hi, do i need some fancy timing light to check my edis ignition timing? I have some doubts to wether the timing is being altered by Megasquirt, anyone help pls?

any one will do,remember it has wasted spark tho and if a rev counter is fitted it will show 2X revs unless you set it to 8 cylinders

If you've got the sort of timing light that clips over the plug lead (inductive type) then you may find that you get a rubbish or unreliable flash when clipped onto plug lead 1 - the easy answer is to either clip onto lead 4, or to turn the clip over.

I thought my Megajolt / EDIS was knackered until I worked that one out...

I used a gunson from halford timing light.
Worked perfectly on an edis 6 setup.
Because of wasted spark remember that you will get 2 flashes, so once per rpm (might limit top rpm capabilities).

im sorry but your wrong there, connected mine up to pin 2 i think and my rev counter reads the right revs. just connected the wire labelled electronic input on the rev counter

mine reads from the ht lead,no need to attach to any other wires

just plug your laptop in and run the car with the software open and you will be able to see the ignition map change on screen if it is working correctly
