Help: Anyone Know How Many Ignition Pulses Per Crank/Camshaft Rotation?

[rreinicherr]

I am trying tio set my RPM converter on my Innovate LM-1. I need to know how many ignition pilses per crank rotation or camshaft rotation. I am picking up the signal from the Dark Blue and Whiter wire in lower PCM harness.

It is not reading the RPMs correctly.

THANKS!

Yes, Cylinder #1 w/ wastespark. Its a pain in the rear too

I just read on the Viper Club site that the engine fires every 54 degrees and 90 degrees. Therefore all 10 cylinders fire in two crank rotations. I am going to try 2.5 impulses per one crank rotation. It shows 5 cylinders on the screen. I am going to go out in the driveway and try it now.

That seems to be pretty close. The graph sure looks alot better.

I will try a regular run tomorrow.

THANKS!
