Paul,
 Tracy does specifically match his ECU with specific coils.
 Neil.


 Too bad I'll have to get a new set of RX8 coils and put them
 on the test stand. If you have a set could you give me
 the part number printed on the side of the coil and what
 year you bought them?.

 I want to find out if I have the old or the new RX8 coils.

 Paul,

 I have a set of coils that came with my 2005 renesis engine that I
 did not use.  I am using the Denso coils that I had with the 13b.

 Check the bottom of the RX8 coils. If they look like this they
 have already been overheated and probably will fail shortly.
 When I took this off my car about an hour ago I freaked out.
 My 2004 RX8 only has 30,000 miles. According to the Internet
 I just dodged the new engine bullet.

 All you people out there with early RX8 car's change out the coils
 for the later versions. Mixing oil with the fuel will only help.
 It will not fix the problem.

 If you are flying with early RX8 coils watch out.

 Rino are you using the RX8 crank angle sensor and trigger wheel with
 the Denso coils?

 The part number on the coil from my RX8 is;
 N341 18 100
 A10-1355
 3627

 The last number appears to be the serial number
 as it is the only number different than the coils on
 the test stand engine.

 I have a new set ordered from Pep Boys so we will see
 what is different.

My coils number:

N3H1 18 100
AIC-1355
4609

No discoloration on the bottom of the coils that I can see.
It is from a 2005 RX8 with 500 miles on it.

Rino

The 500 miles could be the reason. It seems to happen around 30,000
miles. Also that serial number (4609)  may indicate they could be
the second gen versions. I'll know more when the new ones
come in and I get the part numbers off them.

Do you happen to know what dwell time Tracy is using for the
RX8 coils?

The only thing I can recommend for no spark is go back and check the
wiring.  I had to rewire the total system for my Subie, all 131 wire
ends (including monitor).  I labeled and diagrammed each plug and then
matched wire color and in some cases gauge to keep thing sorted.  Was I
ever surprised when it started the first time!  I will definitely be
using the simple ignition and mechanical FI on the single rotor  :)
