Might hook up with one of the guys from AU., there is a CD kit available. Down side is winding your own transformer. Grumpy | 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 | | ______________________________________________________ | Get Your Private, Free Email at http://www.hotmail.com | ------------------------------ End of DIY_EFI Digest V4 #653 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
