MSD is adverising a DIS 4 cylinder unit in the foreign car mags (Sport
Commpact Car), ie sold in USA about forgeign.
Might hook up with one of the guys from AU., there is a CD kit available.
Down side is winding your own transformer.

| Hi everyone.  Just joined.
|
| I am doing research to roll-my-own DIS for a 4 cylinder aircraft engine.
I
| would like to control the timing advance with a microcontroller based
mainly
| on the MAP reading.  (in aircraft RPM's stay constant but MAP changes
| drastically with altitude variation)
|
| A few questions for the group:
|
| 1) I like this CDI multi-fire MSD-6A unit (~$130).  Is there a similar
|    unit that can control two different coils simultaneously for a four
|    cylinder engine, ala "waste-fire" style?
|
| 2) I found this waste-fire coil picture here on efi332:
|      ftp://efi332.eng.ohio-state.edu/incoming/coil.jpg
|    Anybody know what this coil is from?  Specs?
|
| 3) Anybody out there roll-their-own CDI coil driver circuitry?  (or
|    use the "capacitive discharge driver" circuit from Zublin's
|    MSD-6A article)
|
| Thanks
|
| Scott
