@SebAvi Hi Seb. Thanks for applying your keen observation to my newest aircraft. I hope you don't mind if I reply in list form, since I've been receiving so much feedback lately.
There should be a substantial impact on cranking performance, as it uses the same code from the Dukes. The increased friction, oil viscosity, and battery internal resistance should all play a roll.
Engine performance should reflect the density altitude, but my sound designer and I have not made an attempt to capture a rough running engine during the warmup phase.
I've received a lot of notes about this. This is one of the few features which I haven't taken complete control away from the simulator yet in my aircraft. I'm looking for a safe solution that I can roll out across my fleet.
The easiest way to induce spark plug fouling is to leave the mixture at full rich at low RPM and low CHT. I have seen this effect many times in these aircraft, since I often have the simulator running in the background while I troubleshoot code.
Thanks again! All your suggestions always make my aircraft better, so I'm always happy to listen!
