Updates,

Finally got the car back on the road and the first snow melted away. All the wirings was correctly wired and the problem was the IDC didn?t exceed 44%. I turned the threshold from clock 12 to clock 9 and the system started spraying. I?m seeing 2-3 bars in the gauge so it still needs some adjustment. My tune is at the early stage but I wouldn?t have thought that IDC was under 44% since I?running ~24psi with 72lbs. Also the injector (+) confused a lot because it didn?t have the 12V as most car do so for future reference to other S4 2.7 owner this is how these cars differs from others.

Thanks to Richard and Howerton Engineering for great customer support.
