Re: Turbo Miata Build Thread (56K-Not Today)
Hmm. I'm definately gonna have to get a noise suppresor. Checked walmart a while back and they didn't have any. But they're online for cheap so I'll order one soon.
As for wiring in the coils, the coilpacks I'm using are mazda Millenia COPs. They came off a motor that ran 14 pounds from the factory, so I figured they should be pretty stout. That and they were 12 bucks with connectors.
But I'm not sure on just wiring them up like you said. These are "smart coils" IE-built in ignitors. So These have 3 wires to each coil instead of 2. It's got Gnd, +12V, Trigger. +5V to the trigger will fire the coil. Pretty sure that's right.
Here's a pinout of my COPs.
And how would I rewire EDIS for rev limit and anti lag? Also I readup on EDIS and COPs after you mentioned it and I'm reading that pairing up coils affects dwell and all that too. And tha some would run two EDIS modules to fully charge the coils. IE-still wasted spark, but each coil has a module that charges it.

---- you know what, I never thought about how it will affect dwell. Hrm I would also hate wiring in a 2nd edis unit, the thing is stupid I hate it and its a pita. I can't remember where the anti lag writeup is, youlll have to find it. Ill do some poking around and see what I come up with.

Yeah, I'm afraid to go ------- with it to try something that's new and kill an ignitor or coil. Only car at college right now. This summer I was planning to ditch the EDIS and let MS read the VR sensor directly and let MS fire the COPs. So unless there's an easy way to do it now, I'll just wait and do it this summer. I should have just done it that wasy from the start. I used to have MS firing the miata's factory coil pack and launch control and flat shift were FUN. I miss that..
But I will definately be installing a noise suppresor soon. That would be awesome if it cleaned up the signals.

I'm running around 176 kPa right now. So that puts me around 16* at peak torque climbing to 18* by 7Kish. I can probably add in some timing, especially around 7K. Most add in 4-5 more degrees from 5K to 7K.
As soon as I'm home for summer I'm gonna crank the boost up wicked high and see what this stock BP will take.
Might have to get the 4 bar map sensor so I can go over 22 pounds.
