What is MQB?

MQB refers to a platform shared amoung many of the Volkswagen Auto Group (VAG) companies.

Modularer Querbaukasten (Modular Transverse Matrix)
The Transverse mounted front-wheel-drive or All-wheel-drive platform upon which multiple cars have been driven. Among which COBB Offers support for:

MK7 GTI
MK7 Golf R
MK7.5 GTI
A7 Jetta GLI
Audi 8V S3
Audi 8V A3

How To Enable:

This feature is enabled on all OTS Maps. It is enabled at the same time as the factory traction control. It will typically perform better if you only use the COBB traction control as the cut is less agressive. To use this instead of factory traction control, be on a slot with it enabled and turn off factory traction control using the button or vehicle menu in your vehicle.

The ECU is not capable of remembering the value set in this adjustment after the car has been turned off or key-cycled. As such it will need to be set back to the desired value manually each time.

How it Works:

The COBB Custom Traction Control works in a manner similar to the factory offering, however it works much better and faster to minimize wheel slip and keep the car planted at all times. At it's simplest the software is looking at the various wheel speed sensors to determine if one is moving more quickly than others. When it detects that one wheel is moving at a higher speed than another, this is typically an indication of the wheel slipping. There are some instances where the wheels will move at different speeds (around corners for instance) but this is something tuned for in the map itself (you shouldn't need to worry about adjusting it to go around a corner properly). As the ECU sees the difference increase and detects a slip, it will reduce the amount of torque the engine is producing, this should slow down the wheel enough to grab on to the pavement again so you can continue accelerating. If it isn't able to regain traction, the ECU will continue to reduce power until it sees traction again. This means that with the traction control on the default setting where it minimizes any wheel spin the car is hypothetically the fastest as no wheel speed is ever lost.

Steps to Adjust:

Adjusting the Traction Slip Target Multiplier allows control of just how much your wheels will slip at any given time.. With the traction control set to 100% it will minimize any wheel spin by reducing torque slightly when wheel slip occurs. Usage of this feature can allow the optimal mixture of slip and traction for the best results. For some people this makes the car seem slower even though it's at the limit of traction. As a result, changing to the next higher slot numerically (which has the effect of allowing slightly more wheel spin) can add a bit more of a sensation of speed. In addition it will allow more tire slip while (Ideally) maintaining usable traction.

From there select Adjustments
Now select Traction Slip Multiplier
(Current Stage1 OTS only)
Slot 1 Has COBB Traction Control disabled
Slot 2 Has COBB Traction Control set to allow 0% Wheel Slip
Each in between value(3-8) is progressive, allowing the wheel to slip more and more as the value increases.
Slot 9 Has COBB Traction Control disabled as well, but can be custom tuned to anything by a protuner.

(Current Stage2 and Stage3 OTS maps)
Slot 1 Has COBB Traction Control set to allow 0% wheel slip
Slot 9 Has COBB Traction Control disabled
Each in between value(2-8) is progressive, allowing the wheel to slip more and more as the value increases.

Things To Look Out For:

WARNING - ALLOWING WHEEL SPIN CAN BE ABUSIVE TO THE ENGINE, CLUTCH, TRANSMISSION, AXLES, TIRES, AND DIFFERENTIAL. THE USER ACCEPTS ALL RISKS AND RESPONSIBILITIES WHEN USING THIS FEATURE
