[QUOTE="Rednaxs60, post: 229907, member: 4617"] COP units and pigtails have been delivered. The in-line spark tester as well. Have the engine idling fairly well, engine stumble is being addressed. Fuel is sequential so this mod will finalize the install. Did some reading and socrace used some plug wire to go between the COP and OEM plug cap. Peel the plug wire insulation back, spread out the internal wire, and fit into the COP stainless steel spring, just like in the old days of distributor caps. COP units are marked for positive and negative connection. COP dwell will be 1.5 ms with a spark duration of 2.0 ms as per socrace findings. Have to figure out how to connect the CFI covers if this works well. Will check engine timing before staring it. Only other mod to this install is a baro sensor. Have the components required on order. Had the engine started for some testing/tuning of VE and spark. Increased RPMs in increments up to 4K. MAP reading is pretty linear going across the VE table, did drop to 50 kPa. Adjusted the VE table cells, operating a bit rich. Returned to idle nicely. [/QUOTE]
