EZ-EFI Fuel Touchscreen Hand-Held

The EZ-EFI Fuel Touchscreen Hand-Held Programmer is a 3.5-inch touch screen fuel injection control system designed for universal retrofit and aftermarket fuel system applications on gasoline-powered vehicles. This programmable controller serves as a replacement option for builders and enthusiasts who need flexible fuel management without factory ECU limitations, making it suitable for street rods, classic car restorations, engine swaps, and custom performance builds where aftermarket fuel delivery calibration is essential.

The 3.5-inch touch screen interface provides intuitive access to fuel mapping, sensor configuration, and real-time diagnostics. Weighing 1.87 lbs and measuring 6.4 × 2.7 × 12 inches, the hand-held unit is compact enough for mobile tuning sessions or shop use. The touch-based programming approach reduces the learning curve compared to button-based legacy systems, allowing technicians and engine builders to adjust fuel curves, idle quality, acceleration enrichment, and sensor thresholds with precision. Universal compatibility across a wide range of engine platforms makes this programmer a flexible solution for diverse build scenarios where standardized fuel system control is required.

This unit targets engine builders, restoration shops, and performance enthusiasts who require aftermarket fuel system management independent of OEM electronics. Whether tuning a carbureted-to-EFI conversion, optimizing a turbocharged engine platform, or fine-tuning a naturally aspirated swap, the hand-held programmer offers direct control over fuel delivery parameters. The replacement designation indicates it serves as an alternative to proprietary or discontinued fuel management systems, providing buyers with a contemporary retrofit option that combines modern interface technology with universal vehicle application capability.
