New to the Duramax but not to EFI LIVE Help
Ok. Got a little problem. I bought a 2009 lmm with 83k miles on it a couple weeks ago. I'm trying to install EFI live on it from Ridge Runner, and getting code error 0537 which is locked ECM. I talked to the previous owner before I bought the truck and specifically asked him if it ever had a tune on it. He told me no. All the EGR, Cat and DPF was still on the truck. I removed the DPF and Cat yesterday. I can here the EGR turning off and on so I know it's not shut off. My truck is my daily driver so I really don't wanna send the ECM in to get it unlocked, but looking like I might have to. Any suggestions?? Thanks
PS the autocal did read and save the tune that was on the truck.
