BHR Ignition Kit Doesn't Work!!

This is why I am pretty sure that both the AP and the ProTuner are both not TRULY measuring dwell in MS - since the factory map is way above 5ms.
Since we know the factory ignition is about 3-3.8ms; I just modifyed it by 130-150% and smoothed it some. It works great on PunisherRX8's car.

I had always thought the factory dwell map was reading like this 595 = 5.95ms ....

1) The int-x setting for the factory ignition = 3.0 to 3.8 ms dwell.
2) Jeff scoped the PCM and saw a 3ms signal.
3) 3 - The PCM Troubleshooting manual has some information about the ignition characteristics which seem to indicate the 3-4 ish MS Dwell Times since the entire ignition sequence takes just under 5ms including discharge at idle.
Then look over at the PCM info - and at full voltage at idle we see 1200-1100 ish... so IMO is is a scalar of some kind.

$5 on Flashwing!
any man who can drink BEER like him, surely can throw down.

WTF?!
First Brice calls me a douche bag now you calll me an idiot.
Well, at least it proves I'm an equal opportunity hater.

haha, but then I'd have to ban myself when I pick on the stupid.

I've been reading through these threads regarding the use of LS2 coils since my girlfriend just bought an 05 RX-8 and the start-up has been very sluggish.
I own an 05 GTO, and I have to say that the GM coils are extremely efficient coils. There are plenty of high horsepower LS motors running 600+ horsepower to the rear wheels on the stock ignition system. The MSDs don't provide much more than added bling under the hood.
Save your money and go with the stock LS2 coils. They are very good coils, and will hold up to whatever you throw at them.

Fundamental misunderstanding in how the dwell table works here.
Fundamental misunderstanding in how the coils fire.
Fundamental misunderstanding in what the Yukon coils "need" for dwell time.
There is so much FUBAR info in this thread I can't even look at it without my head hurting, hence my post here.
Try actually scoping the output before you make such drastic assumptions about how all of this works.
Also, do the math on what the dwell "requirements" are. Don't forget to include what the spark voltage requirement is to jump the gap under operating conditions. You will see why there is no need to concern yourself with dwell settings in an NA application and why it only matters at 300g/sec + from 4200 RPM until 6800 RPM.

Look -
A whole bunch of crap has been pushed out onto this board about how this thing works and when it doesn't.
Much of this is based on a fundamental misunderstanding of what the BHR kit is supposed to do and how.
As designed (and for the application for which it was designed), it works exactly as advertised.
If you lack the proper tools to modify the system and the tuning to suit a purpose beyond that which the system was designed to address, than you are **** out of luck.

I should add - that I set the Dwell to 5ms on the Int-X and the coils work like a raped ape!!!
So they work!!! But if my dwell table (3D Flash Style) is wrong then help a PAYING customer out here... I don't need my ****** car tuned; I need a dwell map for the ignition I paid for. And I sure as hell don't need to be told I am stupid - I know I am stupid!!! That is why I pay smarter people to design products for my car.
Diversification of labor is a win-win for everybody.
