First off, I was surprised that nearly no one checks the ignition timing in the EMS vs the crank position. With a good tune the base timing map would accomodate for a differential in the the anticipated and actual but there are portions of the tune where accuracty would yeild a better tune.On my last setup I was able to adjust the timing easily as I was not using the factory ignition. I have since removed the system so that I could do some testing on the factory system again.

Anyway, the only way I have figured our to test the timing is to pull the #1 coil and plug in a spark intensity tester then use my inductive loop from my timing light around the lead for the tester.

I have tried to use the coil signal wire but my light cannot pick up the signal. When I use the coil power wire I get a signal that is app 15 deg off of what I believe to be the correct position.

If anyone has a better way of testing I would be interested in hearing.

 

Well that was the road I was going down, but as you mentioned my method was only acceptable in a static position during idle. With my other ignition system I did both and had to adjust the sync position but there was no drift.

Thanks for the heads up

 

So w/o a jumper wire their is no way to test the dynamic timing?

 

You can pick up one of Evans high output ignition systems which gives you a place to clamp

 

[QUOTE=Evans Tuning,Sep 8 2010, 12:16 PM] I have a ton of MSD wires that are made up with different plug/coil ends on them to act as a jumper wire between the coil and plug.

 

^ Yup just grab a spark plug wire small enough to fit onto the spark plug and then pull the rubber boot off the other end and stick it into the coil pack. The coil pack just sits on top of the valve cover with the wire firing the plug. Put your pickup on the wire between the spark plug and the coil pack.

 

^^Sounds good and thanks.

 

Raised from the dead, but does anyone have a recommendation of a spark wire set that will fit?

 

just buy a timing light from auto parts store, clamp it to cylinder 1 coil pack wire

 

I have the timing light, but apparently there is not a lot of room to get a good reading from coil 1.
