Return PolicyNo dyno, no tuner, no factory re-flashed ECU! The FiTech 70050 Ultimate LS Standalone EFI ECU kit is the ultimate LS swap computer for DIY enthusiasts who want full control over their engine management. Avoid having to buy additional software programs, learning how to think in computer code, or relying on a questionable 3rd party tuner. The included color touch screen interface allows for custom tuning adjustments to your LS engine as well as a self-learning program to get you on the road. FiTech Ultimate LS EFI is the perfect product for using the factory GM intake, throttle body, and injectors, while leaving the factory GM computer and harness in the junkyard where they belong. FiTech technology is custom cam friendly and is suitable for use with most 4.8 LS, 5.3 LS, LS1/LS6, 6.0 LS, 6.2 LS, and LS7 GM engines.
Kit includes LS engine wiring harness, standalone LS ECU, one wideband O2 sensor and a handheld tuner. The FiTech 70050 is an engine-only ECU, however other FiTech Ultimate LS EFI ECU kits are available to control both engines and electronic transmissions.

Customers appreciate this product for its easy installation and convenient operation. The product is highly compatible, with the majority often just needing to plug and go, simplifying the install process. It is equipped with both EV1 and EV6 injector harnesses and new coil harnesses too, offering comprehensive coverage. Users also appreciate the product’s flexibility, citing the ability to use any type of fuel with the right injectors. It pairs well with the msd 2 step controller, and the touchscreen functionality allows for additional tuning capabilities. Some customers mention it does not support timing reduction for nitrous but can support up to 30lbs of boost. While it does require some additional purchases like an adaptor for the 3-bar LS3 map sensor, it is considered a worthy investment overall, shown by the customer's successful use in daily driver swaps and drag racing. Despite some reports of missing connectors, overall satisfaction with the product's quality and ease of use is reported.

Install was simple. Just plug and go on 99% of the kit. Other connections are simple..... Supply 12 volts , a good ground, and power wire to your fuel pump. Under initial setup on the touchscreen, enter what you got. Mine fired up first try. It takes a few minutes of idle to smooth out while it's learning. Would work well for a daily driver swap, or in my case a drag car. I used 100lb injectors, and can run any fuel I want. It does require a 3 bar ls3 map sensor, but you have the option of buying an adapter to run your stock sensor. This kit does not come with transmission harness but can be added later. Only comes with a single o2 sensor, but has a plug available for a second. Also comes with both ev1 and ev6 injector harnesses. It also includes new coil harnesses for both sides. Currently, this kit does not support timing reduction for nitrous, but will support up to 30lbs of boost. It does work with the msd 2 step controller, and will also let you connect a laptop to it and tune beyond the touchscreens ability.
