That is very odd, the check is in place and is right AFAIK https://github.com/noisymime/speeduino/blob/master/speeduino/idle.ino#L719 Also, don't use 0 as minimum steps as it will definitely stall the engine, try something...

Currently you can only use one at time, both uses the same code internally, I made a PR(#845) to solve this, hope @noisymime analyse it for next release.

Are you using alpha-N fuelling?

I asked because is already based on load look here https://github.com/noisymime/speeduino/blob/94e90c5f637e4aabfdb9b61a4dff4b0a9fd4e3c7/speeduino/corrections.ino#L622

Ok, what you described is very different from your initial text, can you rename the issue to "O2 closed loop MAP threshold" to be clear the intent of the request?

Currently the secondary injection aren't limited at all. Usually the secondary injection have bigger injectors, that is why no limit is in place.

You can't just apply a limit for the injectors duty, if you do, you will have a lean mixture. The correct path is to enable fuel/ignition cut (like Rev limit)...

2% is effectively locking the correction, the correction resolution is 1% integer

That is doable but have some caveats, only the injection can be used in that mode and above a certain RPM as the compressions oscillations can cause a false trigger.

Clearly you haven't seen a cranking toothlog of a 60-2 wheel. The timing is inconsistent on cranking, yeah, the reference need to be done just once, but neet to be...
