    I have a lq4 6.0 in a 2003 GMC sierra. will just the ECU alone work with the ls3 crate or would i need the full harness kit?

    Can we tune this ecu and if so what software package will tune this?

    Asked by: Dick 123
    These kits can be tuned, but are made to work well out of the box for most applications. There is a video about the ECU on this page - https://www.jegs.com/p/Chevrolet-Performance/Chevrolet-Performance-LS3-LS376-430-Engine-Controller-Kit/2375875/10002/-1
