Direct Injection Cost and Ignition Timing

[nerd]

Adding systems that automatically adjust ignition timing and such are an interesting thought. For the most part I agree with the fuel choice comments too, apart from the choice of leaded vs. unleaded and the important effect of that on emissions / regulations / game progression in general.

Could you perhaps implement an option called "Engine Knock Protection"
Obviously it would make not much sense in Sandbox but could improve your image because a customer would not throw a fit because your engine does not run properly on 91 RON because it's designed to run on 95 RON.
To see an idea in sandbox, clicking "Engine Knock Protection" on an engine with an octane rating of say, 93.3, and then clicking 91 RON would detune the engine by way of compression until it is below or equal to 91.0.
Unclicking it would cause knocking on 91 RON.

You can't detune the compression on an engine though, so that doesn't really make sense.. (unless you're talking about the Saab variable compression engine which never went into production... but thats a whole other crazy thing)

This would make sense if you had some sort of ECU or engine management tech. Then it could detune the engine by way of retart ignition timing as real cars do when running on poor octane fuel.. Some cars such as the first gen MR2s had a switch that would adjust the timing based on fuel quality as well.

Maybe any engine that's designed to take a higher octane gas than regular should be more expensive (and less expensive as the years go by) to show that there is anti-knock protection? I don't think that something like anti-knock protection is worth taking up space.

never saw ron indication on a porsche 911 or a ferrari

It's in the owner's manual.

I would be surprised if there was a car without a fuel spec in the owner's manual.

There we go, Auto reduce Ignition timing is how modern anti-knock systems work, not Auto reduce compression.
