PS 1000 trailing coil #1 misfire
I am having trouble with the firing of my trailing coil. I just went from a microtech to a haltech platinum sport 1000.
leading coils are working properly
trailing #2 working properly
trailing #1 is rarely firing and when it does, it is out of phase by aprox. 180 degrees
ignition output #1 is triggering leading coil for wasted spark
igntion output # 2 is outputting the phase for trailing spark
ignition output #3 is the deciding wire for which trailing coil to spark.
igniton output #2 and #3 have been checked where the harness connects to the coilpack and seem to be outputting the correct signals.
3 different coilpacks have been swapped in, all with the same result of trailing #2 misfiring/ not firing.
the haltech ecu was swapped into another rx7 that runs the same ecu and his maps were loaded in and the ecu worked fine in his car.
thanks in advance for any assistance.

ahh man.. this bad boy had me going for the longest time too.
Here is the correct wiring layout:
Leading Coil = Ign #1
Front Trailing = Ign #3
Rear Trailing = Ign #4
You don't use Ign #2 for waste spark configuration.

Well I have it right then because i have an FC. Ludwig I bought this haltech from you btw, do you think its the software in the unit or do you think its not wired properly? Is there anything else i can try?

You are probably correct when you say the problem resides in the installation... Ryan (my tuner the one whos installing this (Im just playing middle man lol)) took the harness out from under the dash and stretched it out long ways and the timing on that trailing moved like 20 degrees ???
Anyone have any idea what in the harness is causing this?
