The Atiker Microfast OBD2 LPG conversion kit is a popular choice for car owners looking to switch to LPG for fuel efficiency. However, like any automotive system, it can experience issues. Many users, especially those new to LPG conversions, may encounter problems after installation. One common concern revolves around initial setup and adjustments to ensure smooth operation, particularly right after the conversion and during colder engine starts. Let’s delve into some typical problems and how to address them.
One frequently reported issue, mirroring concerns raised in online forums, is rough idling or stalling when the engine is cold, especially immediately after switching to LPG. Users describe scenarios where the engine struggles to maintain a stable idle, sometimes even stalling, until the engine warms up. This can be accompanied by poor throttle response during the initial cold start phase. These symptoms often point to incorrect settings within the Atiker Microfast OBD2 system, particularly related to fuel mixture and pressure at lower temperatures.

Diagnosing these cold start and idling problems often involves checking several parameters. LPG injection times, gas pressure, and nozzle sizing are critical factors. If the LPG injection duration is excessively long at idle, or if the gas pressure is not correctly calibrated, it can lead to an overly rich mixture, causing rough running. Similarly, if the nozzles are not appropriately sized for the engine’s requirements, it can disrupt the fuel delivery and air-fuel ratio. It’s not uncommon for initial installations to require fine-tuning of these settings to match the specific vehicle and engine characteristics.
If you’re experiencing these issues, the first step is often to consult with the installer. A competent LPG technician should be able to diagnose and rectify these problems by adjusting the Atiker Microfast OBD2 system parameters using diagnostic software. They will typically check the injector calibration, gas pressure regulator settings, and ensure the system is correctly reading OBD2 data for optimal fuel trim adjustments. However, if you are not comfortable returning to the original installer, or if you suspect a lack of expertise, seeking a second opinion from a reputable LPG specialist is advisable. For technically inclined users, with appropriate knowledge and equipment, some basic adjustments might be attempted, but caution is advised as incorrect modifications can lead to further complications or even damage.
In conclusion, while Atiker Microfast OBD2 systems offer a reliable path to LPG conversion, addressing issues like cold start roughness often involves careful diagnosis and adjustment of system parameters. Whether it’s fine-tuning the injection settings, checking gas pressure, or ensuring correct nozzle sizing, a systematic approach is key to resolving these problems and ensuring smooth and efficient LPG operation. If in doubt, professional assistance from an experienced LPG technician is always the recommended route to ensure your system operates optimally and reliably.
