Ecu remap/haldex controller
« on: September 09, 2024, 07:23:33 pm »
 :thinking: A remap is always in the back of my mind screaming at me to happen, I was wondering if that would integrate haldex into the map or if it’s a simple get the blue chip so I can add more tq/power to the back wheels, I would presume they are connected in some way, gen 2 same as r32 4motion but bkd engine id say it’s just a a3 Quattro with a golf shell but of course correct me if wrong as I have been using Audi forums to give me more info on haldex.

Haldex is a seperate system to the engine ECU, Haldex software is in the controller on the rear diff which can be changed.

I had the Haldex 'blue' controller on my R32 and it made very little difference tbh.  That was Gen 1 though which was the worst of all the Haldex revisions  :grin:
