Autogas conversion technology is evolving rapidly, especially for direct injection engines, GDI conversion to gas, and CNG/LPG retrofitting. Installers worldwide are increasingly comparing traditional European systems—such as Poland Europegas, STAG, KME, AEB, PRINS, and BRC—with new high-performance Chinese ECUs including LyanteGAS, China Delafegas, and China Europegas.

This guide explains—first from a technical standpoint, then from a commercial perspective—how to select a Chinese ECU that offers excellent performance, long-term stability, and strong value for professional autogas conversion workshops.

TECHNICAL SECTION

H2: 1. Core Technical Requirements for Modern Autogas ECUs

A high-quality ECU must be compatible with the latest engine technologies used in Asia and Europe. Key technical requirements include:

Compatibility with GDI, MPI, and turbocharged petrol engines
Advanced petrol emulation to prevent injector overheating
Intelligent correction algorithms (LTFT, STFT)
Precision control of gas injectors for CNG conversion kits and LPG conversion kits
Ability to maintain stable performance in variable temperatures and fuel quality

Chinese ECUs have significantly improved in these areas over the last five years.

H2: 2. GDI / Direct Injection: The Most Important Selection Criteria

H3: 2.1 Multi-Phase Injection Control

A good GDI ECU must support multi-phase petrol injection and synchronise gas injection timing to avoid power loss.

H3: 2.2 High-Pressure Pump Protection

Incorrect calibration may lead to excessive pump temperature. Quality ECUs—such as LyanteGAS and Delafegas—include dynamic pump protection similar to AEB and KME.

H3: 2.3 Real-Time Monitoring

Essential features include:

Real-time data logging
Petrol/Gas blending mode
Injector duty-cycle tracking
Safety fallback to petrol when required

H2: 3. MPI / Indirect Injection: Wide Compatibility

For inyección indirecta (MPI engines), the ECU should provide:

Stable switching between petrol and gas
Accurate MAP, temperature and pressure readings
Pre-configured maps for common Asian and European engines
Compatibility with various injectors and reducers

Most Chinese MPI ECUs today match the performance level of mid-range European brands.

H2: 4. Long-Term Calibration Stability

Professional installers focus heavily on stability, because fluctuating STFT/LTFT values cause:

Rough idle
OBD errors
Increased petrol consumption
Catalytic converter issues

Modern Chinese ECUs now utilise advanced feedback algorithms and high-precision sensors to maintain stable calibration under real-world driving conditions.

COMMERCIAL SECTION

H2: 5. Brand Comparison: China vs Europe

Below is a realistic market comparison based on installer feedback and large-volume fleet usage:

Brand	Country	Strengths	Market Position
LyanteGAS	China	GDI capability, stable software, OEM/ODM available	Growing rapidly
China Delafegas	China	Strong cost advantage, good MPI performance	Mid-range fleets
China Europegas	China	European logic + Chinese pricing	Entry & mid-range
Europegas Poland	Poland	Balanced performance, good software	European standard
STAG	Poland	Reliable, mature platform	Professional market
KME	Poland	Strong hardware quality	Mid/High tier
PRINS	Netherlands	Premium GDI technology	High-end only
BRC	Italy	Durable system for fleets	Trusted globally

Chinese brands—especially LyanteGAS—have become strong alternatives to European competitors for 2024–2025.

H2: 6. Why Chinese ECUs Provide Better Value

H3: Lower Cost, Higher ROI

For markets using GDI conversion kit, CNG conversion kit, or LPG conversion kit, Chinese systems offer:

40–60% lower cost
Faster delivery
OEM customisation (software + hardware)
Spare parts availability

H3: Suitable for Growing Markets

Chinese ECUs are widely used in:

Latin America
Eastern Europe
Southeast Asia
Middle East
Africa

due to strong balance between performance and price.

H2: 7. Supply Chain & After-Sales Advantages

A good Chinese ECU supplier provides:

Long-term component supply
Professional technical training
Remote calibration support
Flexible warranty terms
Stable production capacity

These commercial advantages are extremely important for workshops converting 50+ GDI vehicles per month.

H2: 8. Conclusion: Choosing the Best ECU for Autogas Conversion

Whether you are converting direct injection, MPI, CNG, or LPG, the ECU is the heart of the entire system.
Modern Chinese ECUs such as LyanteGAS and Delafegas now combine reliable performance with attractive pricing—making them a smart choice for workshops looking for stability, speed, and profitability.
