I had an issues with my cop setup where one of my coil drivers burned out in my AEM part way through a tuning session.
Here is how I did everything

Just wondering if anyone can see any issues with how this is done that could have caused this issue. The plug between the coils and the ecu have since been eliminated and the wires all sodered/heat shrinked together just incase there could have been an issue there. Should I have a bigger ground or + wire maybe?

The other issue is the stock tach is only showing half the rpms, in the AEM itself it is show full rpms. Anyone have any idea why this could be happening?

 

Ok so lets pretend the only issue is the tach reading half.
Anyone have any ideas why the tach isn't reading properly or what can be done to fix it?
I'm assuming it has something to do with the t1 cam trigger being a 12:1 tooth and the stock dizzy being a 24:1. Is there any way to convert this signal. Or am I just way off base with thinking that is the problem?
