I've been told that when i go to wolf 3d v4 i will need new trailing modules wired up because the factory ecu has a different way of firing and there's problems with reliablity.

I want to keep my factory coils (so cops don't know i have aftermarket ecu) but want everything to work properly with good spark. What should i do?

What do i need to get hall effect trigger working?

thanks

 

You are right the V4 wolf will not run stock S4 coil trailing pack the reason is that one of the signals to the trailing coil selects coil 1 or 2 (T Select) their is also a firing signal that fires the selected coil. The Standard V4 setup fires the 4 lgnition leads as required for each coil on the falling edge of the signal from trhe Wolf. Now it should be possible to make a electronic circuit to mimic the T Select signal. The other option is to use standard trailing coils and make a custom ignitor.
