Setting Rev limiter?

[Brody]

If I'd want to set a 3400 rpm rev limiter on a duramax DSP5 tune, how would I do this? Or can I even do this?

The ECM should be doing that now (I am assuming you are looking at a Bosch LLY/LBZ ECM), notice how the Desired Torque at 3,550 RPM = 0, that means there will be no fuel up there. You could change the 3,400 RPM column to be all zero's as well to achieve the same thing.

Appreciate it!
