    Andy, what's up?

    You can definitely do without a gauge. Now, some wideband units are integrated with the display. For example, my NGK AFX has a box which displays the AFR but is also required to...

    Joe,

    when I open up calibration 0202003 COS3 tune (which you do a full reflash with and then reflash the 1 bar tune on top of that) to get the full COS3 tune. There is no option to save the file...

    Looks like this software update caused nothing but trouble for me.

    It seems that a tune that was modified with the old software version cannot be modified with the new software version.

    Now, I...
  6. Updated EFI live software now can no longer modify tunes made prior to update

    I updated my software to V7.5.7. I have V1 hardware.

    I have been running a COS3 tune and now when I try and update injector data (went from 158 lb to 79 lb injectors) I save my changes and 2 files...

    You all are great. That did the trick. Mine is the old version, V1.

    I do get this warning when I open up tunes now though:

    Address Range Report
    The following calibrations have been excluded:

  8. Downloaded stock tunes from Tune File Depot are blank when opening

    I am able to download the files from Tune File Depot (i.e. 2002 silverado 4.8L tune) but when I open the file in EFI live, all data is blank. No tune is present. What's going on?
  9. It's DBC. In that case, are the drivers...

    It's DBC.

    In that case, are the drivers specific to the PCM itself, or is it just part of the tune? I'm sure there's a G-van 1mb tune out there available (they had cable TB to my knowledge).

    You might try looking for the injector data from a magnacharger radix truck tune.
  11. Thanks for the reply. At least know I know why...

    Thanks for the reply. At least know I know why there is no COS for that OS. I was always under the assumption it was just wasn't done and there was no care to do it, rather than an actual hard limit...
  12. Last ditch...ANY way to support flex fuel on 2002 COS

    I really want to run the ethanol sensor and have the PCM control fueling based on composition.

    I see posts here and there about people running hacked tunes to get this done and I am specifically...
  13. Thank you the responses. Makes good sense.

    Thank you the responses. Makes good sense.
  14. Values in tune being changed after saving and reopening tune

    Just wondering if anyone else has seen this issue. It's a COS3 tune on 2002 OS. I'm inputting the new injector values, save the tune, reopen and the values have been automatically changed. I.e.,...

    Cold start AFR is less than 6, that's all the gauge will read down to, maybe I can reconfigure it

    Stoich is 9.765 for true E85. But the stuff in the pump right now is winter blend, E70. So stoich is probably closer to 10.2. I don't see that making the difference here. 2 cranks tells me it needs...

    Any update on this? I'm having this same issue. Perfect starts on gasoline, but cold starts on E85 takes 2 cranks and sometimes it struggles to idle for a couple seconds after startup.
