HONDA DOHC B16A DSD-2 (1G) Installation in 3 minutes.

[SloS13]

I can do a COP conversion on my miata in about 45 seconds.

[Joseph Davis]

I wonder how many people know that, without a CDI box, that's a performance downgrade.

What are the advantages of installing COP?

Possibly homosexual late teenage boys become impressed when you pop your hood in a parking lot, and give you their phone number for friendship with the possibility of a long term relationship.

So there's no advantage? 

Why do they install them then?

You may be French-Canadian, sir, but I am proud to point out that your failure to understand why is because you are a heterosexual.

Glad to have you on our team.

So JD does that mean you will not be making the COP kit you talk about a while back. 

I take it if I found a D17 sitting in a JY I just take the COPs and harness.

Then re-pin the harness then I could run this on any 1g or 2g D-series?

Would this affect how Crome adj. Ign. timing with COPs?

I my area I could sell a conversion service for some serious cash. :yes: ;D

So what is the total scoop here? ;D

Fawking french Canadians.

It's a simple Demux.  There will be a slight propagation delay (of course) from having the extra circuitry intercepting and distributing coil signals, but with cheap modern circuitry it'd be minimal to the point of being unnoticeable since Mhz clock speeds laugh at slow motion automobile engines.

So my thought of using a D17 COP set-up is correct? ;D

[Joseph Davis]

Only if you want something as crappy as the K-series COPs.

[Joseph Davis]

I'm being serious.  They misfire before a stock distributor-era coil does.

Is the 90's dizzy/coil honda combo really that fuckin good?

[dvst8r]

Is the 90's dizzy/coil honda combo really that fuckin good?

Or is the K / D17 COP really that bad?

Off the pallet JDM H22Dizzy got me 618WHPzzzzz with no issue at ALL>

The old coils had a lovely dizzy housing with which to transfer heat out of the coil.  Plastic cant do that.

Oh yeah, fuck you. I knew putting the ford COP setup on my miata would be better than the shitty coilpack and plugwires the older EDIS system used. I mean, COME ON, no way ford downgraded their ignition system when they went to COP....

Gapped the plugs at .035 and it wouldn't go over 2 PSI with the COPs once the coils were good and hot after driving a while. One day I got pissed cause it was fucking up and pulled them off and plugged the coil pack and wires back in. Worked fine ever since even at 16 pounds and .035" gap.

The new Ford COP are fantastic, but if they are being driven by something that does not feed them the correct dwell then your results WILL vary.  This is not just a claim I make, work with inductive reactance and calc the charge times of inductors as they change with frequency and you'll see.

Yeap. I guess I could send you one of these modules like we talked about...

Do it!

even with discreet, if you use the right parts the delay works out to around 0.25 degree at ~14,000rpm.

any thoughts of just using a cdi that doesn't suck and put the splitter on the output side of it. IGBTs are cheap. so are bike coils. or split the signal in two and feed it to an ARC-2.

what are your thoughts on the 350z coils? i've heard good things, but i'm sure there are some bad things floating around that i haven't gotten to yet..

i need to quit thinking about this shit and finish my brakes.

[Joseph Davis]

I haven't heard anything, but I did tune a Turbonetics kitted G35 with the UpRev reflash software.  The "stock" Turbonetics reflash freaking drowns the motor with fuel but it doesn't misfire and the combustion chambers looked super clean.  I still have a weird mentality towards the (pussy rods in the) VQ35DE, but overall the engine design and the ECU system is pretty sweet.

I'm wondering if the whole DIY CDI thing needs to be revamped for the modern age, and have a cheap CPLD act as the demux so you can flash different ignition profiles to a generic unit.  The problem with doing that is I won't be able to scoop up CBR coils and clips on eBay for $20 shipped anymore.

a DIP switch that changes which output of a decade counter ties to the reset pin could effectively change from 1-10 cylinders in either wasted spark or direct fire..
