I have no TCS intervention. No codes, no comms errors and no indication that it comes on from the DIC or dash lights. I have taken my car to am empty parking lot and induced several spins to check this out. It is like my car doesn't have any TCS or AH installed. TC and AH were on.

I have a 2001 coupe with a Procharger kit. It has a MN6 transmition. It put down 460 RWHP on 7 psi boost on a Mustang dyno.

I have read all the posts here and on the net. A lot of them indicate that a tuner can desensitize TCS by modifying the torque management tables and the TCS tables, but I am not seeing a definitive answer.

I would like some traction control for safety reasons. Is it possible to tune a car and still maintain some TC?

Did your tuner manipulate anything related to sizing of tires to try and calibrate the speedo? This would only be valid if you are running a different OD tire...

01vetter

I have stock tires. I don't know what he adjusted.

Tune runs great, just no TCS that I can detect. No codes, no Comms messages.

95rtturbo

OK, then I doubt he would have manipulated anything related to that.

Yes it can.
I have LS1 edit and getting ready to change over to HP Tuners.
I tuned the TCS out because when I pulled out from a gravel road to pavement, the car would almost shut down due to tire slip. I'd be a sitting duck for a second or two as it wouldn't accelerate.
Yes it still "works" but it does seem like it is ineffective when on. It just isn't near as intrusive. It certainly fits my style of driving.
I notice tuning it almost out did not effect the active handling aspect, just traction control. I do track the car so I know that it.
Mine is the 6SP also with a built LS6 on N2O.

I will add the stock traction control is very effective in the snow. I had a 1/4 mile long driveway in Colorado, uphill, and I could only climb it in the snow with the traction control on. Off, I'd get nowhere.

Can you share what you changed from stock to desensitize TCS? What tables and settings did you change?

RonSSNova

You can tune out the engine settings related to TCS.
But you can't affect the TCS control of the brakes.

I'm not familiar with HP Tuners, but soon will be as I'm switching to it because of the other vehicles I want to tune.



LS1 edit
4.5.1 Torque Management Frame
4.5.1.1 TCS Retard vs. RPM
There are 2 retard tables used by the traction control system, only one seems to be used in each application. The table shows the amount of timing retard for a given RPM.

4.5.1.2 Torque Reduction
This table defines the Timing retard used to implement the torque reduction that is requested in the shift table.. It defines the timing retard that is used for a requested % torque reduction. See the Transmission Page, Shift Firmness tabs for the Abuse control parameters.

4.5.1.3 Abuse Mode Test
This test is in the engine code. The test is only run when the transmission is in gear, and Engine RPM is above this threshold, and the Speed is below this threshold. So if you set the Speed = 0, and the RPM = 7000, The abuse test will only run when you are in gear with the engine RPM > 7000, and the Speed < 0 MPH. Which will disable this test.

4.5.1.4 TRQ by Gear
Maximum engine torque, by gear and RPM. This is to protect the transmission.

4.5.1.5 Tip-In TRQ Limit
Maximum Rate of torque increase per gear

4.5.1.6 Max Eng Trq
Maximum Engine torque as a function of RPM. This is a control in the traction control section.

4.5.2 Maximum Torque
This parameter is a maximum torque limit. It is in Foot Pounds.

4.5.3 Axle Torque Limits
This is the torque limit In Foot Pounds that is used to protect the axles
4.5.4 DriveShaft Torque Limits
This is the torque limit in Foot Pounds used to protect the drive shafts
4.5.5 Axle Abuse Enable
Allows you to disable the Axle protection
4.5.6 ETC control for Axle Abuse
This allows Electronic throttle control for axle protection.
4.5.7 Transmission shaft Protection
This is the Input and output shaft maximum torque limit.

Yes I agree a tuner can with tuning get rid of all of your traction control---
Also remember that traction control and TQ Management are 2 different issues and tables in your tune-----
-TC prevents the wheels from spinning
TQ management limits TQ at various times while your engine is running or shifting
The max limit on your ECM is 640 Ft Lbs of TQ on the TCS ---The stock number is inputted at 350----- But to completely delete TCS there are sevaral trigger points thst have to be changed to completely delete it-----Those are like max RPM---max ECT max IAT as well as wome others----
On a manual trans YES I would want some TCS put back into it for daily driving or driving on a wet road foe safety's sake----You can always turn if OFF when you want to---
I would ask your tuner for an adjustmet or if you bought it already tuned get a re-tune

I've detuned mine but still get notification on the DIC.

RonSSNova

Same. And, if I don't turn TC off at the track, it won't do a burnout.
So it's certainly not fully disabled.
