Hondata Traction Control

Traction Control for your s300, KPro or FlashPro. Hondata Traction Control works by monitoring the ABS wheel speed sensors and reducing engine output when excessive wheel-spin is detected.  A dash mountable switch allows the selection of different target slip rates, and software allows the system to be tuned for your specific vehicle setup.

Compatibility

• Fully programmable module with wheel speed sensor inputs and adjustable output to ECU.
• Works with inductive, active and hall effect sensors.
• One button to set wheel speed sensor calibration.
• Drive axle setup.
• On the fly adjustable target wheel slip.
• Live data monitoring.
• Twenty seconds of high resolution on board datalogging memory for setup and diagnostics.
• Wheel speed sensor error logging.
• Settings for target slip while cornering.
• PID control of output.
• Owner registration and password protection for security.
• Serial and CAN outputs for future expansion.

How does it work?
Simply put, the Traction Control commands the ECU to reduce power when the driven wheels are going faster than the un-driven wheels.  On-the-fly adjustment of the target slip rate can be performed using a dash mounted switch.

Will this work on my vehicle?
If you have ABS, then the ABS sensors can be utilized.  If your vehicle does not have ABS but is a model which supports ABS, then only the wheel speed sensors need to be installed.  If you don't have ABS and no factory vehicle wheel speed sensors, then you will need to add your own ABS wheel speed sensors.

Is this only for race cars?
No, it works very well on street cars.

Is this better than using a vehicle speed sensor for driveshaft rotation speed?
Yes. The ABS ring typically gives 50 pulses per wheel revolution. The vehicle speed sensor on an 02 Acura RSX for example gives around 4 pulses per wheel revolution, which reduces the accuracy of your speed determination. In addition, the VSS cannot be used to determine if the car is cornering.

Can you change tire sizes?
Yes, setting up for different sized tires is very easy.

Will this work on both front and rear wheel drive vehicles?
Yes, the principle behind the wheel slip calculation is exactly the same for front and rear wheel drive.

Does the Traction Control affect the ABS operation?
The Traction Control module has high impedance capacitively coupled wheel speed inputs which do not alter the signal to the ABS computer. However, if the ABS error light illuminates, or the ABS operation changes in any way, the vehicle should not be driven until the issue is identified and fixed.

Do I need an ABS computer, or just the wheel speed sensors?
Only the wheel speed sensors.

Do I need four wheel speed sensors?
Traction control will work with just one front and one rear speed sensor, but cornering slip compensation cannot be calculated unless you have two sensors on the un-driven wheels.

Will hall effect sensors work?
Yes, tie the negative side of the wheel speed sensor input to ground.

My car lifts one rear (FWD) / front (RWD) wheel off the ground when cornering. Will the traction control cope with this?
Yes, just set the speed determination method of that axle to 'fastest wheel'.
