wow dont post 4 in the morning , bad english

I just thought i'd clear it up abit

The maximizer is controlled by a laptop , the softwere that is used for tuning has a builtin rpm meter , according to the install manual the wire used to read the rpm should be connected to one of the coils.

I did a search here on ceg and found out that others had some problems setting up a tachometer.

my problem is that I get very bumpy readings but I guess thats how the actuall rpm looks like when you meassure it in numbers instead of a regular analouge gauge.

I also searched for the maximizer but it looks like none has been using it.

Is there a problem with taking rpm signal from the coils on a Contour SVT?
