2000 coil rail options ???

Has anyone thought about using 6 COP's? Does anyone know how the factory coils are wired(single spark, double spark, etc)?

Re: 2000 coil rail options ???

Does anyone know if the Viper coil is dual spark? My Haynes diagrams would leave one to believe the factory coil rail is a dual spark set-up.

Re: 2000 coil rail options ???

The factory coil is wiring up in a wasted spark configuration with 3 ignition drivers in the PCM driving 3 coils. The Viper coil is the same (Even has the same connector). As for doing Individual COPs, you have to remember the factory coil is driver is integrated into the PCM, so you can't get a logic level out to drive smart coils, like an LS1 coil. But if you could managed to get a pair of dumb COPs that have the same resistance combined as the stock coil, in theory it could work.

Re: 2000 coil rail options ???

Well I don't have any plug wires now and I prefer not to go backwards in time. Yes, resistance for most COP's is to low for the PCM drivers but, there's ways around that to. I will keep looking for a unit that will work or even look into building a power supply/splitter!

Has anybody tried the Screamin-Demon coil or have a part# ?

Re: 2000 coil rail options ???

I called Performance Distributors today. They said that the #31740 coil (JK) is the same one used in the Viper kit. What I did learn in addition that it only has a .621 ohms pri resistance which is a little low for my comfort level. I'd like to order a stocker (JK) and see what the resistance is on that?

Must be the older JK that uses the single coil

My 2015 JKU uses COP

Re: 2000 coil rail options ???

I received my JK coil today(no markings on it what so ever). The wire configuration is the same as the XJ. The pri resistance measured out at 1.1 ohms. The weight is heavier than I thought but I can build a heavier bracket! I will also reverse drivers 1 & 3 to get a better spark plug wire layout(with the connector facing to the rear and on bottom).

Re: 2000 coil rail options ???

It would actually be drivers 2 & 3 , I want it to wire out(top to bottom with the connector facing rear)....

3-4
1-6
2-5

Re: 2000 coil rail options ???

I'm stalled on a couple other projects right now so I played with the coil some more. I received my Airtex adapter and it fit my jeep but I will have to remove the "white" rib on the coil connector. I painted the coil input/output's(red/white/blue) when I was testing the coil so I'll know how I want to configure the plug output's. It's a little hard to see in the last pic, but the pin-out is red/B+/white/blue .

In a attempt to identify the terminals I took apart the adapter!

Re: 2000 coil rail options ???

Worked on the rough cut today (easier to take it away than put it back, and not bad for a one arm guy). Tomorrow I'll start fitting the spud material because the mounting bolt's are at 45*.
