Default Question - Base Duty Cycle - 04-04-2017, 02:56 AM

I've read quite a few posts regarding menu 12/duty cycle, and notice the values on the iso firmware thread mention settings from 2-3.5.

Whole reason I'm asking this is because I was flipping through the menus on the wheel yesterday and noticed my menu 12 is set to 0? Is it supposed to be that low?

To quote T from another thread:

So should I just leave it at 0 then? Thanks

Doesn't really matter for E series N55 ISO since the turbo builds 3-4psi with no duycycle at all.
