beerslurpy: Since this is a conversion just cut the miata harness. Leave 4" on the Miata's coil plugs just incase you ever want to go back. Just to note. If you follow the wires from the Miata's coil plug back into the harness a few inches you'll find they all connect together except for the triggers. In other words there's only 5 wires you'll need from the Miata. If you want, open the harness and find where they tie together. You can tap the 5 wires (cut insulation, twist, solder, tape) and leave the oem connectors there.

 

rut roh. Where you been Sean? I tried calling you a few times. What are the plugs looking like?

 

Dunno if it's already been asked, but do the Toyota coils seal the tunnel like a set of plug wires do? You know, to keep water and random junk out?

 

To some extent. The rubber seal does contact the valve cover but is not molded to fit as well as it might fit the 1ZZFE. I personally don't let water and random junk get on my motor. :gay:

 

I knew whatever response I got would have that sort of disclaimer in it...

Thanks for the prompt response!

 

Red90:
I don't see the dwell being a huge issue. I goofed with it quite a bit and it seems to either ignite the mix or not. I couldn't feel any change in performance when I cranked up the dwell. There is a science to it and I won't argue a long hot spark is good for power. What we need is the guy who tested them, Jason?, to run them for a few hours with excessive dwell at excessive RPM and see how hot they get. Or even run it till it blows out to test the limits. (I'll send him one of TurboTims for that testing....j/k). He noted the current limit was 10a which is more then enough to warm up those little coils IF the dwell was excessively long. So how about it Jason? You want to abuse some coils for awhile?

Ah you know us well.

I should tell you that I had recently painted my valve cover after welding on the stand-offs for bolting the COPs down. When I removed them there was a full circle from where the COP seal was in full contect with the valve cover. I guess I could have let it dry a bit longer.

 

that's good news. I think I might try this.

lazzer, back on one of the early pages (I just read 1-7 all at once. Yes, I'm bored.) you say "tie the power wires together" and "tie the grounds together". I assume you're saying the COPs share a common ground and common power wire?

 

Uh right now I only have 6 wires at the connectors. I think my year lacks the RPM signal.

 

I realize that, but electronics are subject to wear and tear as well. That's why computer components go bad over time.

Also, any MS guys running this yet? I plan on going MS and if sequntial fire can be achieved that would be neat.

 

I would liked to have tackled this project already, but have had other delays.

 

Once my MS is fully tuned to my liking, I will be running these on sequential fire.

In less then 2 weeks hopefully.

 

Yes.

 

This explanation is by far the easiest IMHO. Makes it sound easy.

 

So when am I going to get my coils? Tracking number would be fantastic too.

 

Seconded on the tracking numbers.

Oh and for 97 it looks like there is no tach line so you end up with:

3 wires per coil on the COP side.
-1 each of trigger, power and ground per plug

4 wires on the miata harness side
-2x trigger, one from each factory ign harness
-1x +12v
-1x ground

I have the GM parts on the way and I have the aluminum for the bracket to hold the COPs in place. When the coils get here, I am going to drill it, find some appropriate sized bolts and some spacers.

 

I haven't even got my tracking number yet but the order was placed. Everybody's coils will go out the same day so I'll post all the tracking numbers here. Or is that a bad idea because the addresses might be shown.

 

Better PM the tracking number IMO.

Not that I care if you guys drop by :gay:

 

UPS only lists the city it is going to. They won't be able to find out where anyone lives. Otherwise thieves could just troll the tracking system looking for packages taht are being dropped locally to steal them.

 

Lazzer you got my PM about the address change?

I work at ups, Ill make sure *I* get all the coils haha.
