Frequently Asked Questions About the Focus ZX3 ID1750-XDS

What is the approximate maximum horsepower limit the ID1750-XDS supports on a boosted Focus ZX3 4-cylinder?

The ID1750-XDS can support well over 500 wheel horsepower (whp) on a highly tuned 4-cylinder Ford Focus running E85. This is the top-tier injector for extreme turbo conversions on both Zetec and Duratec engines.

How does the provided characterization data help my tuner map the idle speed control (ISC) for a smooth Focus idle?

The precise dead time and flow data allows the tuner to accurately calculate fuel delivery at the smallest pulse widths. This is essential for controlling the Idle Speed Compensation (ISC) valve, ensuring a stable, non-stumbling idle despite the large injector size.

Are these ID1750-XDS injectors the correct physical size (full or short) for the Focus ZX3 fuel rail?

This specific ID1750-XDS unit (Part No. 1750.60.14.14.4) is supplied with the correct full-length body required for a sealed, direct-fit installation into the factory or common aftermarket fuel rails used on the 4-cylinder Focus.

What effect does running the ID1750-XDS have on the factory fuel pressure regulator (FPR) of the Focus ZX3?

Due to the massive flow rate, the factory FPR will almost certainly be overwhelmed, leading to inconsistent pressure. An upgraded, adjustable fuel pressure regulator is required to accurately meter fuel return and maintain stable pressure.

Is the high-impedance design of the ID1750-XDS a direct electrical match for the Focus's factory ECU?

Yes, the ID1750-XDS is a high-impedance injector, which means it is electrically compatible with the stock Focus ECU's driver circuits. This simplifies installation by eliminating the need for bulky external resistor packs.
