TDC I am working on getting you some screen shots. I do understand what you are talking about.

take ur time i should be here....the main thing i need to know is how the tm settings work...or how the % affect the reduction or addition of tm...but i think brian probably has that down packed....Originally Posted by Andrew_99GTP
tell me what the stock settings are for the max turbine tq tcc locked and unlocked...if it is lower than 800 then you raise those values to get rid of tm...if it is higher then you lower those values...im going off of what brian has said

Does anyone know what brake torque limit is?
06-05-2008
should be amount of tq that is allowed while brakes are engaged...hpt does not have this...not to my knowledge anyway
thats the only thing that makes sense to me
shoot now that i look at it...if it were for that it seems the values should all be the same...not increasing....

Kind of what I thought but PT tables are hard to understand sometimes. I completely understand how to tune, what I have trouble with is figuring out the table descriptions.
Here is the description from the tm up shift table
Percentage of total torque reduction for 1-2 upshiftusing Performance pressure pattern
So in other words it is set to 5 right now, it will only reduce torque by 5%.

There the hell you are!!!!
06-05-2008
on the s/s you provided...did you alter any of the tables? if not did someone else?
06-05-2008
Just for S&G's, set everything from 4800 on up in 1st 2nd and 3rd to 600. That should cover your WOT shift, and see if it kills the kr. Again, it may not be good on the tranny...but that's a starting point if you want to begin to eliminate TM.
06-05-2008
I'm leaving that portion of TM alone until I get one of Trannyman's trannies.
06-05-2008
Next time we tune I plan on playing with all the TM files to see if we can get rid of the KR.
06-05-2008
yea i've come to the conclusion that lower numbers mean more tq mngmt applied...the reason that i belive this is because if you look at around the 4500-5600 rpm range the numbers are lower there than in the lower rpm ranges....
4500-5600 rpm's are most likely where you are going to compleate a high p/t or wot shift therefore more tq management is being applied....since the highest numbers i am seeing are 1020 i'd set them to there...it wouldnt do anything but minimize tm more...and if it breaks the tranny then it was on it's very very last leg anyway...and you may as well replace it...i dont see in any way that that would happen testing this tm to try to cure the kr issue
and im talking across the board but since the kr is happining in the higher rpm's at wot across the board really wouldnt be nessary to see if this is the problem...now to make it quicker it would have to be done like i said for sure

Here is the description that PT gives about the table(incase you couldn't read the small letters in the screen shot).
This table specifies the maximum allowable engine torque on an upshift as a function of engine speed.
06-05-2008
nope i could read it...thanks though
So basicly it seems like more tq management is being aplied in the rpm shiftpoint range and less through out the regualr rpm range
acording to the numbers anyway
06-05-2008
Well then in reading the description I would assume that the number in each cell is the max torque the engine can create during and up shift. This also doesn't make sense to me because 76 ft/lbs in 3rd gear at 6K seems a little low to me. Either way when I get a chance I am going to set the table to one extreme and then to the other extreme and see what happens. Might have to do this in the totally stock Regal though.
06-05-2008
You lost me there? What tables are you looking at?
06-05-2008
That should get rid of it...I did that when I was trying to go through the process of elimination. My hardest thing to deal with right now is keeping it from going into drivetrain abuse mode since I got my Alky installed. I'm not going to eliminate it any more until I get the new trans put in.
06-05-2008
Drivetrain abuse mode? Can you elaborate some more on this?
06-05-2008
ok so im a little late...lol

The lower numbers do indicate TM is being applied. It's the maximum torque allowed during a certain condition. If the PCM senses that more than this amount of torque is present, it will pull timing/fuel...etc to maintain that threshold.
Fortunately the first thing you should do is turn off the injector disable, so it will look other places....and keep in mind the PT only shows a fraction of the tables that are actually in the PCM. There are still many that you can't see.
