CommandNumber of parameters

reset_ts0 Resets TunerStudio debugging counters


CommandNumber of parameters
caninfo0 Shows stats for CAN subsystem
enable can0 Enable CAN hardware. Also disable can
enable can_read0 Enable reading/sniffing CAN commands with echo. Also disable can_read

Knock Detection

CommandNumber of parameters

enable tpic_advanced_mode0Enables TPIC advanced (digital) mode
enable knockdebug0Verbose mode
hipinfo0Shows HIP9011 driver state
set_gain1Sets HIP gain parameter, betweb 0.1 and 2. New value would be applied on the fly
set_band1Sets HIP target frequency, in kHz. New value would be applied on the fly
set_hip_prescalerandsdo1Sets HIP prescaler and SDO. 0 for 4mHz, 6 for 8mHz


CommandNumber of ParametersDescription
chartsize1Sets the size of engine sniffing buffer in ECU. Nothing would change on your screen until a new larger packet of engine sniffing would arrive from ECU.
get date0 Gets current real time clock
set date XXX1XXX is time in seconds sins Unix epoch - see
echo1Just prints out the parameter - this is useful for troubleshooting connectivity
fatal0 This command would cause the firmware to halt. I am not sure that you want to try this one :)
fl1 'full logging', Turns-off constant dev console data output. fl 1 would turn it back on.
help0Prints the list of supported commands
hello0Prints the version of firmware
performance info0 Development:Software:performance#Event_handling
readconfig0 read config from flash/EEPROM
resetconfig0Resets configuration to default
set ignition_offset1
set cranking_rpm1 Sets the RPM level at which we consider the engine to be cranking - not running
rpm1 For example, rpm 1200 sets the RPM for built-in position sensor simulator
set engine_type1 This will change the configuration from the default Dodge Neon configuration.
You should reboot the firmware after changing engine type.
Hit the reset button or just power off/on the microcontroller.
set global_trigger_offset_angle1Change the offset between trigger sync point and TDC#1
showconfig0Shows current configuration stored in the flash memory - that's where you can see your current fuel map etc.
threadsinfo0 list of ChibiOS threads
umountsd0 Un-mount SD/MMC card
writeconfig0Write config to flash (you only need this if you have used one of the 'setXXX' commands) TODO: implement a feature of not actually writing changes into flash while engine is running since flash writes freeze the CPU. TunerStudio burn has this feature of delayed until engine is stopped burn already.
get_int, get_short, get_float1prints the configuration value at given offset
set_int, set_short, set_float2changes configuration value at given offset, for example set_float 102 1.23


CommandNumber of ParametersDescription
sdinfo0 Prints a report of SD/MMC usage
umountsd0 Un-mount SD card
enable sd/disable sd0


Trigger is the camshaft or/and crankshaft position sensor(s)

triggerinfo shows some info regarding trigger situation

set global_trigger_offset_angle XX

sets global trigger offset from synchronization point of trigger decoder to actual TDC #1

TODO? rename command? rename variable?

enable/disable trigger_only_front

In 'only front' mode, only signal rises are used for trigger decoding. For example, enable trigger_only_front

enable/disable trigger_details

Trigger details additional output helps with troubleshooting trigger synchronization issues.


Prints trigger shape definition


analoginfo0Shows ADC intut values
tempinfo0 prints out some debug information on CLT and IAT sensors
tpsinfo0 prints out some debug information on TPS sensor
mapinfo0 prints out some debug information on MAP sensor

Board Control

set_injection_pin: 2 parameters: index, PIN

For example, set_injection_pin 1 PB7

set_injection_pin_mode: 1 parameter

For example,

set_injection_pin_mode 1

Currently four modes are supported:

OM_DEFAULT = 0 (GND for logical OFF, VCC for logical ON) and OM_INVERTED = 1 (GND for logical ON, VCC for logical OFF)


set_ignition_pin_mode: 1 parameter

set_idle_pin_mode: 1 parameter

For example,

set_idle_pin_mode 1

set_fuel_pump_pin_mode: 1 parameters,

set_malfunction_indicator_pin_mode: 1 parameters,

Fuel Control

See also

set_whole_fuel_map: 1 parameter: global value for the whole fuel map, in ms

for example, set_whole_fuel_map 11

set_fuel_map: 3 parameters For example set_fuel_map 2200 4 15.66 Set 15.66ms value for 2200 rpm @ engine load 4

set_cranking_fuel: 1 parameters, for example

set_cranking_fuel 5

set_injection_offset: 1 parameter, for example
