re: VSS Filter logic.

It seem to be like the problem I had with my 8 tooth speed sensor and wheel to decoder ratio of 1,410, the signal would skyrocket at low speed. I have posted a diagram of what I have done in the thread, it still works flawlessly from about 6 km/h and up. All that I have done made sense at that time,...

Re: Hysterisis issue on TPS load gear table

My pleasure, I love puzzles and to learn stuff. Beside we both benefit from improvement Well I went for another ride, it's just wonderful now, I have tried many settings, 10 km/h and 10% hyst is what works best for me, now I have full control of the tranny and engine on the same pedal, MAP is taking...

Re: Hysterisis issue on TPS load gear table

BINGO !!!! The TPS hysteresis works, but it's value is scaled up by 10x, I went for a spin and set speed hyst to a large value, and the TPS hyst to 1 (lowest value), it reacted like a 10% hysteresis value and downshifts from delta TPS. To save you some headache from reading everything I write, what'...

Re: Hysterisis issue on TPS load gear table

Ok I think I have it pretty much figured out. I have seen a huge improvement because there was no more gear hunting and the truck drove almost perfectly, but the TPS hysteresis never worked, it just acted as an infinite load hysteresis, but while punching the gas on the lower gear the rapid Speed in...

Re: Hysterisis issue on TPS load gear table

EDIT: Disregard these posts go to next post Removing the RPM checks did not make a difference, It was driving fine, except that it hung in second even tough I was swinging the throttle, same than in 4 th. If I break the speed hystersis, it will shift. I have tried to use a trans only project to data...

Re: Hysterisis issue on TPS load gear table

Thanks Lance, I will try 4,126d tommorow if the weather permit. As for the TTC lock temperature issue I have found it, the problem was on the INI file I have edited the INI for the no hyst below speed maximum and conducted a search for 5556 and have found the translate bin = 0.00000, I have set it t...

Re: Hysterisis issue on TPS load gear table

I have found a glitch on the full TPS gear table hysteresis, I did not notice it earlier since roads were too busy for 4 th gear long term operation. When the trans shift in 4 th gear, it will not downshift in 3rd, unless I break speed hyst or unless I hit the second gear bins, then it will (set to ...

Re: Hysterisis issue on TPS load gear table

Hi Lance, I have tried the test code, it did fix the reverse to Forward PC% spike, but it did not fix the TTC locking before reaching set temp, that said, below 42,3 there is no locking at all, the logic is there and working, but it operates 17,7 degrees too low. The formula to convert celcius to Fa...

Re: Hysterisis issue on TPS load gear table

I will add here a few small glitches that you may want to correct whenever you want, I caught two so far 1-TCC will lock under the limit temperature, the transmission seem to stay just warm for real (touch-O-meter), it will heat up just by staying in gear idling 2- Reverse line pressure is smooth si...

Re: Hysterisis issue on TPS load gear table

Wow that does it, it drives almost perfectly, just have some fine tuning to do, I had no gear hunt no low or higher speed glitches, I had to set speed hyst to 10 km/h and load hyst to 7% for my setup at least for now, WOT is unchanged, kickdown goes smoothly. The reason why I had to set a high speed...
