Good stuff, dude.
Nice to see someone else having success with the LS2 coil system.
As Juan said, it works. I've had over a thousand miles on my system and it performs flawlessly.
It is a significant upgrade - you can easily feel the difference in drivability and power, especially over 5000 RPM.
Actually, that is already in the works. We should have an announcement in just a few weeks.

Logged 50+ miles today at all kinds of speeds, acceleration, meth on/off, AC on/off, you name it.
Here are the results:
4 MSD 8247 from eBay....................$245.00
4 D581 Connectors...........................$ 26.68
Assortment of hardware from HD........$ 7.58
Strong yet smooth acceleration........Priceless
I'm doing an AutoX tomorrow and will be able to put the coils to the test. The AutoX event is an hour from my place and I will be driving at interstate speed 70+ for at least 45 minutes each way. I think that will definitely test and prove that the coils work.

I was asked: “How hard it is to fab and install? Would it be an easy fit where stock coils are?"
I’m afraid you will have to wait for someone to try to put the MSDs in the same location as the OEM coils. I think it will be a bit challenging because the MSD coils are much beefier than the OEM.
Not that hard if you go with the GM LS2 coils. You will need to get custom made connectors. Basically you will need to connect the OEM coil connectors to one end of the custom coil connectors and the other end to the GM LS2 coils plus a ground wire from the modify connector to the body.
Check with MazdaManiac, BHR or TeamRX8 regarding the modified connector. They commented earlier about manufacturing for later sale.
See below pictures of MazdaManiac’s GM LS2 coils.

I was asked: “could you tell me where each specific wire goes, pics would be great too”
If you would like to go my route and splice into each OEM coil wire connectors like I did then here is how it is done.
Each OEM coil connector has three wires:
The black with a white stripe B/W is your positive 12V wire.
The solid black B is your PCM ground.
The (each OEM connector coil trigger wire has a different color) green G (Leading 1), white W (Trailing 1), yellow/green Y/G (Leading 2) and blue L/D (Trailing 2) are you coil trigger wires.
Just make sure that the D581 plug that you are using for the MSD coils matches the MSD coil pin order to the OEM wire. See diagram below. The same goes if you are going to use the GM LS2 coils without a (future) modified connector.
Note: The fourth MSD/GM LS2 coil pin is where the extra ground (anywhere in the chassis) go.

Uuuhm, sorry sir. I artifically inflatuated my post count just so you would think I has some cred. Pardon me. 
<- right back at ya!
Now, let me get on with the FGS I am working on. I really need to turn my emails off when I'm in the zone. Some poor bugger will end up using Pro Tuner and getting a message box popup and say, "Oh boy, here we go again..." in reference to some forum argy bargy. LOL!
Cheers,
Hymee.

I'm worried that one of the MSD's will fire any second now and blow us all up with all this methane hanging around from all the inflatulance...
There - that was my feeble attempt to humorously get the thread back on topic.
Cheers,
Hymee. Now keep coding, son!

Well folks back from an awesome AutoX event and my feedback. Driving to the event location was 78 miles at mostly steady highway speeds, no AC because it was 40 degrees. I was able to run four laps (meth ON of course) with every lap better than the previous lap because the temps finally got to @ 65 by the end of the fourth heat and the tires go better grip (that goes to most of the people that participated in the event). Coming back from the event was the same but with the AC on.
So here it goes………….everything smooth as silk plus my miles per gallon increased by @ 4.5 miles.
I’m extremely happy with the MSD coils upgrade, period.
