Thanks for the help man, I was hoping someone else had the same problem before.
reset your eshaft sensor also..

After reading Jeff’s (mazdamaniac) posts in the Corvette LS1 Ignition Coil Project https://www.rx8club.com/series-i-aftermarket-performance-modifications-23/corvette-ls1-ignition-coil-project-137423/ I decided to pursue the same concept but instead of using GM LS2 coils I went with MSDs 8247.

http://www.msdignition.com/pdf/8247.pdf

Take a look at this website for more information regarding the LS1 and LS2 coils.

http://www.megamanual.com/seq/coils.htm
I read the entire thread and atachments, thanks for the zip, very interested thread although this project was done over a year now and possibly there have been many progress of the options to set this custom kit, my questions and concern is that your car is Supercharged others are Turbo.

This can be a noob question but is it possible to set the LS2 Coils with a NA RX8, keeping the original ECU. Or will I need a upgraded ECM. I'm planning to buy the Cobb but I want to avoid having it remapped after the LS2 coils are installed.

Right now I've asked pricing for the BHR Ignition Kit but as well will like to install the Cobb after upgrading the iginition.

Any help is appreciated. Thanks

By using the proper coil terminal on the plug wires like BHR does with our Ignition System. Chickenwafer has a set of terminals waiting for him at my place should he decide to make the 40-minute drive.

1) Thanks to MM's wiring harness, which has a patent-pending, it is and it requires NO dwell adjustments to the PCM.
2) You did? I didn't get a PM. The shipped price for the BHR Ignition System is $485 and it has a better warranty than you might expect. The Cobb and BHR kit work quite well together.

Just for clarity, I don't think he's implying that you would need to make dwell adjustments to the PCM for the LS2 coils if you don't use MM's wiring harness.

I was trying to be very clear. You know how often people around here make their own inferences.

Hey Charles, so your saying that the MM harness is only built in the BHR kit and it's not available separately like Fluid MotorSports is selling theirs ?

Has anyone compared the quality of these 2 harness ?

No doubt the BHR kit is awesome, but has anyone done this research ?

I don't seek to jack this thread any more than Juan has been kind enough to alllow but I would like to only add this;

The wires and construction practices of harnesses are but a minor part of the entire equation. Second-handers will never have the intimate knowledge necessary to assist those who have questions after they buy something, unlike those who actually conceived the idea in the first place. This is something to consider when buying anything. Would one feel more secure buying an actual HKS blow-off valve or a knock-off found on E-Bay? Since they did not put in the research time like BHR did, I am fairly confident that problems will result along a multitude of issues and we have darned-good reasons for doing things as we have.

What is even worse is that BHR is soon to offer the harnesses and plug wires separately and they will cost less than others out there already. They will also carry my usual unbeatable warranty. Even custom lengths for remote coil locations. I am already providing them to people............

The Harness is available through Fluid Motorsports.

Rote8 has the Harnesses we made, I would ask him if he is satisfied.

You have the original, BHR. Designed harnes(patent pending),,,,
And you have a copy cat version. Fluid Motorsports.

Who do you think designed the system in the first place? And who do you think came along for the ride on the short bus.

Okay, now that Brice has appropriately chimed-in can we give Juan back his thread?

Come on man, that's unnecessary, and is a wiring harness really that complicated? If you want to debate the novelty and non-obviousness of this wiring harness then feel free to PM me, it doesn't belong here. Also, what's wrong with some competition?

I have yet to buy anything from Brice, but when the time comes I will weigh my options like I (and most people) do with everyone. So far Charles is in the lead with at least a (well spent) grand in purchases.

I'm making the order this week. Thanks OD.

And what's with all the BS about harnesses? No one cares, did everyone think there was only gonna be one harness design out there? That's the way business goes...

Stay tuned for more BHR product like a shifter gate, then. I least I will be able to explain how it works better than Brice can.
Hey, maybe I will ape Mazmart's water pump design and find out where they get their thermostats from, too. Would that be acceptable to you guys?
If we gotta eat, we might as well start with each other, right?

If you can offer these things at a better price, then go for it! That's what capitalism is all about. With the customer base you already have, I'm sure you would have no problems selling these things.

I don't care for shady & underhanded people just like the next man but as long as the business is legit & follwed by good & moral practices then personally I see no problem. I love competition & choices, it develops the market & engages the mind for new ideas.

The cheapskate option would be to buy a burnt out set of coils from someone here and make connectors out of them and tag on the D581 harness. Thats what I did...someone else did it before me though. Its plug and play. Then you can make your own mount for the coils. Took me a day to put it all together. I figure it would take anyone else with tools to do it in the same amount of time.

yea i made mine too--but it took a little time to gather the stuff and then making a mount etc was a little work--most people like plug and play. options are great to have. Business in America is very competitive.
