unsolder the blue ground wire. Solder in a new longer blue wire and a white wire into the other soldering point. run those wires to a the blue and the white of the HPI box and ground the black wire and boom, you've got the full HPI curve.
and just like below, you can use the stock flywheel if you'd like :)

This is it right here for your E50. This coil fits on any Bosch points stator plate, and you can wire it to any 1 wire CDI box. I run mine with a parmakit box, get an awesome curve, all with the stock Bosch flywheel and stator plate. Sure, you gotta time it without a woodruff key, but you don't need them anyways. I suppose this will work for any other Bosch ignition setup too. Too good, too easy!
run it with an HPI CDI box :)
