CM2200 fuel flow limiter?

[ddart69340]

I’m having an issue getting desired rail pressure, and I’m tracing it back to a fuel flow limit, but I can’t find what’s limiting it. I can get mm3 and injection duration where I want it, and it’s commanding the RP I want, but actual RP is lower under high loads. The lowest I can get the FPR current is .70 amps, even though I’m allowing it to zero out if needed. Is there a table I don’t have access to, or am I missing something simple?

So your actual rail pressure is lower than desired? Sure you don’t have a mechanical issue? Cross tubes?

There are some pressure gain tables that are not available in the efilive software that you need to adjust to get pressure where you want it. Your pressure problem usually shows up with fueling upgrades.

You would need to have them CAX into the software.
