The Chevy LS V8 engine coil packs are popular to use for COP setups also, might look at them for ideas too. |

The GM LS "coil-near-plug" units are also pretty stout. I've read about guys using stock coils on turbo motors at 20+ psi boost. @ Pierre, if you're using Ford 'Triton' COP coils, be sure to have a spare (or 6). I see these units go bad all the time. The internal insulation breaks down & energy from the secondary windings bleeds into the primary circuit under load. Mild case will just be misfire. Medium case the feedback "spikes" the pcm causing severe hesistation & "glitches". Severe cases can damage the coil drivers in pcm. |

Good to know. That could happen to any coil though. They are all basically the same design I imagine. In the future I want to do away with the edis modules and use the smart type coils driven directly by the megasquirt. I would have probably done that now if I didn't already have the ford coils. |

You want better spark control with a sequential cop setup; Doesnt that entail a cam speed sensor and isnt any cam speed sensor going to be driven by the sloppy timing chain? ford Edis is crank driven, rock stable, no chain whip. I could see cop off a 2:1 gear drive but i dont think the chain driven cam position sensor is ideal. Belt drive is close enough. What would your ideas be for a accurate cam speed sensor, or is this a wasted spark cop? Then my next question would be the benefits of a WS COP project. |

Many engine brands that use a cam sensor in conjunction with a timing chain also use chain tensioners. Maybe thats enough to satisfy the computer and not trigger false signals or cause glitches. |
