Coil Near Plug conversion Timing light will not work with LS coils

As the title of the post states, my timing light will not work with LS coils.

I am in the process of finishing up my Coil Near Plug conversion on my Big Block Dart GT convertible "Home-Brewed"

This is an XFI 2.0 and XIM system.

The car starts and runs.

I am trying to check my base timing by setting the fixed timing to 20*, but the timing light will not flash.

I have a Actron CP7528 inductive timing light.

This timing light works on my 5.7 Hemi in my 2003 Ram and everything else I use it on.

Any ideas or help would be appreciated.

Thanks,

Herb aka "Dart67"
