I saw your other post in the MDM is useless thread. I wanted to let you know that I also feel MDM is useless and also let you know that because you were running a square setup that did not maintain the difference in overall diameter between the front and rear wheels the MDM/DSC would work differently than if you were on the stock tires. This means that the wheel speed between the fronts and rears is going to be closer than the computer expects. This could be the reason you felt the MDM wasn't intrusive and worked great.
