Staging mode
Turbo Mini Forums

The current version of the code has the option of using injector staging but only with respect to RPM. Do you think it would be better to also have the options to stage relative to intake manifold pressure or relative to TPS. For a turbo engine I can see that MAP would be a good indicator of injector pulse width and therefore the need for the secondary injector but TPS would not be as useful a triggering method.

Let me know if you think that RPM is not sufficient for staging injectors and if so what would be best.

Keep it simple Jean!

I'd say RPM switched is fine...

RPM will probably be sufficient, but from what I"ve seen on turbo motors, high RPM isn't necessarily the worst place to run lean. The worst place is usually at peak boost, which is usually not at peak RPM. I've even seen fuel taper off at the top end to get a bit extra power.

I'm having trouble figuring this for our particular case tho, where injector size isn't the restriction, but valve timing is... so I don't know...
