Engine modding

Engines.txt
This text file is used to control the settings of all the engines available in the game. You can change engine sound, power, raise or reduce RPM limit, set minimum and maximum RPM. You cannot add new engines.

File Contents
The file is made into sections and each section has the engine name as the section header that is written in square brackets.


The syntax is as follows:
[engine name]: The ‘type’ used in the car data file.
blockOBD: Determines whether OBD (On Board Diagnostics) is allowed with this engine.
engineSound: Sound of the engine in the game.
maxpower: The maximum power of the engine in stock non-tuned (parts and dyno) state.
maxPowerRPM: The engine RPM when engine produces the maximum power.
maxTorqueRPM: The engine RPM where the maximum turning power (torque) is made.
minRPM: Lowest RPM of the engine. This is the engine’s idle speed (for real world petrol engines)
maxRPM: This is the maximum RPM an engine will reach (the rev limiter). Combining maxRPM, finalDriveRatio value and size of the wheel gives the maximum speed. This is calculated by assuming that you have the needed power to get up there.

Example:
[kaszlak_engine]
blockOBD=True
engineSound=maluch
maxPower=230
maxPowerRPM=4800
maxTorqueRPM=3400
minRPM=1000
maxRPM=6500

This represents the Maluch RWD I4 (inline 4 cylinders) engine.

Kaszlak engine from the games files.


Note: In the game, the engines are handled as a single unit. This unit will have a gearbox and two exhaust parts (down pipes and header). Because of this, some engines cannot be swapped.

For example, in the definition of turbo I4, 4WD or RWD gearboxes are not included. So cars using I4 configuration cannot use FWD I4 engines. The driveshaft and exhausts will not connect up and the cars will point in the wrong direction.

Modding
Modding can be easily done either using a text editor or the Car Mechanic Simulator 2015 Mod Manager (created by Blue Icarian Wings).
