Looking for Good Coilpack

I'm in the market for a good performance coilpack for my 1997 Legacy L. 2.2l. Bought an MSD coilpack but it looks to me like it doesn't fit at all. If anyone can point me in the right direction it'd be greatly appreciated.

/thread.

Heads up. My MSD failed after 4 years.

was the performance gain enough to make it worth replacing?

I've read on several srt forums that the OEM srt 4 coil pack is more reliable than the msd unit. I'm going to do more research on that before I pull the trigger on that upgrade.

$75 every 4 years? I'd say, "hell yeah". The only issue w/99s+ is that the ECU will sense the increased fuel burn & add more fuel to "correct" it. 98 ECUs do this too but the correction isn't nearly as severe.

4 years of service is pretty good for an aftermarket electrical part, msd is a good coilpack. The gains in fuel efficiency alone will keep one under the hood of my car whether I have to replace it every four years or not. You can't spend 80 bucks on one part and expect a 10 hp or 10 mpg raise, just not going to happen. Imo its the best 80 dollars I spent in the last year.

Great im a 99+

 

So is the MSD not as affective? Or should I start using 91 or something so the ecu knows it wont pre detonate with increased spark?

The MSD will still retain its effectiveness but you will lose an MPG or so with the bright side of a more responsive & linear power delivery as the fuel delivery increases to match the spark delivered. 91 is probably a little excessive. You're fine on 87. I've been using it the whole time & nothing bad has happened or will happen.

Oh nice. Im down for only power gain. That's what overtime is for, buying gas to burn! Haha

Its strange because I've never had the car respond the way its supposed to when you reset the ECU.

I remember a while ago you had told me how to do it.

Oh it responded but now you probably have a more linear power delivery. I know my ECU responded immediately & I felt the low end kick up a bit.

I haven't done this mod yet. Im just talking in terms of resetting the ecu...

 

Isn't it supposed to ramp up to 2k and settle down gradually? If so, mine never did that..

That's interesting about resetting ecu..how is that done, I still haven't had a chance to hook my car up to a scanner to clear my codes from that misfire, I'm sure the egr code is pending because of the delete, but I never knew an ecu reset could be done.

unhook the battery,

hold the brakes for a bit to purge the built up power,

let the car sit without a battery for an hour or so,

 

done

Like depress brakes and hold?

 

I tried that, I wonder if my car is different because of the lack of MAF goofiness...

Ill give it a shot again.. worst that could happen is nothing.

well, you're just holding the brakes to turn on the lights and get the built up power out of the system, you could charge your iphone or whatever too technically

 

or just pull the battery and let it sit overnight

Ahhhhhhh I see, sounds good.

Unhook the negative terminal.

Depress the brake pedal for about 30 "Mississippi" seconds.

Leave battery unplugged for about 1-2hrs.

Plug back up negative terminal & start car.

 

It should shoot up to 1800-2000rpms & then come down gradually to idle again.

Reset complete.

That's what I thought...

 

I want to know if my ecu is the same regardless of the fact it is speed density..

 

Or why my car is speed density..?

The same as what? Phase 1 ECUs? The ECUs for the Phase 2 engines learn more, faster than those of the Phase 1s. They're also more restrictive as they will literally try to learn around changes to spark, air, & fuel.

If my ecu is the same as a phase 2 with a MAF. I have no MAF and it has a MAP sensor on the drivers side of the TB

That's it huh? Sweet thanks.
