It works no differently on DI than anything else...you aren't running anywhere near high enough static CR to predet (without knowing how aggressive timing is, kinda hard to really get into details) 93-120 octane fuel (pump/meth) Direct injection gives a higher fuel delivery granularity, and as a byproduct a higher static CR and lean condition can be achieved.... but all the rest of the monitoring and correction systems are there. If knock is detected, timing is pulled, just like anything else (actually, at a much faster sample rate since DI has awesome monitoring capabilities).

Don't overthink the system If you need current examples, check w/ the VW guys. The LS/LT 3.6L DI camaros already have wet nitrous kits available (50-100hp) from ZEX.
