ECOTRON EFI KIT 28MM

Our Small Engine EFI Conversion kit also supports a Turbo charger. Compared to our NA (natural-aspirated) version, this kit just needs to change to a 2.5bar MAP sensor and a bigger injector. Same as the NA kit, it has some self-tuning capability by running close-loop fuel with an O2 sensor. Our ECU has sophisticated self-learning software which can automatically tune itself to run in stoicometric AFR (14.7) in variant operating conditions. And this kit can be used to convert single cylinder small engines with 50cc to 300cc range displacements.
This kit previously is called "PNP" kit. But because different people have different understanding of "PNP". We now removed the "PNP" in the title. As much as we try to make this kit as a bolt-on kit for some popular small engines, like GY6 engines (50cc to 200cc), and 150cc monkey bikes, this kit requires some efforts to be installed correctly. PNP may not apply to every engine, simply because of so many different engines out there. PNP may only apply to certain GY6 engines, or 150cc monkey-bike engines. If you have modified your engine a lot (w/ major customer parts), it may not be applicable as PNP. In many cases, the user will need to do some basic tuning after correct installations. Please contact us to confirm whether this kit can be PNP to your engine.

• High fuel efficiency and low carbon emissions
• Decel-fuel-cut-off
• On board self-diagnosis with a MIL lamp
• Performance tuning for advanced users
• On-the-fly calibration
