Nice to know someone who is using MS2 V3 on a 1NZ-FE.
I just did one to my customer's Yaris. Running wasted spark setup.
Here's what I did:
Combine the signal wire of the COPS as 2 pairs.
* IGT1 + IGT4 --> Ignition Output from your Channel A 5V PNP mod
* IGT2 + IGT3 --> Ignition Output from your Channel B 5V PNP mod
Make sure you change the ignition setting to "Wasted Spark", "Going Low" in TunerStudio
Hope it helps.

It's a square wave back to the factory ecu when the ignitor in the stock coil works.
If it is not present the stock ecu will shut down the injectors to prevent flooding the catalyst with fuel.
For a MS application you should be able to just not use those signals.
Or you may be able tie the IGF terminals from all the coils together and use that signal for a tachometer
