Message	is guilty : I tried on another Z and found 30 degrees. Maybe this is because I have a timing gun which is designed to work with a very high voltage wire and not with a PTU or coil pack wire. BUT : 1) I had 35 degrees of advance on the PTU loop, and 30 degrees on the coil pack... 5 degrees difference, why ? And on the coil pack, I had to put my timing gun connector around the wire in the middle : it didn't work with the 3 wires all together. 2) With a warm engine and at idle (700 RPM), the Conzult told me the ECU was at 15 degrees, but the Zemulator (in real time mode) told me the ECU was switching to one of 3 cells (RPM, TP) : (400, 8)=15deg, (400, 16)=25deg, (800, 8)=15deg. I'm wondering why at idle (with no load, low RPM) TP is (sometimes) at 16... Any comment ?
