SVT coil on plug ignition

[athens7]

Eliminates the distributor and plug wires (always trying to clean up a crowded engine bay) , plus picked up a couple of hp and lbs-ft using copper plugs instead of the platinum ones. If anyone knows what the electrical connector that mounts on the distributor bracket is for (upper center of picture, with green wire), please chime in; I'd like to remove the bracket, but don't want to eliminate a necessary ground until I have an alternative.

On the early Foci I have info on (2000 - ) it's for a noise suppression capacitor, so that the electronics in this subsystem don't make their presence known to the radio.

Nice technology, small, light, space saving. What all did you change to make it work?

The connector visible in the foreground of the bottom center of the 2nd photo was spliced into the harness. I chose to keep the original connector to the distributor in place so that I could use either system (as much for testing as anything). Otherwise, no changes. It is not a true sequential system, as it uses stock engine management, and thus fires 2 coils at the same time, but most people I've spoken with say coil-on-plug is almost always preferable to distributors/plug wires for many reasons, including the ones John mentioned. My guy said he would be happy to make these for any interested parties.

Hi guys, this is Mike, im the one that made the setup for Brad. Id be happy to assist any of you with this or anything else you may need. I work for Ford.

Hi Mike,

My experiences may be of interest to you. A few years ago, as a consultant, I developed production-grade wiring harness for a Se7en (Superfomance S1) running a current (2000-) ZX3 Zetec EEC-IV system. I also developed a process to create this install and construct the harness in quantity (completely documented build documents). This work duplicated the engine management system that Ford had developed, but with the harness fitted properly to fit an in-line installation cleanly. The second step of this was to provide for tuning of the ECU using the EEC-Tuner of Erick Goehl. I reverse engineered enough of the EEC-IV Zetec manual engine binary so that I could locate the code to update the MAF calibration table and the injector size - i.e., enough to setup an engine that would work with output greater than could be supplied with the stock injectors. Other circumstances and the scope of the work overwhelmed me and I was never able to carry it forward to the extent I wanted. (sitting in my garage is a complete Zetec engine system, PATS and ignition key, harness down to the air-bag controller, ... completely dissected from a rolled 2000 ZX3). Anyway, as I learned early on and as you must know, the Ford system is simply the most advanced and sophisticated engine management system out there by miles, and offers tuning capabilities that can't be touched by any other system. I'd really like to at least pass on my learnings (and maybe even sell my engine system). Beyond all of that, it's great to know that there's someone else out there who knows what I'm talking about! :-)
