That device did not work on my 12 and have heard similar reports from others a while ago but nothing lately. Maybe the newest firmware fixed it. I sold mine to a guy with a turbo'd 08 and it worked for him.
Neat little box, great idea if it functions as advertised.
are you sure that you connected everything right? its pretty much impossible for it not to work. its actually universal and could work on any car with coil ignition.
