Hey everybody so I have a 82 RX7 with an S5 13B. Been having some trouble with the ignition though. I've been searching the internet like crazy, found a few threads that almost had the same issue but they were either a faulty igniter or pin 31 wasn't grounded.

So here's my issue:

I'm running FC coils with an FD igniter.
I have spark on Trailing 2, that's it.
I followed Nyt's instructions on wiring the igniter:

PIN 1 - Trailing Wolf (T1)
PIN 2 - To Trailing Coil (T1)
PIN 3 - Trailing Wolf (T2)
PIN 4 - 12V IN (switched)
PIN 5 - To Trailing Coil (T2)
PIN 6 - Leading Wolf
PIN 7 - To Leading Coil
PIN 8 - Unused (bridged to pin 7 inside the igniter)

Igniter is getting 12v (seperate relay/switch), same with each of the coils (also seperate relay/switch).

Igniter is definitely grounded well, same with the ECU. Have a bunch of extra grounds I added while doing this swap.

Pin 22 (Oxy sensor ground) Pin 31 (ignition ground), pin 35 and 36 (Ecu grounds) are all grounded, just to clarify.

I just got an igniter and pigtail off Japan2LA, thinking the one I had was toast, and still only sparking on trailing 2.

I then put Pin 5 from the igniter to each of the other coils seperate times, when I do this they each have spark, so I'm guessing the coils are good, I even have an extra set of coils that I swapped in and no change.

After (and this is quite hard to explain), thinking the igniter may be faulty, I changed Pin 3 and 5 from the igniter (the channel that was sparking) to each pin 1 and 2 and pins 6 and 7 seperate times. When I did this I had spark on the coils. So when the ECU is grounding out properly each of the channels on the igniter are working properly, this all makes sense to me...or am I doing this wrong somehow?

If anybody needs any pics or even a video of something to help out, please let me know, I will put it up ASAP.

Driveshaft was just finished, so after I resolve this issue car will be driving finally! Any help is so much appreciated. Also, I recently was able to get the ECU to connect to my laptop, noticed when I was cranking it a couple times in the program, it had multiple signal errors (bottom right box). How do I view these errors?

Wow really nobody can help me out?

s1rx

was this engine setup running with the wolf before the mods to the ignition system were done?

Yes this setup was running before I bought it. The guy had an issue with the battery being located in the back of the car (was gettin some sort of interference) but always started when it was at the front of the car. I asked him and he said e definitely had spark at all 4 since that was the first thing he checked. Now I'm not so sure though..
