Small Engine Fuel Injection Conversion Kit for Turbo
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 125cc to 600cc range displacements.
This EFI kit has below features:
Electronic fuel injection (EFI)
ECU controlled ignition system (via CDI)
Close-loop controls with an O2 sensor
Dual fuel maps selectable by a manual switch (Performance Switch: ECO vs. RICH Mode)
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
Parts:
1.ECU
2.Harness (including the connectors)
3.Throttle Body Assembly
28mm Throttle body (including TPS sensor)
or 34mm Throttle body (with a built-in idle motor, and TPS sensor)
Fuel injector (80/128/190/230g/min)(1.5 to 2 times of your NA injector size)
4.Fuel pump assembly
Fuel pump (compact size:38mm diameter) (comparative low power: 2A current) (Flow rate: 25L/h)
Fuel pressure regulator(3bar)
Fuel filter
fuel hoses and clamps
5.MAP sensor (2.5bar)
6.Engine temperature sensor
7.Intake air temperature sensor
8.CDI - for ECU controlled spark advance (INCLUDED, for better controls)
9.Oxygen sensor and bungs (INCLUDED)
10.Serial communication cable (to a computer)
11.USB adaptor (included, USB connectivity, and no need to convert to RS232)
12.CD - free tuning software (also downloadable)
Note: the turbo charger itself is NOT included.

This kit may require tuning for turbo applications. The tuning efforts are mainly in a few basic fuel / spark tables (via EcoCAL tuning software). All sensor characteristics and injector / ignition drivers we have taken care of, so to reduce the user's tuning efforts to the minimum.
This kit needs a 12V battery and charging system.
28mm Flange Throttle body doesn't have the injector seat. We will provide the injector seat separately in the kit. You need to welder it to the intake manifold. Please contact us for more information before purchasing.
