will set the default value if value is outside the min and max limits. tableLimits (optional) = intentifier, min, max, defaultVal Here is the section of the ms2ReferenceTables.ini file that controls that: IAT min = -40, max=350 if outside that range it goes to 70 CLT min = -40, max=350 if outside that range it goes to 180 CLT with EXTENDED_CLT_TEMP min = -40, max=400 if outside that range it goes to 350 default Currently only the CLT sensor respects EXPANDED_CLT_TEMP, the IAT does not. You can adjust these limits if EXPANDED_CLT_TEMP is set. This isn't a big deal in TunerStudio though, you can change these limits in the ms2ReferenceTables.ini file. The thinking is that if you are at an extreme it is probably a bad or missing sensor, so it goes to a default value. However, note that the tuning software limits the temperature range. However, you have to calibrate the thermistor table(s) appropriately. Then the upper temperature limit should be 600 degrees F.

air cooled engines with a CHT), in MS-II you can set the #unset EXPANDED_CLT_TEMP by changing: Since the CTS input is used for warmup enrichment, you want something that responds fairly rapidly, so this is highly engine-dependent.įor high temperature applications (i.e. A lot depends on whether the motor is substantially oil cooled or not. There are various arguments for and against using either CHT or oil temperature as the 'coolant' temperature input on air cooled motors. To use a MegaSquirt® controller with an air cooled engine, you will have to decide where the best place is for the coolant sensor: in the oil, or on the cylinder head (CHT). Here is the section in the manual that discusses the Expanded Temps

I have them set for Megatune but Tuner studio instructions are not working.

I've installed and got the engine to run and idle pretty well but I still can not find how to set the expanded temps ranges for Tuner Studio.
