    Fan Hub variances

    The LBZ fan clutch is shorter than an LLY's, but not much, and then you have to use the larger fan.

    2002 a/c et al

    AC Delco can be good stuff, but many of there older compressors(like the H6 that haven't been used for almost 20 years), they are outsourcing, and buying from 4 seasons. In my experience, 4 seasons has been a 50/50 crap shoot. GPD is an overseas company, but they are mostly Taiwan & Korea, not...

    anyway to unlock efi live tune

    For future reference, this doesn't work for LB7's, it's a different pin you have to ground to force the unlock(I don't recall which one, but somebody figured it out a few months back on the ls droid fb page).

    LB7 drop in stock appearing turbos

    It's a Precision ML 1800 stall.

    High engine temps

    I bought one of Kennedy's fan clutches a few years back and was surprised to see it was a Hayden/Imperial manufactured fan clutch, but it did have a different calibration spring, and the shaft was clocked different than a stock Hayden. So far it has been good, but I put ZERO faith in Hayden's...

    LB7 drop in stock appearing turbos

    The turbo in my BURB is getting pretty loose on me with 278k miles, so I'm looking for a replacement. The Burb is pretty much only used as a backup/workhorse now with diesel prices what they are, and I prefer to drive my 2 door 2WD Tahoe if given a choice. The only mods are a set of 45 over SAC...

    GDP EFI LIVE

    Because of all the companies closing up shop because of the EPA, EFILIVE now offers an unlinking service for $50 I believe. But that still leaves youc looking for a tuner. I know I stopped about 8 years ago when I seen the writing on the wall. And to the OP, your 07.5 tune cannot work in your...

    EFILIVE June 2019 public release downloads?

    Dave hit the nail right on the head. I have to update to at least this version to add new VIN licenses, but I know some functionality was said to have been removed with the later versions. I hadn't saved any newer versions since 2017 because efilive said they would never require us to ever...

    EFILIVE June 2019 public release downloads?

    If you can get it worked out, that would be great. I saved the V8, so that can come down. I used to have a dropbox, but it stopped working awhile back, should probably try it again, and see if it's working or if I have to open a new one.

    EFILIVE June 2019 public release downloads?

    Does anybody out there have the June, 2019 public release versions saved that could send them to me? It's the oldest version required to get new VIN licenses activated. V8 Software: V8.2.24 V7.5 Software: V7.5.28

    P0089 and Cp3 humming

    There is no solution to this, they all do it if you check them. It's the ECM modulating the FCA.

    04’ Lb7 smokes a lot at idle

    Since you say your balance rates were all 0, most likely your injectors are done. Balance rates zero out when your fuel rate drops to low and the ecm sees 0 or less fuel being injected into a cylinder. Balance rates are how far +/- each injector is injecting from the main fuel rate. Say you have...

    LMM AC compressor adapter?

    03+ diesels use 2 individual hoses, not a single manifold. Google "denso 10s20f adapter" and they will come up. Or you can go to the 01-02 ht6 compressor which will bolt in place of your compressor, and accept the manifold you have pictured.

    Another '03 LB7

    You can always go with the SAC00's.

    Will LML Allison work on LBZ???

    Not to mention the valve bodies are different. 01-10 had a basic set pressure regulator setup, 11+ gives the TCM control over line pressure. And the extension housing uses a completely different transfer case bolt pattern.

    LB7 stand alone harness questions

    Alldata gets there diagrams straight out of the GM service manuals and have found virtually no differences between alldata and my GM disc.

    LB7 stand alone harness questions

    01 LB7 ECM's are different from 02-04. 01 doesn't have the circuit to read oil pressure iirc, no egr ability, and had some internal differences as well as operating system differences(hence why if you flash an 01 ecm to an 02 OS and then back to an 01, it permanently corrupts the change engine...

    02 lb7 into 01 burban 2500

    The 2500 Sub is like the 1500hd/2500 pickup as far as frame and body height. You either need a 2" body lift or the staggered lift blocks to fit the Duramax core support into a 2500 Suburban. You will use the Duramax engine/trans harness but use the Suburban body and other harnesses. You have to...

    Time for injectors stock or 30 overs?

    The cel wasn't on, just no fuel gauge, or dual tank system.

    Time for injectors stock or 30 overs?

    Yup, they now check the checksums. They have been checking the OS numbers for years which is why trucks with a dsp5 would fail as it changed the OS#, but they stepped it up this year. It has caused issues with swapped trucks as the tune file present must exactly match the truck your swap came...
