UNITED MOTORSPORT Performance Haldex software will turn your STOCK Haldex controller in to a performance controller with a simple flash. NO need to change ANY hardware; and is port flashable at our dealers.

UNITED MOTORSPORT Generation 1 Haldex software has hundreds of hours of calibration work and custom strategical control. This software is flashed directly into the Haldex control unit, not into the engines ECU; it will work with all engine ECU software and is not transmission specific. The same torque will be transferred no matter which transmission is fitted. Unlike other available controllers It will also work on diesel models. It does not require any external devices to switch mode; this is all taken care of inside the software.**

Possible modes:

  • PERFORMANCE MODE: When requesting the most performance from your car, our software passes more torque to the rear than ANY other controller. While still retaining drive-ability and keeping with in hardware limits.

    By requesting most performance from your car, we mean by throttle pedal position, so requesting the most performance is foot on floor. The transfer to the rear is proportional to throttle pedal position, ie more the pedal is pressed = more torque is transferred to the rear.
  • ECO MODE: While cruising our software decouples any drive to the rear, this creates better fuel economy while cruising.This decreases wear on an expensive non serviceable part.

    To define cruising: Your car moving along the road at steady speed, the same for throttle position. So if you are driving don the road at a steady 70mph for example; this is when ECO mode will engage.
  • VARIABLE BRAKE DISTRIBUTION: While braking the software applies appropriate torque to the rear. This makes the car more stable in a hard braking situation. A MAJOR part of this control is vehicle speed, which prevents any binding of the drive train whilst steering at ANY low speeds(ie trying to park the car.) This is also true of left foot braking, unlike stock.

    This mode is triggered by the driver braking, ie pressing the brake pedal.

**Just to be clear, if there is ANY detection of front wheel spin during ANY mode the controller will still engage 4wd; just with more available torque transfer. This is illustrated in the chart below

This chart shows how much torque each version of the Gen1 controller is transferring to the rear wheels; it is torque vs gear.



In first gear the peaks on the UM trace are created by wheel spin and our software increasing torque transfer. The dip is recovery from wheel spin. Also on entry into 2nd gear, as the clutch grabbed, this caused wheel spin; and our software reacted to it.

From this chart it is also possible to see that other controllers hit a total maximum torque transfer, and as such are unable to react to wheel spin.


[HR][/HR]
If a controller goes bad that contains our software. Take that and a replacement controller to your local UM dealer. They will verify that the bad controller contains our software. If it does, they will flash your replacement controller with our software.
There is NO charge from UNITED MOTORSPORT, the dealer may charge labour time.

Thanks to Jesse for shooting this video.

That's a BIG statement right there!!! So what is the torque split (F\R) %? Also in "Performance" Mode does the rear clutch disengage when the brake is applied?

So, are you saying that you must be at the event to obtain this discount or are you saying that during this event the discount is available at the event and at your dealers while the event is under way? No way could I justify flying out to the event with the controller in hand from Arizona to save $100.

The Competition Haldex puts out a split of 55% Front\45% Rear plus the rear never disengages under braking....... This is the Platinum Standard to beat!!!

Very nice guys, took a little longer than I was told but it's worth the wait. It's a game changer.

I'm curious to know. How much more stress will this be putting on the stepping motor?
