Sounds good. I am one of the people that is currently running the COPs on my stock 99 ECU. I haven't noticed any overheating of the coils, but haven't been driving it much since the swap due to the winter. I am interested in seeing what you come up with.

Nope, I'm running a 1995.5. Car runs perfectly with factory coils, won't fire with more than 1 coil hooked up per trigger circuit.

The overheating will happen at sustained high RPM.

Thats what I was worried about. Thankfully, I do not road race the car, just autocross, so it is minimal (there is cool down time). I would still be interested in a solution to the dwell difference.

Wouldn't a small series resistor help without doing too much "damage"?

JasonC SBB 02-17-2008 10:50 AM

Won't work very well.

I would still be worried.. I run a two driver car and at some auto crosses it feels like I'm hot lapping the car.. :bang:

Anyone blow the 15A engine fuse with the COPs hooked up and the ignition in ON/RUN?

I was pretty careful with the wiring - did continuity tests on everything to make sure what should be connected is and what shouldn't be, isn't. I'll be more careful next time I hook it up in case I blow the fuse again to see what caused it.

Nevermind, I'm a dumbass. Hopefully I didn't fry the COPs, too.

After swapping the ground and power wires in the harness (don't ask) I fired it up this morning. I didn't put any load on it, but it started and revved to 6k rpm just fine after warming up. All that's left is to seal up the wiring harness, put the bracket on, and go for a test drive. Should be an exciting evening.

:yippee:

AbeFM 02-19-2008 01:08 PM

heh - yeah, I did the same.... Stupid bigger wire for power than ground stupid thing.:mad:

pull that damn coilpack out of there!

Saml01 02-19-2008 10:53 PM

If you guys need weatherpack connectors, I just bought some from this guy. Really helpful guy, and really fast with shipping, his prices are also the best I have found.

I will after it runs for a week. My wiring jobs usually suck so I'll be carrying my plug wires and laptop around for a few days just in case.

Anyone know if the 4 pin connector on the passenger's side (96/97) for the coil packs is providing signaling for something else? Sure would be a lot cleaner to get one of those connectors rather than hooking up to the coil pack connectors.
