| ATV / UTV TFI Controllers |
|
Dobeck Performance has an electronic fuel injection controller for some of the first EFI ATVs and UTVs. The real technology behind the TFI is that it functions like a carburetor. It takes the knowledge and experience that many of us have and converts it to a fuel injection interface. The TFI interface makes it easy to tune for different modifications. The TFI is to be used on EFI ATVS and UTVs that have performance enhancements that require more fuel to run correctly, such as pipes, heads, even big bore kits. With patented ST technology this box does not default computers or trip engine lights. The TFI uses load based technology to monitor the demand on your motor and provide a fuel solution to reach optimum performance. This unit plugs directly in your factory wiring harness for easy installation.
TFI Key benefits include:
- Allows addition of fuel required with engine modifications without upsetting stock fuel map.
- Integrated dials provide easy adjustment and fine-tuning of fuel delivery curve without external programming devices.
- LED lights indicate fuel delivery settings while tuning.
- Won't interfere with ATV's/UTV's stock sensors and inputs.
