Vehicle Compatibility and Return Conditions.

This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.

Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.

Ignition Controller, GM EZ-LS, Wiring Harness, Chevy, Small Block LS, Kit

FAST GM EZ-LS ignition controller kits deliver low cost and proven ignition control for any LS engine swap utilizing a variety of FAST EFI setups. They work perfectly with FAST fuel control systems, including EZ-EFI 2.0, XFI, and XFI Sportsman. The kits employ a simplified plug-and-play wiring harness and a compact, waterproof ECU enclosure--which makes clean, professional installation a snap. In addition, they are engineered to use stock LS crank and cam sensors to save money and installation time. Four LED lights indicate that the controller is powered up and receiving signals. These kits are designed to be extremely user-friendly by offering a quick setup option that doesn't require tuning or a laptop. However, for those that desire greater tuning control, the units can be custom-tuned via the EZ-EFI 2.0 hand-held (when hooked up to an EZ-EFI 2.0 ECU) or XFI C-Com software connected to an XFI system. The kits adapt to 1997-current GM coil-near-plug ignition systems and both 24x/58x tooth reluctor wheels. They're not compatible with LS truck-finned coils.
