    Lc is just low load conditions so I doubt I'll blow it by making minor adjustments. I'm only straying 10% of the Holden numbers so I'm sure it's ok, but I will be getting the wideband hooked up so...

    Well, I put the original parameters on the lean cruise tune and the mileage went up. Then I modified the lean cruise numbers slightly higher and I lost even more mileage. It seems leaner makes...

    That's what I feared. I made an attempt at that but gave up. Guess I'll have to try again....

    I have actually seen it drop slightly but I'm trying to get the original tune parameters put back on because it gets less with or without lean cruise on. Maybe the 00 tune is more conservative or...

    Are there any indicators in the tune that we can easily identify whether it's a DBC or DBW and 4l60 or 80? That way we can reference this in the future.

    OMG Man! That is awesome. Worked the first time, no changes needed! Thanks a million. I got the lean cruise enabled now so Ill let you guys know what kind of mileage I get for work tomorrow.

    Exactly right, so what do I need to do in the tune to change to DBC? Is it as easy as changing parameters or do I need to swap segments?

    2000 Yukon XL 4wd 5.3l automatic

    I want to upgrade the os so I can implement lc and other fuel saving methods in the pcm, which I believe is only possible on 2001 and newer versions. Thanks

    Could I use an express van tune then or how do I get a DBC tune?

    I agree, I won't try to set up lean cruise until I get this 02 tune running like it should be.

    Regarding the 02 tune, is there a different one that only runs DBC? It does seem like that's the...

    6125 is from an 02 Yukon so that's why I picked it. But it doesn't seem to like it. Is the wiring different or something? Is there a different os I can upgrade to in order to get lean cruise set up?

    Maybe this is the wrong section since no one has answered this seamingly simple question. Could someone move this to the correct section? I guess this section would be where I post my issues with...
  13. New to EFI Live, help with updating 2000 to 2002 os

    I am new to efi live but not HP tuners. My brother and I have both. I read through all the forums concerning the upgrade and when I upgraded my os last night, the reduced power light was on and it...
