I've seen this question thrown around a lot lately. From the post I made in the 370ZTT Thread:

We had great success working with the COBB AP (and COBB directly) with this 370ZTT. With the MAFS, the car drives flawlessly. The cobb software can drop the timing curve, but the ECU has a lot of logic that modifies the curve to be what is optimal for the car at any give time.
So timing changes must be well matched - say if the curve that you've put in is too aggressive, at points the ECU may adjust. We tested the COBB AP extensively with the 370Ztt and experienced no knock, no limp modes, no codes (HFCs work wonders) and the car simply runs perfect (and moves out!)

I am not sure about the G37 however as it is different and we have not yet (but soon) tuned a twin turbo g37 with the COBB. The only way we could control the G37 required hard-wiring f-cons in the past.
