Default No spark when cranking with CBR coils, it sparks in test mode

So ive got some CBR coils wired up and now cant get it to start.

I tested all spark plugs in test mode and they all work. But when cranking it doesn't do anything

Im using MS3x (i think 3.57) and CBR coils with and Bosch 211 igniter

Spark A - cil1
Spark B - cil3
Spark C - cil4
Spark D - cil2

Ignition output - Falling edge
Spark output - Going high
Number of coils - Coil on plug
Spark hardware in use - MS3X spark
Cam input(if used) - MS3x Cam in



Ive added my tune and my datalog when cranking.

Got it,

This site said it needed to on falling edge

Bosch 0 227 100 211 Ignition Control with MegaSquirt-II

but it i didnt change the CAS so it would still be rising edge.

CBR coils are designed to be fired with a CDI.

What would be the disadvantage in using the Bosch 211, they are working now.
