Testing coils on a coil over plug system?

[buzzinhalfdozen]

Art, the sensor should work correctly using any voltage within it's operating range, in this case more is not realy a good thing. You can test this sensor very easily... take your volt meter hook into the sensor signal wire( the one sending voltage back to the ECU) hook other meter lead to ground. Power up system so sensor has power, next pass a metal object by the sensor, you should see the signal voltage "toggle" switch from 8 volts to 0 volts. I've found it's best to check this at the ECU to verify the signal is getting to the ECU. If you see no voltage switch at the ECU, next try the same test at the sensor connector, if you now see switching then you have a simple wiring issue between the 2 devices. Please try this test and let us know the results. By the way I also noticed that you need to set the "trigger pull up resistors" in your trigger1 and trigger2 sub menus, this is set correctly?Another consideration is the polarity of your crank sensor, being a VR type sensor you really need it wired correctly, I know from experience that they will work even if polarity is reversed however not correctly. To figure out the polarity requires the use of a "scope" unless of course the sensor supplier supplied this info to you.
