May have to compromise a bit in the smoothness but it definitely is the lesser of the two evils... at these power levels too.
Yeh have been doing a bit of reading about JB4 "PI safety" and its still not a full proof solution for people running PI. There is no individual injector control and only has the ability to shut-off PI buy monitoring things like throttle position, gear etc. In a WOT situation if there is DI shutdown by the DME, PI will continue flow (until you let off the peddle) but all this will be happenning in milliseconds so the JB4 solution will not be able to respond in time. It all comes down to the auxiliary controller having no communication with the DME
