Jordan got the Dynospark free for "evaluation". I've discussed this a long time ago right after he got it - I don't think he can give an unbiased review on it; not that I think he'd do it on purpose, but just because of human nature.

I was looking at the LTCC myself, but wasn't particuarly happy with all the wires everywhere. After seeing several people's websites of their installs, I really didn't like all the wires.

I opted for the Delteq instead. I personally prefer the lost-spark setup (larger coils have the potential for more spark energy even when the non-firing cylinder loss is taking into account), and I wanted to make my ignition system as simple as possible (it replaced an Electromotive SDI). I have some pictures on my website:

I haven't taken any completed pictures yet, but the car is back together and running great. Hopefully this weekend will be nice enough for me to back the car out of the garage and take some good pictures.

 

Looks nice and tidy. Especially with the plug wires not plugged in.
How much was this? $1,000.+?

Does it still interact with the stock PCM?

 

Hey Curt, Did you try to mount the coils anywhere else? I personally dont like the ontop of the valve cover spot as it doesnt look that visually great to me. I was thinking about the open spot near the fuse box. Any thoghts?

 

yea, can you explain to us or direct us to a place that explains how the setup works. I'm interested...

Beautiful system!

I like it infinitely over the LTCC setup. Sorry LTCC guys! But, less wires and a full system offered. For under $700 thats great...

 

Dirty - well under $1000 for their complete turn-key setup. However, I didn't buy the entire system from them. Since I was using a system that used the exact same coils, I used the new MSD coils I had just ordered from Summit Racing - those are not what comes in the kit. The MSD coils aren't any better though IMO, I just happened to have them sitting on my work bench; I had intended on installing them on the SDI but never got around to it. I also didn't get the plug wires from them either - I thought I could use my fairly new Magnecor wires since I was putting the coils in the same spot. However, they sit in a different order and I didn't like the way it looked so I replaced them with a new set of Magnecor's. I believe the wires they include are made to fit in the stock looms (under the exhaust manifolds/headers); they sounded very nice though.

kmook - no, I didn't try to mount them anywhere else. With everything in place and cleaned up, I think they look good on top of the valve cover. Hopefully some pictures of the completed project will show that. I have always tried to take great care in aesthetics. You could feasibly mount the coils just about anywhere you want, but the plug wires would have to be really long to reach all the way over to the corner where the original airbox was. They do have a kit that mounts the coil pack on the radiator fan shroud though. Haven't seen it in person, but that might be what you're looking for. I thought about it myself, but decided against it mainly because of how I had the SDI mounted, and because I didn't want any spark plug wires to be in the path of the serpentine belt - it can do a good deal of damage if it comes off the pulleys.

scooby - it replaces the stock ICM, high-tension side of the Opti and the stock coil. Everything except the Delteq box is off-the-shelf GM parts. The coils and ICM (the black plastic base the coils sit on) is from the Northstar. It doesn't add any new functionality; it uses the stock computer to control the coil packs. It's a great system that does what it's supposed to do. Like I said earlier, I wanted to simplify my car so I could enjoy driving it again. If you need more options on the system (window switch, timing retard, soft-touch rev limiter, etc) you can add the standard aftermarket boxes (like MSD) to it.

 

I haven't examined it completely, but it looks like it includes everything to implement it, correct?

I think thats the best part!

 

You can buy a complete kit, or you can get a "bare bones" setup. Give them a call (or drop them an e-mail) and they can tell you all the options available. What I bought was basically a bare bones plus ICM. They include all the hardware too which makes it really nice to install.

 

As long as you understand GM already had the DIS ignition available, when they designed the LS series engines. You can figure they had a good reason, i.e., felt it justified, to spend the extra/additional financial investment, to design/engineer, the 8 coil CNP setup, over utilizing the 4 coil waste spark system they already had. So, no need to apologize. Just a little FFT.

 

If I were to buy the barebones kit, how much would I be looking to spend on the coilpacks and where could I buy them from?

 

Yes, but either of those are better alternatives than the optispark utilized.

 

Yes but it looks a lot better and easier to work, troubleshoot than the LTCC.. The LTCC is massive in wires.. it will require a lot fo work to just make it unnoticeable.. maybe modified fuel rail covers to pin down all those wires

And a few splices also...

 

Are there any coils from the ls1/6 engines that won't work with the ltcc and do all of them require "opti" style conections?

Also what are some other sources for the coils for the Deltec system besides the northstar?

 

i called around to salvage yards and found the northstar ICM and Coil packs for aoubt $100-150 used.

the DIY kit from delteq is $350.

then you need some cut-to-fit wires, and make your own mounting bracket.

i *think* thats it.
