Power Fuel Stretcher ECU

Piggy-Back Fuel Injection & Pulse Width Stretching

The Power Fuel Stretcher is a precision piggyback electronic control unit designed to stretch fuel injection pulse width for extra horsepower and torque, while feeding a valid synthetic Oxygen (O2) signal back to the vehicle's factory ECU.

Tuning is performed through a intuitive "graphic equalizer" GUI. Fueling can be decreased by up to 50% or enriched up to 80% (typical performance gains require 5% to 15% enrichment).

Synthetic O2 Closed-Loop Protection & Boost Control

Our smart algorithm follows real O2 sensor signals during engine idle for consistent starting and smooth idling. During full-throttle enrichment, the Stretcher outputs a synthetic stoichiometric O2 voltage signal to prevent the factory ECU from trimming back fuel.
