Hi Guys,

I have tried alot of stuff fiddling around with it but it just doesnt seem to make a difference can any body tell me a step by step way to completely turn off torque management in the engine as well as transmission? My Vette 2010 LS3 with Auto trans "6L80"




Am I need to change anything else in Transmission TM or not?

Thanks in advance.

I turned it off with my Intune in the TCM programming. Selected 'firm,' then another screen in the "modify" section allowed me to turn it off completely. Really made my '13 A-6 come alive. Any tuner should be able to do it, but the Intune makes it a piece of cake.

In HPT there are switches in the transmission section to turn off TM. It is best you understand exactly what you are turning off before you do it. There is plenty of reading on the topic on HP Tuners forums.

Thank you guys, i tried many things but the transmission isn't working fine after those changes and i returned the old file.

I will try to search to find something.

Hello I have EFILIVE so you'll have to interpret which of HP's tables are the same ones---

The TQ management in a LS3 is called TQ CONTOL and they seem to be the same tables for Traction Control (TCS) and TQ control
To disable the Traction control ( so the tires can spin)

Go to the Eng file
open TQ Control
Click on "parameters"
Set the TCS Minimum TQ to 480
Set theTCS Minimum coolant temp to 400

This will delete the Traction Control
Now delrting the TQ Control (or management is tricky on an automatic car--Because the ECM uses these tables to remove TQ during upshifts and downshifts at full throttle
IF you delete all of the control it will bang the gears so hard you'll feel like your trans is going to fly into the cabin---Super hard on the trans and you can easily break it
However there are a few tables that you can alter to "Soften the TQ control ---so you don't lose so much momemtum at each shift

Again in the ENG file in TQ Control
TQ reduction spark--fuel and throttle ---set to NO
Wheel Hop TQ Reduction spark --fuel and throttle ---set to NO
Axle TQ Protection ---spark--fuel and throttle ---set to NO
Clunk Reduction --- spark only to NO
TCS Throttle limiter by gear---set entire table to max---6046
TCS Throttle limiter by input speed DOUBLE the entire table

And finally this table gets rid of unwanted spark deducts on a hard launch which feels like a sort of traction control by removing up to 10*
of timing and making the car lazy
In the SPARK table--go to the KNOCK tables
Find KNOCK FAST ATTACK RETARD LIMIT
AT WOT the stock value is 10* at WOT
start at 2000 RPM all the way to the end 8000 RPM
Then at WOT OR from 13.1 to 14.6 MAP in PSI enter "0" in all those boxes

I tune all the LS3's this way and have had excellent results--Just be careful remember no more traction control

Hi tblu92, thank you for reply i will work on it today and i will back to you with my feedback

I applaud you for trying to accomplish this on your own as I too like to tune my own vehicles when its not over my head. however, this platform with all the electronic tuning needed for the tranny and engine to play nice together is. I would hate to read a post from you where your tranny stops shifting correctly. imo...the few hundred $$ saved from not having a knowledgeable tuner tune it isn't worth the cost of repairing/replacing the tranny.
good luck!

Hello tennblkc6, thank you for your points. Just for your information i tried that by my self because I love to discover those things not about the money. I already know everything about Gen 3 and I bought the Hptuners and two widebands that's mean I need to know how I can do that with correct way.

Thank you again for your notes.

Engine tm is easy and "safer" to mess with - just go to the tables for torque vs gear and max them out. you can also disable the tm dropdowns.

Trans tm can be disabled by just shutting everything off on its dropdowns. You posted the engine tm table, but Im not sure if youve seen the trans one... its got its own other set of bs to take care of


If you want your trans to shift sooner, just lower the shift time tables and up the pressures.... You can also look at the inertia tables as well. I believe there is a file for a 2010 GS Automatic tune on the HP tuners repository from a forum member that races vettes... you could compare that for some ideas on where to start.


Beyond that keep in mind if you disable downshift tm, it will get rid of rev matching. This sucks because although you could just rev match the gearchanges yourself, in manual mode, youd be sol in automatic.

Luckily, I have found a work around for the lazy downshifts in manual mode:

When you downshift in manual mode, slightly blip the throttle and it will make the car shift faster - for two reasons the commanded shift time is going to be faster and the torque management isnt going to be lazy in its rev matching. The factory makes the rev match very lazy and unfortunately you cant tune it in hptuners, so getting on the throttle a bit makes the torque go up and all the car has to do is remove some of that torque (if you overdo it) to get to the desired rate. It takes some practice to get it right, but it makes the car a lot more fun to drive.

be careful about removing transmission torque management - it does serve a purpose, and while built A6 transmissions can handle no tm, there are many reports of stock ones wearing out quick without it.

good luck!

Not always true----TQ management by design is there to soften the shifts--- In an LS3 this is accomplished partially by slipping the trans clutches- Which wears out and overheats the trans far worse than quick crisp shifts---Deleting TM does however not protect the trans from a driver with no common sense---It takes the control away from the computer and places it on the shoulders of the DRIVER !!

I have an intune and trying to do this also..possible could you step me through the process...thanks

While I don't have "Intune" but instead have "EFI Live", I am trying to do the same end result, can anybody tell me how to eliminate the Torque Management on my 2011 Grand Sport using EFI Live??
