It all started when I tried to install a rev counter in my Panda (clasic). I found very useful inforation in the forum and it was prety shure that if I take the singal that is needed for the rev counter from pin 23 on the ECU everything was gonna be ok. But pin 23 in my case didn't give me the signal. I tried to connect the rev counter as it was described in the installation instructions by the manufacturer but I had only the half reading beause the engine is equiped with 2 coils so 1 coil per 2 cyliders is half the revs on a 4 cilider measuring tachometer.
