VH45 ignitors
VH45 ignitors
The VH45, and im sure the others, such as sr20 and vg30dett, have 1 wire for each COP going in and out of the ignitors. Does anyone know what the ECU sends to signal the ignitor? It should be either a 5v or 12v signal. It could possibly switch ground.

Remember the plug fires when the primary voltage is turned off after being charged [via dwell].

If it's of any use, I found when I had the oscilloscope on mine a while back that the coil saturation time is ~2.6ms @ 14v

yes, that is helpful, thanks for the good info.
