A little help with the engine testing diagram

I was hoping someone would be able to break down the various things displayed here.

I believe this is all accurate:

Directly from the engine designer manual:

What do I do if the throttle starts to go red, how do I fix that?

Good god. How on earth are you managing to do that? Maybe upload your .lua files here if it isn’t too much trouble, I’m curious now.

Rev between 6 and 7, near the wastegate light, and the throttle starts to go bad.

It goes away with the addition of a direct injection / throttle per cylinder config, but that was too expensive for the engine.

Possibly it means that there is not enough fuel being injected?

Doesnt say that in that alternate test. Tried everything up to 10:01 fuel ratio. still gets it.

The throttle turning red means that the engine wants to suck in more air than it can. It’s related to the power figure shown when you select the fuel system.

As per what Killrob said, alternatively, the turbo’s pretty large for the engine as it is. Shrinking the compressor also yields immediate results.

Awesome. Thanks for the help.

On an unrealted note. Killrob finally talked to me. I can die happy. lmao
