I wrote to Nik at HPA today. Is asked him to explain the difference between the Blue Haldex controller and theirs. (Theirs was an Orange Haldex Controller and now it’s silver; no paint at all).
So here’s Nik answer:
“In the past we had sold both the blue controller as well as our competition controller. We elected to stop selling the blue controller as many of our customers ended up exchanging the blue controller for the competition controller. I haven’t even had one inquiry for the blue controller in the past two years!
The main difference between them is that the competition controller will not stop transferring torque to the rear wheels when you lift off the throttle.
It will enable you to achieve slight oversteer should you desire and it will not have to “re-load” torque to the rear when you depress the accelerator pedal again.
I have driven cars equipped with the OE, blue sport, and competition controllers. I don’t believe there is enough value in the blue controller for the money when you consider the minimal difference between it and the OE controller.
Having had experience with all three units, if I were to spend nearly $1000 on a replacement, I would have to go straight to the competition controller.”
I will be buying HPA’s controller soon. I am also planning on creating a video of my car spinning before and after the controller change. Hopefully, we should see only the front wheels engaged before and the rear and front engaged with the new controller. Keep watching!
