Re: Coils
At the moment theres no proven coil better than the C-REV coils with the field time, but theres always something round the corner! Too much money as well for a red counter stuck on the top! They do have an output chart, which looks great, but we can all talk bull if we have too i supose.
Whats the weight of a OEM C-Rev coil????
I've up dated my comment as on reading did come over as a bit harsh!!!!

Would love to hear the criteria and research in coming to this conclusion.

Re: Coils
I think Carl's point is valid. You made a direct statement of fact, but without supporting it at all. Carl has spent a huge amount of money developing his unique coils. He knows his product, and he knows the Mazda product. If you state that RRP's coils are definitely inferior then you need to say why. If your argument is simply that RRP's coils are, as yet, unproven in the market place, and too early to the market to be sure of their long term performance, then that's a different point. Carl is confident of his product, following considerable design and development, specifically on RX-8s (not small block Chevies!), and I know his coils have done many thousands of development miles. Any product that is new to the market is, by definition, unproven in the market place, but I do think these coils are as "safe" a bet as any product can be, and certainly don't deserve to be dismissed.

Re: Coils
No for one I don’t have to say anything as the is a club forum! yes Carl has spent lots of time and money and if you read the posts previous, I have never said anything bad about Carls coils, so lets not be super critical here and if anything I think I’ve even said I’d hopefully get some, but not after this reaction, which frankly I don’t care for!
Yes, I have had several discussions on coils with others, however that’s not on here! It does seem we can’t say anything different on here either, which is sad!

You can say what you like (within reason). No one's moderated your comments, or reported your post. If you want to make statements of fact then you have to be able to back them up, or get challenged.

Re: Coils
I'm sure you'll understand a forum isn’t the most sensible place for stating facts!
OK where is the proof of the Carls coils being better?
If the test has been carried out with all the coils to prove this where is it!
The test can’t be carried out with anyone with an interest of the product or any attachment! Testing to be done with all coils being in a new state and the same car on the same day with controlled protocols and rest time between testing programme!
We seem to be very bold on the next best thing and people should look back about the D585’s , which were the NUTS!
It’s great to have a forum with guys like Carl who's obviously passionate about his work and he should be as he’s got some cool things and what looks like hard as hell work to get where he is!
I email those guys about those plasma coils and they got back very quickly, which it was nice to see great customer services! Holly poop anyone want to be an importer FFS!

From your rationale, no aftermarket coil could be better than Mazda OE coils as we simply just cannot sell enough, the idea that I have to sell as many as Mazda to even be considered as a comparable product is unfounded and to me at least does not make sense.
My coils have been tested for output, obviously by the factory that manufactures them, the specifications are on my website for all to see. I've also tested them for over 5000 miles on the platform they were designed for, stressing the coils over and above their specified rating. Still no failure, the original Mazda coils were failing at this point.
OE coils specifications are well known and my coils output pretty much double what they do in terms of spark energy. It's arguable whether this is required but this is a fact.
As for independent testing I have offered Phil Bate (a long standing well respected member) a set FOC to do a full independent test and review. He has accepted to do this but unable for another month or so.
Finally, if you are going to make a statement (yours was a statement) then all I'm asking is how you came to this conclusion, I'm willing and open to hear and then accept your findings if they are on sound footing.

Re: Coils
How many miles does it take for a Std C-rev coil to fail?
I think we've all made statements about other products, which are unfair, but the best thing for you is to shut the sceptics up and push on!
Hey I’ve gave up on the motorbike coils total dead end and it would mean a stupide harness adapter!
Is Phil Bates doing others that would be cool?
Was the failing coils new like yours?

Re: Coils
I don't think it matters how many miles a C coil might last. The point is that they don't have a lifetime guarantee.
I run Mazda C coils (RRP's new ones weren't available at the time) and come replacement time my options appear to be:
-Paying more for new C coils with a known shelf life
-Paying more for 585 variant coils which need a custom fitting/may have a guarantee but sometimes fail/need mapping to get the best out of them.
-Paying less for coils designed for my car that fit natively, from a local (to me) manufacturer that I trust, with a lifetime guarantee (so who cares if one fails).
It's a non-debate on coils now as far as I can tell. RRP have cornered/undercut the market unless some flaw or weakness is exposed.
And those eye wateringly priced coils linked earlier... I hope nobody ever wasted their money on them.

Re: Coils
Yeah mad money!!!! but if you become a seller its free shipping FFs
There fitting instructions are worth it!!!!!!
Just looked at the D585's they don't need a Map and are plug and play! ok got a stupid harness, but for a NA car they give all the bang needed! With an option to tweak if you’re going down the forced route!
Can someone tell me how some D585's are very reliable and have no real fails and there’s some that are really bad! Is there cheap version out there that might be used to make money for the greater good!
If a coil fails and kills your motor does that get fixed too?
Now cheap and if they work then https://www.surefireonline.co.uk/MAZDA- ... x8-blk.htm
These are the bad boys I was given (I thought they were NGK), but remain on the fish tank! Has anyone measured how heavy the oem ones are?? The 4 I have all come in at 175g, which quality control can't be that bad! Ok 1 is 0.1g lighter and 1 is 0.2g heavier!
I all most went for these cause of the colour http://napolperformance.com/04-11-mazda ... e-set.html
So lots of coil manufacturers that seem to know a thing or two sticking to std shape ! Now would we call them fake as they look like the original? It's seems if it's cheaper it's not good, which tends to be the case the majority of the time! If other manufacturers make what's the original manufacturer makes, but at a cheaper cost is this always bad?

Re: Coils
They are smart and look bloody well made!
Looks like those i have are missing something and will probably stay on the fish tank!
Now and I know I write badly, but that's me so sadly can't change that! Would it not be a good idea to try and get our hands on some of these other coils and do a group test?

Re: Coils
At nearly 15 years on the market, I think if there were a cheap coil (and trust me, many cheap coils have been purchased in that time) that performed well, then I would have thought that they'd be the talk of the town.
Or are we assuming we've just been sat here arguing about oil all this time and not tried to saved each other tens of thousands of collective pounds :/

Now lets not get the oil thing going please!
To be honest ive now clue what everyones been doing over the last 15yrs as I'm new here and that might be the problem as I'm asking crap that was asked a long time ago! A bit like a driver sitting behind a learner.

Re: Coils
Well that has me convinced. You should buy some immediately and upload your pics of them fitted here. Increased HP and reduced fuel consumption? Makes perfect sense.
Maybe set up a group buy?!!!!
(I'd love to see the customs charge on those)

Re: Coils
Naw to be honest Ive got a set coils, but hey has anyone tried them????? If not its not a bit rude to say there sh*t and like he said theyve been on the go for 15yrs ok 9yrs for him!
Hey if I had the money I'd buy them to see for myself, but i haven't

Re: Coils
Ref oem coils jdm monitoring.
When i installed the bridgeport engine i bought rev C coils and after the rewire and on firing up i had no rpm displayed on my digidash.
I thought i had a bad connection but continuity test good. Basically taking a feed from the positive coil trigger to the digi dash...
Much head scratching i put the original NGK coil inplace of the rev c on the 1 with the feed to digidash and works.
Well this is simple wiring a positive trigger to fire the coil...but on the gen mazda 1s something is happening to trigger voltage.
I have too run 3 rev cs and 1 ngk on front trailering...theres summit in the oem coils....

Re: Coils
Apparently it’s easy to spot, but you must have genuine coils to deconstruct, which is more difficult to get than most would think! I think my B Rev coils in my car are genuine, so I’m going to take the worst one apart when I get around to replace them! I’ve ripped several apart and found nothing! My old track coach is a clever old git and knowns lots about sparky things, but shares nothing if it gets a bite!

Re: Coils
Hi Pete,PeteH wrote: ↑Wed Nov 28, 2018 2:04 pmI find this interesting. I can understand why JDM cars would be able to detect coil failure or swapped coils, because the Japanese regulations are so tight with regards to modifications, MOTs (whatever they are called), and emmisions. What I don't understand is, having gone to all the trouble of programming the PCM to do this, why then create a second programme specifically not to do this?
Did they really give the rest of the World the chance to mess about with coils just... because...? The consequence of that decision is so many misfiring destroyed engines. . The second consequence is that Mazda have missed out on thousands of replacement coil sales, because we all buy non-Mazda. Or were Mazda worried about the RX-8 getting a reputation for throwing CELs every 30k miles, so they just disabled the warning?
Do JDM cars have a better reliability record due to their owners getting a CEL every few years to tell them their coils need changing?
The whole thing makes little sense to me.
All vehicle manufacturers build their vehicles specific to each market.
It’s normal practice.
I worked for Jaguar Land Rover for a short period.
You have European market, Asia Pacific, North America, South America, Middle East, China, etc
Fact is it’s all down to local government emission requirements, safety requirements, road tax system requirements, consumer demands in the area.
For instance - all cars built for China have very little emission restriction measures compared to a UK spec car. And likewise a North American spec vehicle will have tighter emissions than a UK vehicle.
The cost to make a vehicle produce lower emissions is always going to be an additional cost.
So why produce these more costly spec cars for a market that does not require it? Save money building = lower price to the consumer or higher profit for the manufacturer.
Each market consumer also has its own cultural consumer needs. What Japanese consumers want on a car is very different to what we want in the UK. And what we want in the UK is very different to what they want in South Africa or North America.
So it’s down to local Market government regs relating to emissions, safety etc and the. Market research to consumer requirements regarding trim spec or performance etc.
So the basic conclusions is Yes manufacturers really do build vehicle to varying specification for different areas of the world.
They spend where they have to and where they can cut back costs - they do.
The emissions regulations at the time for RX8 in Japan May have been very stringent and so the engine management system had to be robust at notifying the owner as soon as there was a fault occurring.
In the UK at the time of production we were not so fussy. So if you are build tens of thousands of vehicles and you have an opportunity to save a few pence - (or the equivalent in Yen), then dropping spec for builds outside of Japan, - will save you tens of thousands maybe millions - depending on your total end output.
I have seen this happen with the Jaguar X Type. Jaguar deleted the, engine bay engine insulation,and a carpet trim in the trunk in a cost cutting exercise to try and redeem profit loss.
