Yea its a great device, I havent really tweaked it yet.Everytime I try to turn off MDS,rear o2,and change the axle ratio to 3.06 the car doesnt like it at all(acts like it has a stall conv. and wont turn over 60 mph at a high rpm ). Now I can just do MDS and it drives fine,without changing any of the other 2 parameters. Anyone else have that problem?????

 

I've turned off MDS and rear O2s at the same time without issues. I'll have to add the axle ratio 3.06 and see if that confuses the setup.

 

Yea!!!!! I got a reply from mike at DIABLO,dont do it unless you have swapped out gears he says that is the problem !!!!!!!
