Stop conversion-related jerking at the right source.
On the listed engine families, jerking after CNG conversion can occur when the required MIJO Optimiser has not been installed. The correct application-matched version helps remove those jerks and restore smoother drivability.
Why the optimiser is used
A missing application-specific part can leave the driver with unresolved jerks.
Some supported engines need an optimiser as part of the CNG conversion. If it is left out, the conversion may run but the vehicle can continue to jerk on gas. The MIJO Optimiser range gives vehicle owners and installers a clear, engine-matched solution for these applications.
Jerking can also have other installation or calibration causes. The complete CNG system should be checked by a professional before the optimiser is selected.
- 01Confirm when the jerking occurs
Tell the installer whether the symptom appears during CNG operation and under which driving conditions.
- 02Identify the exact engine
Vehicle make, model, cylinder count and engine capacity determine the optimiser version.
- 03Check whether the required optimiser is present
For a listed application, an omitted optimiser may be the missing part behind the CNG jerking.
- 04Fit, verify and road-test
The matched unit must be installed professionally and the complete conversion checked afterwards.
Two application-specific versions
Choose by engine—not by appearance.
Both optimiser units must be matched to the supported vehicle and engine family. Their similar role does not make the two versions interchangeable.
Maruti 1.2 L · Kia / Hyundai 1.2 L
01 · Version 1
MIJO Optimiser
Maruti 1.2 L · Kia / Hyundai 1.2 L
Version 1 is the application-matched optimiser for supported Maruti four-cylinder 1.2-litre engines and Kia or Hyundai 1.2-litre engines.
Where the required optimiser has been omitted from the CNG conversion, the vehicle can continue to jerk during gas operation. Installing the correct unit as part of a professionally checked conversion helps remove that conversion-related jerking and restore smoother drivability.

Common questions
What vehicle owners should know.
The optimiser is application-specific and should be considered as part of a complete professional diagnosis of the CNG conversion.
Does every CNG vehicle need an optimiser?
No. The optimiser is used for specific supported engine applications where this correction is required. MIJO or an authorised installer should confirm the exact vehicle and engine before supply.
My vehicle jerks on CNG. Does that prove the optimiser is missing?
Not by itself. On the listed applications, an omitted optimiser can be the cause, but the installer should also check the complete installation, calibration and connected components.
Which optimiser version is correct for my vehicle?
Version 1 covers supported Maruti four-cylinder 1.2-litre and Kia or Hyundai 1.2-litre engines. Version 2 covers the three-cylinder Swift and Maruti 1.5-litre engines. Final compatibility must be confirmed from the exact vehicle.
Can the optimiser be installed after the CNG conversion?
Yes, when the vehicle is a supported application and the correct version is confirmed. A professional installer should fit it, check the complete system and verify the result on the road.
Next step
Is your converted vehicle jerking on CNG?
Share the vehicle make, model, year, cylinder count, engine capacity and existing CNG system details so MIJO can confirm the correct optimiser route.
