BTW how many people on here are planning on using RX8 coils?

   I might be prematurely worried.

  Hi Paul

  I am planning at this stage to use the RX8 coils that I have.

  Can you read the part numbers on the side of them. It is usually
  very faint so you might need bright sunlight.

  BTW please call Ian and give him a heads up. I think he is
  using the early RX8 coils in his rotary powered RV6 as well.
  He may have one or more bad coils and not know about it.

 He had some failures with his RX* coils. This was attributed to Tracy's EC2
 having the wrong dwell setting. He now runs another aftermarket ECU (can't
 remember which) and non RX8 coils.
 Me thinks, but could be wrong.

 I'll check my coils when I get home from the office.

 Great info Steve. The plot thickens :)
 As I recall Ian is now using a HalTech. I think HalTech is
 an Aussi company. The dwell can be set on a HalTech.

My RX8 coils are marked (checked two of them):

N3H1  18  100
   AIC - 1355
       3111

Obsolete part. Likely to fail.
The latest Mazda part number is N3H1-18-100B-9U

Plan on getting new ones when you are ready to run.
We are working on a heat sink also to make them
less likely to over heat. I'll keep every body informed
on that.

Also I think the after market BWD E1001 seems to work.
That is probably sold world wide. A lot cheaper than
the Mazda part.

If they are used coils you should check them with this procedure:
ignition coil test.pdf. One or more may have already failed.

If you are good at electronics you can build this tester.
Just make sure you have a foot of spark plug wire
coming out of the tower with a plug on the end. Don't try to
spark anywhere near the coil as it will re trigger and kill itself.
