I've read over the manuals and can't find any information on this.
Does the fuel and timing curves set by the last two rpm breakpoints of the tables extrapolate on the same slope past the last rpm breakpoint? Same for the last two map breakpoints?

For instance, my redline is 7800 rpm and I want to make the last rpm breakpoint for my tables 5900 rpm. The breakpoint just before that is 5200 rpm. Will the curve or slope that is setup by the 5200 and 5900 breakpoints continue on the same slope past the last 5900 rpm breakpoint to infinite?

Also, if the line does continue on, will it still be restricted by the +50, -50 percent off of the setup UAP for that row? What I mean is, if this continuing line has an upward trend and reaches an rpm where it crosses above the +50% value for that row, will the line stop and flatten out at that +50% or will it cross the +50% limit for that row and continue on the same slope to infinite?

The values from the last RPM column will carry on at higher RPMs. Values from prior columns are not a factor.

In theory the RPM value you have set for the last column is beyond your peak HP RPM so fuel requirements per cylinder event should be the same or decreasing. If things are getting lean at those off scale RPMs it's likely you are hitting 100% duty cycle. Remember that as RPMs rise there is less time available for the injector to fuel the cylinder.

If your HP is rising after the last RPM column you will need more fuel and will have to rescale RPMs.

Thanks.
