Single ignition thoughts, or lack of thought??

[ekvh]

So my 1200 is like Joe's with the 1000 ignition on the cam. (But unlike Joe's in that it hasn't got C5 yet.) In reading up and in hopes of diminishing the flat four's loping, always seeming-to-miss-now-and-then idle, I was wondering of ways to get rid of that waste spark which happens in the exhaust stroke. Even the slightest bit can cause little poops of backfiring. The forced induction crowd say it's nearly a must. Since the 1200 has the ignition on the front, could I somehow rig it so the 1000 cam ignition would trigger two coils, say #1 and #2, then have the other ignition on the front of the 1200 fire two coils, #3and #4? If you took one magnet out of the Dyna, and removed the 3-4 module, you would fire 1-2 and then make a circle before firing again. Could the 1200 be modified to operate the 3-4 coils in the same way? It would likely require different coils as saturation time would double? But is this a way we could go to a single fire ignition? My head is spinning.

I have everything I need for this except the 1200 black box and whatever coils might be needed so they don't overheat.

I guess this would be Double single ignitiin.

hmmm smoking eric .....yes this was my question too eric not quite so huge though... ithink the c5 could be done to do it all ... been said too require four coils and set up difference that would cost a lot more .....but im sure it would be the set up to have

wow that's cool way to get it eric .....hmmm how about if you went electric fuel pump and moded the the cam on that side to mount another dyna ....that fuel pump gear is pressed on the perfect shaft for the dyna to work ... that would improve timing hugely ...and get rid of lots of flexi travel to involved in timing path .. and get single fire but I think thats sure kill to dynas probably as you stated hmmm

I think the magnets would stay, just remove the modules, one from the Dyna, one from the 1200. The bigger problem I think would be different advance curves, one mechanical and one computerized. The belt flex would still be an issue. Maybe the C5 could if the two maps were the same.

 

[joedrum]

yes I think that would be hard to deal with eric the two curves

 

[joedrum]

you spark me eric on this ....even two dynas with mechanical advances on both heads might be hard to deal with ... but both heads iggy equip got me spinning :headscratch:

 

[pidjones]

Would coil-on-plug solve the coils issue? Then all you would need is correct triggering, which could be done off of one C5 - the computer could handle alternating the sides based on the optical trigger. Would need some program work, but should be simple. I don't think it would perform a bit better, however.

From what I understand, coil on or msd need a computer controlled coil charge. Ours are too far in between pulses at low rpm that could would get too hot. I can't remember if the cam from the ignition side would work on the fuel pump side. I guess the better way might be trying to get four pulses off the crank. More to think about.

 

[joedrum]

no eric the fuel pump cam would have to be modified along with head doable I think but havnt look good yet

best way to eliminates wasted spark is adapt a distributor ignition. As I understand it c5 can be set to eliminate wasted spark.

 

[ekvh]

I thought I asked that, and the answer was no, for now.

I've been working on another area of the forum explaining basic ignition stuff.

Let me say:

We know GL1000's didnt pop when new. We know adding a strong multi sparking ignition will greatly reduce or eliminate popping.
Joe, Dan, and I talked about single firing the Wing. My opinion has been that it would be an overly expensive, overly complicated system.
If there is a way to stop or reduce this popping affordably, i believe that would be the best solution.

Gary from PowerArc and I have been discussing the cause. One theory is the unburned fuel ignites on the exhaust stroke (during valve overlap) and causes the pop. It might also combine with the other 3 cylinders to cause this.

If we burn ALL the fuel like we should, it can no longer ignite during wasted spark. It's not all theory, since i have seen at least four GL1000's totally stop this annoying popping after we installed the C5.

What we dont know for sure is why some Wings get better but are not completely cured. (overly rich carbs from leaking needle/seats??)

i don't have any loping or miss at idle with the stock setup, however i am interested in any info regarding running a 1200 engine with ignition off the left head, even points

Read the Hooch threads. Went from points to Dyna to C5.

ok tx!

are you using stock 1000 coils here? dyna?

thought the cams were left or right only deals?

read something at randakk's about using (selling?) a distributor

I saw that and last I heard he said it would cost too much for sell.

 

[slabghost]

Yep he said that is a one off not for sale.
