Over Boost protection and Rev Limier

Over Boost and Rev Limiter.

Over Boost Protection

Over Boost will save you from dangerously unwanted boost level.

Under boost control settings you can set the Overboost Protection.
You can choose between Spark or fuel cut, or both.
Then you set the max boost - in kpa - 200kpa = 14.5psi = 1bar of boost.
Hysteresis is the kpa level below max boost where spark/fuel are re-enabled.

Set it right, it's important, especially when playing with boost controllers, actuators springs or other boost altering devices.


Rev Limiter

We all know what a rev limiter is, but here you can set a "smart" rev limiter.
I use "CLT based" rev limiter in order to limit rev on high\low CLT.

Lets go through the options:

HARD REV LIMIT:
Hard rev limit(RPM): RPM limit - 7200rpm for a stock internals miata - same as stock ECU.
Soft Limit Zone / Hysteresis(RPM): RPM needs to drop by this much from max RPM before fuel is re-enabled.

COOLANT TEMP LIMITER
Rev Limiter CLT Based: You can choose between normal rev limiter - only max rpm, or you can choose CLT based, that will let you use rev limiter in a more creative way.
Rev Limit TPS Bypass(TPS %): At what TPS % the rev limiter settings are ignored.
I recommend setting it close to 100% in order to allow emergency WOT.
RPM When In TPS Bypass(RPM): The new rev limiter when in bypass TPS %.
I think 7200rpm is good here also.

For all the rest of the options, no extra info - read the tool tip.
