With 2 ignition outputs provided by the wasted spark driver you could use COP but they would only work when used in wasted spark configuration i.e. coils 1 + 4 would fire at the same time, as would 2 + 3. You would use a 4 channel ignition module like the Bosch 0227 100 211 and wire it up like this:
However I couldn't confirm 100% if that module will work with a weber ecu, as when i tried the 2 channel version with my old wasted spark setup on my old L8 with wasted spark driver it didn't work, same setup on my Autronic SM4 and it worked startight away!
