Additional failsafes that are missing #58

This ticket for listing any missing fail safe features we think we need. Just a list here, future tickets for figuring out how to implement them.

  1. linear soft limp mode enable. Motorcycles dont take well to very sudden changes.
  2. Low oil pressure at high rpm, dont just cut power, but slowly decrease it. Drift cars.

Both points were exactly why I was saying high powered stuff needs to go into a limp mode in a controlled fashion. Just switching off is a bad time in some circumstances.

OK, how to do it....

We need to look at power reduction strategies, closing the ETB and retarding ignition if possible before shutting the engine off

I think we can probably leverage other mechanisms to do this. We might be able to use the torque reduction request logic for gear shifts, maybe the knock retard logic and the etb limiter logic in combination to achieve this.

If an error sets the rev limiter lower over x number of cycles and the knock is set to trigger on each cycle it will retard and close ETB in a controlled fashion before the cut.
