Just want to see what the general opinion is on what ignition systems you all are using. I know B-series ignitions can hack upwards of 450+ horsepower, but for those of you that run aftermarket ignitions, what are you using? Post setups, pics, if available.

i'll be running a coil on plug setup using an M&W ignition box, probably use an msd dis-4 until i can get the m&w or the msd breaks (no offense but they do, lol)

I made 676whp and had an MSD Digital 6 ignition with Blaster SS coil and stock wires. The thing that sucks about Honda's is the dang Ignitor that goes bad all the time!!!!!! I said forget it and went with Coil On plug on my new set up. 4 CBR 954RR coils and AEM C2DI box(cross fingers I have no probs).

Msd 6a with a blaster 2 coil. It doesn't have the rev limiter option or the timing option, but it definatley delivers much more spark than stock. Real over kill. At night, you can pull the boot from one of the plugs and watch it arc 7-8" from the valve cover. I once (cause Im a moron) took the coil line off while the car was running and WOW, did I get thrown back! I know that it's over kill and just cause there is more spark doesn't mean it's necessarily better, but im impressed with it effectiveness. It should support anything I throw at it.

BlackPhoenix, since you seem to be an insider at MSD, would you mind commenting more on the DIS4 boxes? I've heard from *several* people of DOA type failures. I've not heard of very many long term failures, but then again I haven't heard of many long term DIS4 users. Is MSD aware of any problems with the DIS4 boxes that might be contributing to their current marginal reputation? Do you encounter a lot of problems with them in the line of technical support?
I'd love to hear that the DIS4 is a solid product, because the AEM C2DI is certainly scary at this point.

On my turbo car I use msd digital 7 plus, msd cap, wires, pro power hvc 7 series coil. On my all motor car im using msd digital 6, msd cap and wires, and blaster 3 coil.

Might want to change that 450+ to 600...

Lol, insider. I'm just a Technical Support guy...but the reason I posted this was specifically to help out import guys with our ignitions. Currently, I'm the ONLY one who does Sport Compact, so the segment with the company could really use a boost, and that's what I'm aiming to do.
Anyway, the DIS 4 is a solid unit. I do realize that a lot of people have heard that other people run into problems with MSD units, however R&D is working on tracing down specific problems people have, especially with digital units. We haven't really had a lot of tech line problems with the DIS 4, just more of application questions, i.e., "can I run this ignition on my...." It's a good unit for people who run stand alone engine management, and need an extra edge in the timing department.
The most common problem people have with MSD ignitions is the lack of attention they give to wiring. The boxes require solid connections to battery and ground, and if possible, the heavy black wire should be run directly to the battery. The light red wire (switched power) shouldn't share a circuit with anything else, such as a stereo or amplifier, for the fact that radio noise may occur. All input and output wires should be loomed separate from other engine wiring to reduce the chance of EM interference.
Just out of curiosity, blundar, the people who you've heard the problems from, are they running this ignition on a Honda?
Again guys, I'm trying to bring up the Sport Compact segment here at MSD. Any input is appreciated. If you all need any help with your setups, feel free to PM me or call the Tech Line.

Thanks a lot for the response! The failures I heard of were DIS4 boxes used in conjunction with AEM boxes and honda CBR coils on turbocharged B series motors. When the DIS4 box was replaced with another spark box, there were no further issues. Diagnosis: DOA.
The person who relayed this to me knows how to wire and install these things. I'm 99% certain it was a genuine failure.
I'm interested to try a DIS4 now. Thanks.

Which AEM box was the DIS 4 used with? What application are you going to try it out on?
Your welcome for the response. Let me know how it turns out for you.

im going to be using an aem 1000 box with the dis 4 using a coil on plug setup and share the same concern with unit failure.
also with the dis 4, does it use a 12v + to trigger the coil or does it ground out the coil to trigger it?

Same here; I would like to know the issues related to the DIS-4 and DIS-4 HO boxes.
AEM CDI is pretty much out of the picture AFAIK...
I've then switched to the DIS-4 and it failed after a day of driving.
I've then purchased an MSD DIS-4 HO and it failed again. Although I am using an AEM EMS, the MSD DIS-4 was wired in after a Bosch Ignitor just the DIS-4 was meant to be installed... Also, the first MSD DIS-4 that I had was still on stock ECU so it wasn't AEM EMS related...
I appreciate the great tech support of MSD, but again, time is money and each time I send something back to MSD, I am looking at a month downtime with shipping things back and forth across the border (from Canada to US).
It would be great if we can find out the cause of the failure other than being in the dark
Oh, to add to this thread, I was running a MSD 6-AL with Blaster HVC coil and distributor cap with MSD 8.5 mm wires. Worked great for 5+ years. Like most Honda guys, the ignitor keeps dying though and I had them replace them every 6 months or so.
