2020 Gen IV 6.0L VORTEC ECM Programming deletions I recently purchased a Salvage yard low miles (30K) 6.0L Gen IV Vortec Engine gleaned from a 2020 GMC Savanna 2500 Van. I have what seems like the entire original engine wiring harness and an ECM. I want to delete or turn off the Vehicle Anti-Theft System (VATS), EGR programming, and the Variable Valve Timing (VVT). I don't have the vehicle key either. I tried a local dyno tuner I used for my carbureted engine in San Diego County and they didn't have the interface wires for my new ECM to their computer. Some of the Gearhead Geezers I know suggest getting an aftermarket engine wiring harness and controller from Holley, FITECH.... Any suggestions on how or where get my OEM ECM modified? I'm new to this and learning as I go. Thanks for any suggestions and or pointers. R/ Cyclefrog

jetech,
Thanks for the link and welcoming me to the LS Forum. I'm going to dig in get my two brain cells engaged. I will look up some other local tuners and see if they can assist.. Cheers, Matt
