EDIS Spark Advance Testing
Hi,
Im currently runing MS1 V2.2 with the latest MS'n'Extra code.
Its modded for EDIS and all up and running on my Zetec.
However, I am not entirely convinced the Spark is advancing.
What is the best way to test? I have tried increasing/decreasing the spark table at idle but I dont see any changes in engine speed.
Any tips?

you shold be able to easily notice it with a use of timing light at idle.
again, at idle try retarding the spark... 10-15 deg should cause noticable difference in how the engine is running. if not, retard it more. if you retarded it 30 deg and still no difference then definitely, your EIDS is running in 10 deg 'limp' mode and you have no control over timing.

surly there is a mark somewhere at 1st cyl TDC. if it's not on crank pulley then make one. all you ned to do is to confirm that it moves backwards and forward as you advance/retard timing.

I managed to get mine working last week.
There were a couple of issues. Firstly the resisitor in place of D8 was the incorrect value.
Secondly the setting in the "Spark Settings" was incorrect for the trigger angle. I had to set it to "60".
I would check your settings. Read through the megamanual as the settings are documented there.

Trigger Angle = 0 is correct for MS1/ExtraAsad wrote: Secondly the setting in the "Spark Settings" was incorrect for the trigger angle. I had to set it to "0".
MS2 users must consult the MS2 docs.
Even if your engine doesn't have any obvious timing marks you can make rudimentary checks - stop the engine and draw a chalk line on the crank pulley. Run the engine and use a strobe see where that line is. Adjust the timing using "Fixed Angle" on spark settings. It MUST change as you do this and you should here the engine tone alter. Otherwise you most likely have a SAW output problem.
Top three problems are:
incorrect "Spark A" setting in Megatune
incorrect inverted/non-inverted output
missed out some of board mods
wiring error
