Torque Management ?'s

[rearden82]

From my understanding, torque management typically involves programming the PCM to reduce engine power during gear changes. This makes the shifts feel smoother while also reducing wear and tear on the transmission. But aside from when the tranny is in between gears, full power is available at all times.

Based on the Edmunds review and other reports, the new GM pickups apparently run in a "reduced power" mode all the time unless you floor it for more than 4 seconds. Most likely it's for enhanced fuel economy and/or drivetrain longevity, but I don't know for sure. Regardless I think it is BS, since the engine is basically crippled and putting out far less than its advertised power in 99% of real-world driving conditions.

Hopefully Mike@Diablo will be able to shed more light on the subject. I have a Diablo chip in my Mark VIII (which was tuned by Lincoln Motorsport), and I am very satisfied with it. I noticed a significant improvement in low-end torque and transmission behavior. If it works as well on GM trucks, I would definitely recommend their products.

i think that 4 sec thing was only for the vortec max 6.0, im not entirely sure tho. i only have the 5.3 and ive never herd of that or felt it (or at least i dont think i have)

I've never felt any delay with my 2001 5.3L either.

From what I've read, the trucks get/show even MORE gains than the cars do.

DO NOT!!! I REPEAT DO NOT BUY A DIABLO TUNER!! IT WILL NOT ALLOW YOU TO REMOVE THE 160kph governor.

BUT YOU CAN GET AN UPDATED/CUSTOM TUNE FROM MIKE/JOHAN THAT WILL!!

TCI makes the necessary components to correct the inherent weakness of the 4L60E. I haven't had any problems with my 4L60E but its nice to know there is a fix if I do.

thats not a big deal, i dont plan on going 100+ mph

Looks like you have a Nelson Tune, and a Hypertech something.

Would you care to comment or explain about it?



btw, I agree on your assessment of TM !

Did you attempt to contact us regarding this issue? How long ago was this, as we never leave an issue like that on the table for very long. If there is a problem where a tool does not do what we say it will do, we make a new revision to fix it, simple enough. Either way, if you give us a call, we will gladly fix this issue for you or provide a custom tune to address it.

What did this have to do with torque management anyway?

Thanks
Mike

TM is basically GM's way of putting an end to the fun before it gets started. There are several different scenarios that bring TM into play. Among these are 'abusive launches' and WOT upshifts/downshifts. When TM is enabled, the PCM thinks you are being abusive, and either pulls timing or closes the throttle body on ETC trucks to kill power. You may drive forever without ever realizing what TM is or does, until you experience a vehicle back-to-back with the TM removed....major difference. Suddenly wheelspin is available at low speeds and WOT upshifts feel much stronger and will produce wheelspin as well. Applying the tunes we make available improve the throttle response in these electronic throttle body vehicles drastically...if you command WOT with your right foot, you get WOT, not what the PCM feels like giving you!

In regards to discussion of a 'delay' in power coming on, some of these GM trucks actually do have a lengthy delay before the PCM will allow you to go into power enrichment mode, meaning you are missing out on alot of acceleration. We recently tested an 07 VortecMax on our dyno, and besides the 25rwhp gains up top, we saw as much as 20rwhp and 25-30(!)ft/lbs of torque between 2500-3500rpm as a result of reducing the PE delay time.

Hope I was able to shed some light on this stuff for you guys...lemme know if you have any other questions.

Thanks

ok, i get all that. but can you damage the tranny by removing the TM? is it there for a reason, or more of a precautionary measure? shifting at WOT, can that damage the tranny at all? i would love to remove it, but im also scared that doing that can cause for my tranny to fail. is this true?

[06MonteSS]

if you totally remove ALL of it, sure it could cause issues down the road... but just removing some of it, and leaving some of it in there, should actually help prolong the tranny, since there will be less slippage.
