Cosworth Wasted Spark Conversion for Weber ECU's.

This system gets rid of the antiquated distributor cap and rotor arm system allowing you to replace it with a far more modern twin coil wasted spark system. As well as being solid state with no moving parts to wear out, the best benefit is you will no longer suffer from having to run tiny plug gaps and be subjected to the constant and annoying misfires that the Ford Sierra and Escort Cosworths are so famous for.

MSD Wasted Spark for Weber

Key Points:

  • No more distributor cap and rotor arm
  • Twice the charge time so twice the spark energy available
  • Variable dwell time depending on engine RPM.
  • The ecu requires no software alterations whatsoever for this conversion.


The Cosworth wasted spark coil pack conversion is available for all Cosworth fitment Weber Marelli ECU versions such as L1. L1A, L6, L600, L8 and P8 including Ecu’s converted to Pectel Super 8.

The distributor cap, rotor arm, coil HT lead and standard coil are removed from the car totally leaving you with a solid state non moving HT ignition system with less HT connections and only 1 gap for the voltage to jump, the all important spark plug gap.
