Default MSD Dis-2 ignition questions and such

I'm doin some research on the subject.......

I know Dave & Crazy Ken have these on their legacies.

I did see that MSD does have a HO version, however they said it was for drag strip use only.....so that's out.

Next real question is they said I would need this tach adapter that would send feedback signals back to the ECU, so it would know when to fire the injectors and have the tach display a value.

Do I need this thing.......no one has made mention of it when installing the Dis-2 on their subie. From what it sounds like, you just strip back the wire goin to the coil, and tap that into the Dis-2 unit......unless I'm wrong about that?

I've read some other nay-sayers that clain the Dis-2 unit does nothing, don't waste your money. I'm inclined not to believe them due to how the product works and such.....there will be a gain.

Any feedback, comments from those of you that are runnin the Dis-2 would be appreciated, especially about that tach adapter thing.

The adapter is not needed for Subarus, iirc, it's only needed for some DSMs and other cars. The manual states this.

As far as improvements...using a Diamond coil, Magnecor wires and Denso Iridium plugs, i noticed a marked improvement everywhere in the powerband, and a nice fat torque boost on the bottom end.

There was a single event, however, that convinced me it worked:

The night of the installation, when driving home, i had to blast through a yellow light, next thing i know the car is bouncing off redline in 2nd gear (still had my automatic at the time).

This had happened only once before, while on an autocross course.

After i installed the DIS-2, i could easily get the car to hit redline in 2nd before the transmission would be able to shift up, that's how much smoother and faster revving the car was.

Never regretted it.

coool......thanks Dave for the feedback.

I've got the magnacore wires, have the diamond coil pack on its way......and hopefully soon to have the Dis-2

Apparently the tech guy I talked to didn't know ****....

Oh well......there's lot's of stupid people out there.......hahaha

I've only bounced off the rev-limiter once on my car......I think it was in second........I was driving around in second was at about 4-5000 rpm......dumped it.......and it bounced......sorta freaked me for a second there......never had done that before.

Question

What's the Diamond Coilpack? Is it just a replacement coilpack? If so, from which manufacturer? Thanks guys.

The manual trans cars got the diamond coil pack

The auto trans cars got the hitachi coil pack

This is for the 90-94 legacies From 95 on....they all got the diamond ones.

The diamond ones can handle more juice then the hitachi one when upgrading to a better ignition system.

Prob not a big deal unless you upgrade to the Dis-2 unit

Any reason for not using the High Output model? They are only usually 10-20 more dollars more. I guess it would mean shorter life on the spark plugs or?

Also for the diamond pack is the correct part number 22433aa240 which has been replaced with 22433AA370? Why did only the manual tranny non turbo get the higher power handling model while the turbo still got the "weak" unit?

Where has everyone else mounted the unit?

The HO version is not for road use.....I have called MSD, and talked to two different people and they both said you would run into heat issues in running it on the street. They said the HO version is only for drag racing use, where you're not running too long.

I don't know why the autos got the Hitachi coil pack. All the autos, including the turbo versions got the Hitachi ones....up until 95....after that.....they all got the diamond one.

I think dave has his mounted on the firewall. He prob has pics on his site. I'll have to take a look how big it is and see where I got room.

Cool, so anywhere cheaper than 320 through summit? Ive been thinking about this for along time and you have sparked my interest again. After reading DLC'S comments Im ready to try it out.

So the recipe for the "best" ignition system seems to be

NGK plugs (copper for higher perf/reduce life)
Magnecor 8.5 wires
Subaru Manual transmission coil pack
Msd Dis-2 part 6211

Now with this setup (as it seems to be somewhat common) what kind of gap have you ran on the plugs?

I did some searching....didn't find anything cheaper then 320. There is a guy that is selling a brand new one for 300 shipped....he is in SoCal.

I figured for 30 extra bucks.....I'd buy one from a retailer where I could return if need be......just my personal preference.

I'll find the link and PM ya.

I'd just run stock gap......you could run on the wider side of the gap....but I wouldn't go outside of it.....

I copied another guy and just stuck it right against the firewall on the driver side, with a single screw holding it in, but some padding underneath to keep it from moving around and getting damaged. There's really nowhere else in the engine compartment to place it.

Nico - The Bosch Platniums are o.k., but the -NGK copper plugs- are tres bien! Je crois que oui.

Je ne sais pas 'nology wires', are they like Magnacore Wires?

I'll have to leave the MSD question on the pins to Dave.

The only things the DIP switches will do for you is let you set the redline, some staging redline stuff, soft rev limiter...nothing power related, it's doing everything for the car all the time.

Ill try to say this in the nicest way I can, the Nology wires are not very good. You would be far better off purchasing standard wires that need replacing every couple years. Of course different manufactures are going to say bad things about the competition but read about the nology wires on magnecors site.

Here is a qoute from the magnecor wire faq http://www.magnecor.com/magnecor1/truth.htm

The most notable of exaggerated claims for ignition wires are made by Nology, a recent manufacturer of ignition wires promoted as "the only spark plug wires with built-in capacitor." Nology's "HotWires" (called "Plasma Leads" in the UK) consist of unsuppressed solid metal or spiral conductor ignition wires over which braided metal sleeves are partially fitted. The braided metal sleeves are grounded via straps formed from part of the braiding. Insulating covers are fitted over the braided metal sleeves. These wires are well constructed. For whatever reason, Nology specifies that non-resistor spark plugs need to be used with their "HotWires." In a demonstration, the use of resistor plugs nullifies the visual effect of the brighter spark.

Ignition wires with grounded braided metal sleeves over the cable have come and gone all over the world for (at least) the last 30 years, and similar wires were used over 20 years ago by a few car makers to solve cross-firing problems on early fuel injected engines and RFI problems on fiberglass bodied cars only to find other problems were created. The recent Circle Track Magazine (USA, May, 1996 issue) test showed Nology "HotWires" produced no additional horsepower (the test actually showed a 10 horsepower decrease when compared to stock carbon conductor wires).
