EXTRACTED AND REFORMATTED FROM THE SIMCODER’S WEBSITE: https://www.simcoders.com/2018/02/16/rep-3-3-new-big-bore-engine-model/
A new update of the Reality Expansion Pack for X-Plane has been released with new features and improvements, especially to the engine.
This update is free for all the current REP users. If you don’t have a copy of it already, you can get it from the store.
New 100% custom engine model
A new piston engine algorithm for big bores such the IO-520 and the IO-550 that will greatly improve your experience.
X-Plane 11.02 introduced a bug that, in some occasions, prevented REP to set the proper engine power output. This bug was the cause of errors in cruise speeds, fuel flows, CHT, oil temperatures and, generally speaking, engine dynamics.
Luckily, Laminar provided a new way to override the engine model with XP11.10. Seizing the opportunity to rewrite our code to make it better than before.
The engine code does not depend anymore on Laminar’s piston engine model of X-Plane. That is, it is a fully custom engine model that do not rely on internal X-Plane dynamics.
Therefore, all the algorithms in the big bore engines are custom. They provide great precision in EGT curves, fuel flows, CHTs and – more important – power output!
