Torque Management & SCT
I have read in several places where the SCT tuner does away with the torque management. What exactly is this and why is it good to get rid of it? I'm getting ready to do a good bit work to my truck this week (1997 RAM 1500 5.2, 4x4). I doing the plenum (from Hughes), the Kegger Mod, timing chain, magnaflow cat, O2 sensor, map sensor, and water pump (along with a few other minor things). I'm sure these will do wonders for my engine. What else will the SCT tuner REALLY do for it? Don't want to waste nearly $300.00 if its not going to do a whole lot. Appreciate the great discussions.

SCT tuner from hemifever has been proclaimed THE best bang for the buck mod. Even on the 87 tune, it will be better than stock.
Torque Management is Dodges way of gimping the engine so it doesn't tear up the crappy transmissions they put behind them.
Basically, an engineering shortcut for substandard parts elsewhere. (chiefly, torque converters.)

No, Torque management is there to soften up the transmission by letting the clutches slip. It gives you that very nice smooth shift like your Grandma's Buick. If anything, it reduces the life of the transmission.

Transmission were weak from the factory. Trans longevity depends more on driving style, and usage than anything else. If you are constantly hammering the gas, or hauling around large heavy objects, trans life is going to be shortened. If you drive sanely, understand your transmissions limitations, It can last quite a while.

So, the torque management actually hurts the transmission. Correct? Doesn't make sense why they put it in to begin with.

Doesn't make sense to use a manifold design that you KNOW FOR A FACT is flawed either.
Doesn't make sense to use a dash cover that you are well aware is made of sub-standard materials either.
Doesn't make sense to continue to use a torque converter design that you are also well aware is not up to snuff.........
Torque management was designed to spare some parts, at the expense of others. It was a bandaid fix that made the corporate beancounters happy. That's it.
And you wonder why Chrysler filed bankruptcy?

Here is a couple reasons for torque management
1. Comfort, softens shifts to a barely noticeable shift by reducing torque when shifting...in our trucks it dont really make a difference
2. traction, in low traction situations a firmer shift may cause unwanted wheel spin....our trucks really dont make that much power and unless your an idiot it wont bother you.
3. originally to help extend lifeof tranny, but slow shifts cause clutches to heat up more doing the opposite
Reasons to remove
1. Full power at take off and through gears
2. firmer/faster shifts less wear on tranny
3. lets motor run more efficently

I've read otherwise....
Torque management systems limit the *engine*, by cutting torque output, to allow the transmission to shift. This saves the transmission. Most torque management systems on newer vehicles retard the timing to achieve this. They can, in some cases, limit fuel supply during shifts (fewer/shorter injector pulses, etc). The torque output of the engine is essentially cut off for a short time, and restored. This would give you that "grandma car" shift feel, but due to a different reason.
The main reason most people feel a dramatic improvement when they install an SCT Tune, is because it gets rid of TM. This causes the engine to produce full torque during the entire duration of a shift. So when the transmission clamps down on the clutch pack, it's clamping down when the engine is producing gobs of torque, thus giving you the rush of power you didn't feel before when you had TM enabled. Making it feel like it's shifting much faster and firmer.
Think of it this way: Suppose you have a shifter kart (a go kart that shifts with a clutch). This shifter kart is setup with a switch on the clutch pedal that retards the engine timing every time the clutch is pressed. So, every time you press down on the clutch pedal, the engine isn't able to produce it's full power until the clutch is released. This would be a very basic TM system. Now, suppose you completely get rid of that darn switch! You think you would notice a difference from before and after? Yes! The shifter kart would feel much faster, even though the engine makes the same power as it did before.
Our PCM's cant control shift pressures/fluid volume, that's where shift kits come into play. If your transmission is slipping between shifts, it can't be fixed using a tuner (in our case).
