Anyone know if there is an ECU diagnostic mode achievable thru EVOscan or Similar to get a steady Ignition Siganal ??

can you give more into what your looking for ?

Yes John /yes
I want to make sure that the numeric output of the timing that i am data logging, is the same as the actual timing taken from a timing light. If there is any variance then i can compensate by off setting it.

ok then yes evoscan does allow you to read the current timing in numeric value

Thats not what i want John..
I can read the Numeric Values thru EVOscan and thru my EMU... But i want to double check the numeric values with actual values from a timing light.. To do that accurately i need a steady ignition signal..
Is there anyway of doing this thru maybe a Mitzy diag feature ?
Didn't know whether EVOscan maybe able to trigger this or maybe another program ?

Your best bet is probably to monitor the crank signal, Wodj, but your timing light will need a VERY sensitive input.
Failing that, you could monitor the IFS, I would imagine, but I've never tried that. And, of course, the trigger will be ECU modulated, whereas the crank signal is a mechanical clock.
Any timing light with leading-edge trigger should do it.
