what is it and how does it work?
sounds like a bad thing

 

torque management is the computers ability to retard thetiming due to loads on the engine.i believe that it can retard the timing up to 30* when shifting under hard acceleration.but also i hear it is bad to remove it completely. but i have also heard that you can if you get a built tranny but i am not 100% sure on that one.maybe parish8 or big tex or someone with edit will chime in they know more about it. westers took out 75% of mine.

 

the factory put it in there to help increse the life of the tranny. on the 03's the computer can actualy close the throttle. my truck sounds like a stick when it shifts, i will see if i can get a clip of my shift with extreme TM.

on a stock truck it probably isn't that big of a problem but when you get more power it becomes alot more noticable, at the same time when you get more power you actualy need it if you have a stock tranny.

my advice, if you plan on doing a significant number of mods to your truck just plan on a built tranny and then completely get rid of TM with tuning.

 

see if you can hear this. turn it up! it is way louder in person. i can see on atap the throttle actualy closing.

thanx

 

can you fully remove tq with a built tranny? does it cause it to hit hard when you go into and out of gear or does the shift kit and built tranny take care of this? thanx.

 

here is a description i found a while back that is really detailed... this should answer all your questions..

Torque Management
Torque management is a function of the PCM that reduces engine power under certain conditions. Torque management is performed for the following reasons:
To prevent over-stressing the powertrain and driveline components
To prevent damage to the vehicle during certain abusive maneuvers
To reduce engine speed when the IAC is out of the normal operating range
The PCM monitors the following sensors and engine parameters in order to calculate engine output torque:
The air/fuel ratio
The mass air flow (MAF ) sensor
The manifold absolute pressure sensor
The intake air temperature (IAT ) sensor
The spark advance
The engine speed
The engine coolant temperature (ECT ) sensor
The A/C clutch status
The PCM monitors the torque converter status, the transmission gear ratio, and the engine speed in order to determine if torque reduction is required. The PCM retards the spark as appropriate to reduce engine torque output if torque reduction is required. The PCM also shuts OFF the fuel to certain injectors in order to reduce the engine power in the case of an abusive maneuver.

The following are instances when engine power reduction is likely to be experienced:
During transmission upshifts and downshifts
During heavy acceleration from a standing start
When the clutch pedal is released too quick under a heavy load, 6.0L only
When one set of drive axles looses traction while the other set of drive axles are not moving, 4 Wheel Drive only and in 4WD low
If the IAC is out of the normal operating range, except 6.0L
When the driver is performing harsh or abusive maneuvers such as shifting into gear at high throttle angles or shifting the transmission from reverse to drive to create a rocking motion
The driver is unlikely to notice the torque management actions in the first 2 instances. The engine power output is moderate at full throttle in the other cases.

The PCM calculates the amount of spark retard necessary to reduce the engine power by the desired amount. The PCM disables the fuel injectors for cylinders 1, 4, 6, and 7 in the case of an advasive maneuver

 

TqMgt sucks...it is pretty much there all the time you drive. WOT, part throttle, if the wind blows in the wrong direction...

I'd heavily reduce it on a stock trans. I am going to eliminate it totally with my tune as my trans has a TransGo and billet servos...so I am gonna give it a shot.

 

the transgo HD shift kit actually suggests that you totally remove torque management when you install this shift kit. this is the one that is going into my trany rebuild along with all racing materials. if you have a stock trans and you are modding. in my opinion leave the torque management alone untill you get it rebuilt or purchase a trans that will handle it. a stock trans will not last long with out it. the materials used by gm are defective. primarily the sun gear and sun sheild. this is what went on mine and created all kinds of havoc inside the trans. if you do have it rebuilt research the place where you are having it done, ask for refrences and also have them show some of their work. not every trans shop can build one correctly. you have to be picky. imo if he want sit down and discuss with me what i want done then im not using that shop. also after you have it done then you should take out the tqm and you will notice a whole new truck. it will run better then it ever has. i loved mine for the short time i got to drive it with out the tqm.

 

another adder to this. BigKID looked at my tq management with autotap today. Pred only removed a small amount. Then he showed me what tq management felt like. I had no clue. but i am still getting tq management when i thought i had eliminated most of it. so if anyone out there is thinking pred eliminates most tq, it don't.
