Instead of winding one piece of wire around the core for n turns you wind two wires around the core for n turns. Keep it nice and neat and it looks like one long piece of wire but has two connections at one end of the winding and two at the other end of the winding. This makes for more efficient coupling than once winding put on top of the second winding.

For a sec and a pri, they are laid next to each other, not one on top of the other (and this has nothing to do with the fairer [oh, never mind]. . .) BobR. Trifilar and quadfilar mean just that, three or four windings done together. > Date: Sun, 21 Nov 1999 08:38:00 -0800 > From: rhuish@xxx.com > Subject: Re: DIS > > - - ----- Original Message ----- > From: scott christensen > Subject: DIS > > >>MSD is adverising a DIS 4 cylinder unit in the foreign car mags > >>(Sport Compact Car), ie sold in USA about foreign. > > >Might hook up with one of the guys from AU., there is a CD kit > >available. > >Down side is winding your own transformer. > >Grumpy > > I bought one of those CD kits.(JayCar, AU)...looks good, has all > the components and documentation.

Not to mention how frustrating it is to wade through each e-mail with "Re: DIY_EFI Digest #???" in it. I'm never sure if it's something I care to read or not. If this were to become a newsgroup, it would make it easier to wade through what you don't care to read and what you do care to read, not to mention the threading abilities and the larger reader base you'd get. (I'd also be more willing to participate more as I'm sure others would.) Although, I do admit it makes it easier for spammers to get your address; isn't it pretty easy for them to get it in the first place? (Even without being in a newsgroup?) BTW, my current project right now is heavily modifying my 1982 Corvette. I realize this is an arduous task considering the nature of the Cross-Fire Injection system, but I have done my research (some of it from here, others from books and individuals) on tricks to improve it. I have other projects in the kettle that aren't necessarily specific to the Cross-Fire as well that are helpful for anyone embarking on DIY-EFI projects. My home page can be found at home.houston.rr.com/ken73 - please be aware that this link will re-direct you to my home server at my house. (I have a dynamic IP on a cable modem that is linked to that home page.) May I suggest that anyone without a newsreader please respond, and maybe we can go towards that direction (Newsgroup?) if no one objects?

Specs? This looks real interesting, two of these and the XR700's, and I'm there. Can anyone identify it?
