I had the 1.17 loaded up until last night when I returned everything back to stock. Then I hooked the livewire back up to my computer and upgraded the firmware on it and loaded the 1.20. Then today while driving to work with the dpf still on I got my CEL. So after work I grabbed the DPF delete pipe along with the rest of my exhaust and headed to my buddies house where we installed it. I drove home with the CEL still on and then I tried flashing it again but yet it still has the CEL with the same codes as before. So now I'm just confused. Could I have a faulty livewire?
