HELP!,Bosch 0221506002 coils.
 

My C230 turbo setup runs 0221506002 ignition coils(new replacment oe items)

We run a Motec ECU and use a bosch ignition modual to switch the coils,however we are getting this wierd misfire which can accure high in the rpm with to much dwell(dropping it to 1.4ms at higher RPM sort of fixs it,however it makes the low end of the RPM miss so it needs to be up around 3ms for a smooth idle...its all a bit wierd)

We have tried swapping polarity to the coils etc etc but it made no real difference.

My question is...do the 0221506002 coils have more inside them then just a pair of windings?...is there extra internal circuitry for supression or switching?

Any help would be appreciated.

Cheers,
Paul
