No dyno, no tuner, no factory re-flashed ECU! The FiTech 70051 Ultimate LS Standalone EFI ECU kit is the ultimate LS swap computer for DIY enthusiasts who want full control over their engine and transmission. 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. It 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, wideband O2 sensors and a handheld tuner. FiTech 70051 also includes a feature to control GM electronically controlled automatic transmissions. This allows you to configure shift points, shift firmness, when to downshift, among other features. Compatible GM transmissions include the 4L60E, 4L65E, 4L80E, and 4L85E. Other LS engine-only ECUs are avaialble in the FiTech Ultimate LS Series if you're using a different transmission.
Kit comes with one 02 sensor. If you'd like to run a second, you may want to source a Bosch 17014 from your local auto parts store.

Q & A
Now that Project Chevelle is making some real power, we've decided to ditch the old tank, lines, and pump in favor of a new tank and pump from Tanks Inc.
In this episode, Project Chevelle takes a big step in its muscle car transformation. It's out with the little old 307 and to the dyno with our new 383 from BluePrint Engines!
Speedway Motors employee Pat O. is back to talk about a cool little nostalgic piece now available at Speedway Motors, our Fiberglass Tunnel Ram Shark Scoop.
