I dont see much wrong.  Below is your BREBET4 log with the wasted spark log overlaid on top (pink traces).  In the wasted spark run you are commanding about 6deg more advance and about 10% less fuel so thats going to make it run noticeably different.  

I dont see any obvious signs of trigger error but you would need to get an oscilloscope on it to confirm arming threshold.  Sometimes with piggyback installs the trigger filtering in the OEM ecu can mess with the trigger voltage at high RPM so it would be worth getting a scope on it if you dont find anything else.
