What the signal across the coil looks like from a BIM024 module at idle (800rpm)
Posted by leigh on February 11th, 2008Check this out, i put my bitscope on the +ve and earth of the coil to see the ignition pulses, if you click on the image you can see the voltage rising to 13.4v (VP) and you can see the time where there is no current (where it has just discharged) at 24ms (TM) i think the spike around there is the coil itself letting go thru the high-tension line sending out some EMI
This is from my '79 chrysler valiant CM GLX at around 800rpm, it's a 265ci 6 cylinder
