• OBD adaptation is suspended at extreme LTFT values (from OBD) (i.e., -100% or +99.2%). This prevents erroneous fuel enrichment in cases where the LTFT value is -100% during OL, and the loop status read from the OBD changes to OL with a delay (up to 2 seconds).
• aux12V in the fuel pump control function—when the polarity was set to 0V, a 12V output was present after the ignition was turned off, unnecessarily powering the connected device. Now, this voltage is always reset to zero after the ignition is turned off (regardless of the set polarity).

• An occasional gas pressure error that occurred when using the KME Gold regulator has been fixed (the error occurred only when manually switching from gasoline to gas)

• For engines with unit injectors, the option to select fuel pressure emulation has been disabled

• The measurement of the digital accelerator pedal position signal has been corrected,

• Fixed the map "collapse" (it was collapsing in the wrong place)
• In vehicles where turning off the ignition cut power to the controller, the following information was not saved to non-volatile memory:
  • The maximum exhaust gas temperature, which can be updated automatically while driving on diesel
  • The maximum value of the knock sensor, which may update automatically while driving on diesel
• In some cases, the maximum exhaust temperature and knock value were not updated in the app (though the controller was updating these values correctly internally)
• The issue of an exhaust gas temperature error occurring after turning the ignition key has been resolved
• The delay in starting the exhaust gas temperature measurement that occurred after a controller reset has been eliminated
• In vehicles where turning off the ignition cuts power to the controller, clearing errors via the app may not have worked (they reappeared after resetting the controller)
• If a knock sensor error was logged, the car would switch to gas only after the ignition was turned off or after manually switching it via the control unit (this issue was particularly noticeable in cars with a start-stop system)
• no knock sensor was detected
• The default minimum gas pressure has been changed from 60 kPa to 30 kPa
• The default labels for the rows and columns of the throttle map have been changed (after a factory reset and after auto-calibration)
• Adjustments to the flow of gas injectors have been added
• Added support for the CNG-AC-12V pressure gauge
• We have added detection of gas pressure sensor measurement range overrun and programmed a response to this
• Added a "engine warm-up" message when the reducer temperature has not yet reached 50°C during autocalibration
• Added automatic clearing of current errors before starting autocalibration (previously, if there were errors in the list, autocalibration would be immediately interrupted)
• During autocalibration, knock detection is disabled (it is activated only after the knock sensor has been calibrated)
• The maximum allowed RPM for the autocalibration process has been increased (from 1,000 to 1,800)
• After auto-calibration, the default settings will be restored:
  • injector flow correction map
  • temperature correction map
  • throttle map
  • Accelerator pedal emulation map
  • minimum gas pressure

• Added the ability to emulate the accelerator pedal position
• Added the ability to adjust the injection timing of the gas sequence (requires configuration of the crankshaft speed reading).
• Added digital recorder functionality (ability to monitor RPM, diesel injection, and gas injection in real time)
• A cycle counter for gas injectors has been added
• Added support for gas injectors:
  • Dymco Black
  • AC W01 BFC
  • AC W02 BFC
  • AC W03
  • Lovato JLP04
  • AEB I-Plus (aluminum trim)
  • AEB I-Plus (plastic strip)
• We have added the option to select which errors will trigger a continuous audible alarm. Additionally, you can configure the system so that the audible alarm also sounds during operation without gas injection.
• Added the ability to instantly adjust the gas flow rate (when switching modes and while running on gas)
• Added a visualization of the moment the error was detected (a vertical red line on the oscilloscope in the diagnostic application)
• Fixed the shaft speed reading when the number of pulses per revolution is greater than 63
• the gas temperature correction has been reduced
• The pressure/throttle pedal emulation has been modified and now depends on the ratio of the current to the target throttle position.
• The flickering of windows in the application has been eliminated, for example, during the automatic setting of the maximum exhaust gas temperature or maximum knock.
• A defect causing an incorrect interior temperature reading when the ignition is turned on has been fixed
• The "no lambda sensor" error will not cause the system to enter "Failure" mode
• The default settings have been modified:
  • Max. exhaust gas temperature reduced from 690°C to 300°C
  • active "max. auto exhaust temp."
  • Max. voltage drop from 2V to 0.8V
  • active "max. auto ignition"
  • "threshold" from 5V to 1V
  • "injection type" from "sequence" to "standard"
• The "Max. Exhaust Temp." and "Max. Knock" settings, along with their "AUTO" checkboxes, will revert to their default values after successful autocalibration

• Pressure emulation has been accelerated (the Check Engine light caused by emulation should disappear in most cases; in the remaining cases, its frequency will decrease significantly)
• Fixed an issue where, under certain conditions, gas was not injected when the crankshaft was rotating
• Fuel pressure emulation on/off functionality has been fixed—the issue affected certain vehicles, where the relay activation caused the engine RPM to fluctuate or even caused the engine to stall.
• Fixed monitoring of power supply voltage drops (the "low power supply voltage" error should no longer appear during voltage spikes)

• Added the option to select the type of pressure reducer temperature sensor
• RPM measurement has been improved (in some vehicles, such as 4-cylinder engines with five crankshaft pulses per revolution, the measurement was inaccurate and unstable)
• false voltage error detections in peripherals have been eliminated
• The "Injection measurement threshold" setting has been hidden.

• New "Engine Type" setting.
• New settings that allow you to adjust the speed at which the system switches between fuels.
• Two new algorithms that assist in estimating the maximum exhaust gas temperature and the maximum knock voltage—the controller automatically monitors these parameters and updates the settings.

• The system for tracking working hours on gas has been updated, while maintaining the previous standard for calculating time until the next inspection.

• Automatic gas level adjustment feature.
• New list of gas injectors.
• Improved support for two knock sensors.
• Improved support for vehicles with mechanical fuel injection.
• A new setting that determines the number of knock sensors connected.
• A new setting that determines the rate of change in gas flow.
• A new setting that saves the minimum accelerator pedal position.
• New setting for adjusting the acceleration-based fuel cut-off function.
• The ability to automatically change the load axis on the map.

• Adding auto-adaptation to the KWZ map
• The variator detects unsupported waveforms and displays a message during autocalibration
• New error codes (ignition switch missing, unstable ignition switch signal, detection of signal interference from the crankshaft position sensor)

• Accelerate synchronization with signals from the camshaft position sensors.

• Accelerated synchronization with signals from the camshaft position sensors

• Added support for OBD frames
