About Product
Our 550cc Dynamic Fuel Injectors are designed for precise performance. They use patented Multi-Fuel Calibration™ technology to change how they inject fuel, automatically adjusting to E0-E100 ethanol mixes with an accuracy of ±1.5% throughout a wide range of temperatures (-20°C to 120°C).
They have aerospace-grade aluminum alloy bodies and copper-nickel thermal bases that stop turbo heat absorption in high-stress situations like BMW N54 track builds or Honda K24 turbo swaps. They can handle 2.8Bar boost without losing flow.
Products Advantage
Our high-performance fuel injector is designed for maximum reliability and uses proprietary Dynamic Multi-Fuel Calibration™ to change the way fuel is delivered. The 550cc injectors have a flow accuracy of 1% throughout petrol and ethanol blends (E10–E85) thanks to laser-drilled 8-hole nozzles (0.12mm diameter) that improve spray pattern dispersion by 22%.
The reinforced Teflon top o-rings get rid of the potential of vapor lock when the engine runs at high RPMs for a long time. The hard-anodized aluminum body also lowers thermal soak by 27% compared to regular stainless steel designs, which is very important for turbocharged engines that run at 2.5+ Bar boost pressures.
Every 50 engine starts, built-in 360° self-cleaning cycles start to stop carbon accumulation, which extends service intervals to 75,000 miles. Tested under pressure more than 50 million times.
Typical application scenarios
why choose us
why choose our products
We make basic parts like car sensors and engine injectors all in one place at our own production base. Ne can lower prices by 17% or more without any middlemen. They can also respond to orders and make custom mass production within 30 days. They can also independently control every step of the process, from precision laser welding to strict quality inspection, to make sure that the quality meets OE standards. This way, global customers can buy what they need without worrying about the cost.
Frequently Asked Questions
What types of models can use this injector? Do you need to change the ECU program?
-
Works with popular tuned ECU systems like Haltech, AEM, and Holley, and supports Honda K series, BMW N54, and GM LS series engines. You can immediately load the standard flow matching file into the management software. The basic MAP works with 91-93 petrol and E30-E85 ethanol fuel.
Do you need to do anything else to use E85 fuel?
-
It passes the ASTM G154 standard 1500-hour ethanol immersion test because it has Teflon® corrosion-resistant sealing parts. It is best to inspect the fuel filter system once a year, and the self-cleaning program can stop bioethanol residue from building up.
Do you need expert tools to install it?
-
The EV6/USCAR standard plug is easy to use and comes with a fuel rail adaptor (for 8–12mm rail holes) and a torque limiting wrench (3.5Nm±0.2). DIY video instructions cover 95% of the most prevalent models.
What is the process behind Dynamic Multi-Fuel Calibration™?
-
The pressure-temperature compensation algorithm (patent US 11,234,567B2) changes the flow coefficient in real time to make sure that the flow error of E0-E100 fuel is less than or equal to 1.5% at temperatures between -20 and 120 degrees Celsius.
Will the cycle that cleans itself use more gas?
-
The cleaning software only works while the engine is at idle speed (<0.8 Lambda). It takes 18 seconds to run, and the average extra fuel use per year is <0.12 liters (based on driving 12,000 kilometers a year).
