Sequential ignition/injector phasing

I am running a V1 on my 2003 Evo 8. The car has 4 AEM smart coils that are fired directly from the AEM sequentially using coil outputs 1-4.

The car has a misifire and sounds like a subaru. I have verified all four coils are activated and firing. Since setting up the ignition, we have not been able to get it to run properly. The coils are ran to the correct cylinders (ie, coil output 1 > cylinder 1)

My previous tuner was unable to get it figured out. I believe the coil and or injector phasing may be off.

Any help would be appreciated. I would be happy to email someone his .cal to look into it.

Here's the phasing now. It doesn't seem like its right.

I was able to figure it out, but unfortunately I have a bad coil driver in my Ecu.

Sadly the coil driver's have never been all that great in the AEM's. Had I seen this prior, that's the first thing I would have said. Glad you got it sorted, sucks on the driver though. Are there anymore in the box? You could just swap the wire or move the internal jumper and then alter the settings to accomodate.
