Evo 9 ACD ECU Tuning?


Recommended Posts

Hey all this is kind of unrelated to Link or engine tuning, but does anyone on here have any experience with tuning or reflashing the evo 9 ACD ecu? I have a USDM evo 9 and im setting up for some autocross this year. I do all of my own tuning but i have never touched the acd unit. I have done plenty of reading on it and have some maps from other people who have done this but i just wantedto check here and see if anyone has any useful info or maps they would like to share. Thanks!!

Hey thanks for the input. This is very interesting,, I wasn’t even thinking of trying to set up any type of ACD control with the G4x. I didn’t think it was possible because the ACD ecu is its own separate unit. Can I ask how you accomplished this and how it compares to working against a well tuned ACD ecu. I’m guessing you added the acd control wires as inputs to the g4x and then created mapping and set up? I’m interested so please share more if you are willing. And thanks again!

I have done the stock ACD ECU and worked out a stragey on G4X to control Center differentials with 3 different maps for acceleration, and 3 maps for braking. Additionally, there is a slip and steering angle overlay. 
Works quite good! 

Interesting....waiting a explanation..please.
