Requires: max allowed pressure reduction by ETB, toggle option for etb, toggle option for wastegate, maybe a max pwm duty cycle increase for wastegate.
Should remain on until driver lifts throttle to prevent surging. Should be the next action after the enrichment if knock still present.
4. Use water meth.
In cases where vehicle has water meth injection then this should be activated in addition to the initial spark retard.
In a siuation where EGT results are available and the engine is near EGT limit then this should take preference to retarding spark.
I.e. above user defined EGT spark max retard is reduced to user defined level and meth is activated as soon as knock is detected.
Requires: flag "has water meth", user defined EGT limit, maybe water meth pin assignment, user defined water meth pwm? Trigger water meth from gpio table?
EML severity: no action until the need to reduce boost, at which point flash light.
### Overboost protection.
This one is more easy, take similar action to knock stages 3 and 4.
EML severity: Solid on for light as boost reduction will take care of it, if after x cycles boost still high then flash light.
### High coolant temperature.
Intended to help prevent mishaps with overstretched cooling systems.
Use knock stage 2 and 3, if 4 available then activating has benefit to reduce in cylinder temps.
If EWP then also demand increased or MAX pump duty cycle for x time (1 min).
If electric fan then enable fan until temp is restored.
Requires: user defined maximum coolant temperature, boost cut and enrichment optional.
EML severity: solid on for light while temp is over set limit.
### High EGT.
Where vehicle has EGT sensing allow user to set a preffered EGT limit and max exceed value.
If EGT limit is reached light eml and enrich. If EGT max exceed value is breached flash EML.
