Hey Andre,

I have a few doubts in this module.

A. Do we use the numbers displayed on the timing light's lcd onto the laptop? Yours was showing 2 wierdly.

B. When the light flashes ( as i point it at the pulley) and i have a degree marked balancer , does that mean it will flash exactly at the same time as the mark of a specific number appears pointing upwards?{i am also assuming ignition happens at atleast one of the cylinders at this point} ( this question i asked because a friend of mine was saying something about it and i got confused, entirely).

C. On EFI cars does it really retard or advance my ignition timing if i fiddle with the up or down button on my timing light?
