qucik question and it may have been answered i tried searching but couldnt find what i was looking for. is there a benefit to using a aftermarket coil like a AEM pencil, or the okada? what about useing then with a capacitive discharge ignition like the dis4 ect? i was thinking of using the aem pencils (not sure what size) and the dis4 but wasnt sure if it would work and be worth it.

I had burnt out the tach output on one of mine playing with a multimeter when I was building my sequential harness a few weeks back, otherwise mine have lasted 4 years now; so at least like 5,000 miles.The, um, coils work fine even if you pull them back a good inch from the spark plug - still runs. So I'm not that worried. :-)
Hey, are you going to sell just the plates? I've got a working set up, but my plate blows. Plate, nuts/bolts would be great, but I don't need the cops or the wiring. Then again, perhaps I will when I do my motor swap.

I dunno, for all I hear it's a 2 ms dwell time, I've run mine for years on... 4-ish ms? And it runs better the longer dwell I give it. 7 might be a bit much, but there's not a HUGE advantage to running them right up as fast as they will go. Try running yours longer, see if it starts faster, revs better, etc.
I have to agree with the longer dwell time. I just changed from 4ms to 2.1ms and I think the car ran more smoothly with the the 4ms dwell time.
With that being said, I also adjusted the dwell battey correction for the cops to be set to 2.1. I don't know what will happen if I change back to 4ms and leave the dwell correction the same. There was a writup where someone measured all of this info and 2.0 to 2.3 was supposd to be correct. I'll go back to 4ms today while I'm autotuning and then provide what I think.

for MS-II you should use 2.1 and this for your battery dwell curve:
6v 228%
8v 180%
10v 148%
12v 118%
14v 100%
16v 88%
when you put in the dwell number in MS-II you're telling it the max dwell at 14V, which would be 2.1ms. but we typically run less than 14v, more like 13.5v. So with the correct correction curve, this puts the dwell around 2.2ms running normally and closer to 2.5ms at 12v. This is the ideal dwell curve for toyota cops as tested by Jason.

Anybody notice a difference when the motors cold with these coils? Mine are a bitch in the mornings when they're cold. I'm getting used to it now but I have to ride the clutch taking off to keep it from dieing.

Specifically this link http://www.bmotorsports.com/shop/pro...oducts_id/1667
Turns out these folks are about 15 mins away from me.

Ordered the plugs from this company today... excited to do it properly without splicing.
Useful thread.... now to sift through the whole thing when i get time...
