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.

"When I say that the Hondata Traction Control system is awesome, I do not say
I have a high HP turbocharged 2008 Honda Civic Si running FlashPro with a built
motor and PPG geared transmission with a 64mm Comp Turbo turbocharger. When we
initially broke it in on 91 octane it made 560whp at 13psi of boost pressure,
and has since been retuned on E85 running as much a 26psi making somewhere in
the realm of 700-750whp.
Now this is mainly a street car with occasional quarter mile track visits – a
full interior OEM looking vehicle with nothing that makes it stand out as
anything but a typical Honda Civic other than the open wastegate dump and
exploding tire smoke when I go full throttle. To say getting the car
“manageable” for street driving was an understatement. In attempts to get it
manageable I put a 3psi WG spring in and dialed the car in using the Hondata
Boost Control system that comes with the FlashPro engine management software to
limit boost in early gears for traction.
This got me very close to a manageable high HP front wheel drive street car –
but it was still wanting. Boost settings that work great when it’s 80 degrees
out and the sticky summer tires are warm don’t necessarily work in cooler
temperatures, or worse – rough road. Still not quite what I wanted – which was a
fast and fun street car. Sure I got close with boost by gear – but it was still
a handful to control the car.
Enter the Hondata Traction Control system – this is exactly what was missing. A
robust system with an intuitive interface to manage wheel spin using the OEM
wheel speed sensors that come on the vehicle. Installation was simple and clean.
One weekend dialing in the settings for the new system and it filled in all the
gaps that boost by gear could never fill in on its own. The car was now an
absolute blast to drive – no more “hang on and hope it doesn’t kill you”, but
more so “hang on and enjoy the ride”. I could turn out and floor it in 1st gear
and the car just GOES. As boost increases and power increases to the traction
limit managed by the Hondata Traction Control unit the car just goes faster and
faster with every gear shift.
It’s simply amazing.
I’ve had multiple passengers that have ridden along with me, and their
statements always bring a grin to my face: “OMG OMG!” “WOW!” “What?? I just
expected wheel spin with this much power!”
I liked the product so much I installed a second unit in my turbo 400hp Acura

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
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
Yes, just set the speed determination method of that axle to 'fastest wheel'.
