New D969 Coils
 

is there a group buy here? Are they a vendor here?

I don't think so no, they are based in the UK hence it being on our UK owners club forum.

Sorry if I posted in the wrong section, I just though people would want to know about them....

It is after all a performance modification :)

If you wish to just talk about it, that's fine. A post that just links someone else's group buy is assumed to be just advertisement for the group buy, and thus gets deleted.

The Link wasn't to the group buy, it was to the discussion and road test review :)

I can copy and paste from there if that is allowed?

What is the company name?

Rotary Revs.

They have had the D585 coils out for a while now. The D969 are the new version.

I am aware that for guys in the US you have the BHR ignition kit, although I am not sure how they differ....

Not only was the 3rd post an advertisement for the group buy, your original post in this thread was advertising it as well:
If you can separate the discussion from the group buy, then yes, by all means feel free to share.

Without having any actual knowledge of "D969" it possibly sounds like the version of the D585 with the limiter removed (hitting the internal dwell limiter can result in misfires/inaccurate timing, the actual dwell setting where this occurs can vary quite a bit which is where it causes problems). I have mentioned previously on the forum about this D585 issue and that those particular limiter-removed coils are available from Pantera EFI. They are a direct replacement for the D585. I doubt anyone paid any attention then ...




.

They are just standard D585's, they just renamed them D969's on their own. At least that is what they said on the UK rx8club FB group I follow.

lol, call Pantera EFI instead then ;)

I don't think so. They sell the D585 seperately. These are a whole new coil and use a different set of leads.

Chances are that if the terminals are different then it's a D585 variant with different terminals. A D969 doesn't seem to exist from what I can tell from a few cursory searches.

It's extremely unlikely that a coil designed for GM vehicles would go on sale in Europe before the US or Asia.

I'd appreciate a link to the original thread if anyone's found it.

From the link in my original post:

"So, much of a likeness and pretty similar on the outside, however they are hiding something. The specs are quite different, with the cores wound to make them a little more... shall we say, feisty. According to the lab test data, after only 2.6ms of charge time they will output a spark equivalent to that of a standard D585 charged for 5.5ms. That's a whopping 73mJ (typical) of spark energy delivered at 40KV, all with a dwell setting close to the RX-8 standard. There is headroom over this, meaning longer charge times can make for even more intense discharge.

Further to the red case, the second hint that these are not just standard D585 clones comes from the supplied ignition leads (Magnecor R100 10mm race leads)".

I can't post the original link and it will get removed again for advertisement... but it's on the RX8 UK Owner's Club forum.

It doesn't exist when you search because its directly manufactured by the same firm that manufactures the Delco D585. "They are a custom designed coil built into the D585 package. they are not from another vehicle and are exclusive to Rotary Revs".

they aren't the first to claim such, yet funny how they never actually post a dwell/output graph to back up their magic elixer marketing tactics

Needless to say I have a graph of a coil that was tested from a kit of another said supplier and it was nothing to be impressed about.

But maybe this supplier will handle it differently. The only thing on their website is a notice that D585 kits are out of stock. Not exactly inspiring to only see forum hype going on ....

Hence why there is a thread of the ongoing Road test and performance review. Phil is going to post up the results when he resets his dwell setting back to default.

The D585 are a really popular mod here in the UK so i'm not surprised they are out of stock in all honesty, there are always group buys for these.

they also come with a lifetime warranty on the coils, same as the D585.

Ok... So assuming it's the same link, I don't see anything that's really trying to sell the product in the first post of the thread.

From the Oscilliscope pictures they posted, it doesn't acrually seem like a benefit. Check it:

"D969"

http://www.rx8ownersclub.co.uk/forum...p?id=34785&t=1

Looking surface deep, the "D989" seems like it's producing a spark and that's it. (So naturally people are going to say it's better, blah blah blah...)

Going a little deeper, it seems like something isn't right. After the coil is fired, it seems like its working to do all it can to keep that spark alive, and you see a huge voltage drop through the primary coil, compared to that of the D585. This isn't necessarily a bad thing, but I can see it causing ignition problems as the spark plugs deteriorate.

Truck load of bullshit.

Not getting the same data display in both pictures so it's hard to verify.

What are you talking about?

Fuel pumps :p:

I mentioned this to Phil on the UK forum and he confirmed that it's actually a spike in voltage - the HT probe inverts the signal and so the trace is actually upside-down. His Oscilloscope does not have an invert function.

...It's really obviously upside down......I don't think anyone had that question....

And really? There's no way at all to invert the signal? Really? He said there's none? An invert function is the only way to do it? Wow, what has the world come to?

If he can't figure out how to flip the signal going into the such a simple oscilloscope I'm seriously questioning if he really knows anything at all about what he's doing.

It's nothing against you Kent, it's just important to be critical of new things to make sure they're anything like what people claim they are.
