  1. Flashing over existing EFI Live tune

    EFI Live
    I just recently had some work done to my LLY. It has regular ol EFI live with a DSP5 from Kory Willis. I’m looking to change up my tunes. Unfortunately the tunes were uploaded via laptop and my tuner doesn’t have my stock tune on file. I’m looking to upgrade to an autocal, that way I always have...

  3. Used EFI Live Autocal

    EFI Live
    Hello all, I am currently going through my garage in preparation for a move and I stumbled upon my Autocal from Longhorn Fab Shop. Some time ago I sold the truck which the scanner and tunes were meant for so I am unsure what the value of it is or if it has any value at all. I have the cables to...

  7. Order to do mods?

    EFI Live
    I am fairly new to the Duramax world, but have quite a few hours of reading on here. From my research on here it appears that the V2 is for data logging and retrieving the stock programming for use by a tuner. So, I'm thinking that I need to purchase EFI live first and use the V2 to upload my...
  8. A question for tuners ???

    EFI Live
    I see a lot of guys making 50hp tow tunes, 80 hp tow tunes, 150hp race tunes and so on, so how do you know the HP for the tune when you create it? Is it just based on what you know a truck with similar modifications has will do or is there something in EFI that tell you this? Thanks Matt
  9. How does EFI and tow/haul interact?

    EFI Live
    I was wondering what effect EFI tunign has on the tow/haul transmission mode and how it all interacts with say a turbo brake EFI tow tune? Also, does the EFI tow tunes with turbo brake change the shift points of the tow/haul transmission mode? I have used my truck to tow a 6k camper and put it...

    Sort of a long story I will try to keep it simple. 02 LB7 just got out of warranty. Decided to pick up a used Hypertech programmer because it was really cheap. Turned out the VIN was locked. Talked to a few guys and they said that I could have the dealer cheat it by flashing my ecm with the...
