    Forum Server Move

    Not sure if it is related to the server move or not, but the ET Calculator doesn't work for me anymore. Just loads a blank white box: I've found this one to be more accurate than the random ones elsewhere, so hoping it's not permanently broken.

    LB7 LML Allison 1000 conversion & swap

    PCMPerformance is where I bought my 6 speed file. Sent from my CPH2655 using Tapatalk

    Injectors help.

    I've got a set of brand new SAC 45% injectors I'd let go for a fair price. Bought them from Brad but ended up going bigger, never even took them out of the bags. Sent from my CPH2655 using Tapatalk

    That's the most AI response I've seen from a company all day. Sigh. Sent from my CPH2655 using Tapatalk

    Now that's a cold engine bay! Kind of surprised how much snow accumulated under the hood. Sent from my CPH2655 using Tapatalk

    Transmission issue or wiring??

    The 5-speed Allison transmissions has a hydraulic failsafe where 3rd and reverse work fully mechanically when there is no electrical power, which is why your truck would drive once you unplugged the connector. If I were to guess, it would be the transmission connector filling up with fluid that...

    LB7 Possible sensor issues

    Key On Engine Off the MAF should be 0, or close to it. I think the value the OP saw is fine. Idling should be about 40 g/sec. Depending on the scan tool, some display MAP but call it boost. At sea level, MAP would be around 14.7 PSI. Sent from my CPH2655 using Tapatalk

    Bought, wrecked, rebuilding a 2009 LMM

    When I did my Duraburb in 2017 we couldn't find an easy spot for a fuel cooler, so I don't run one at all. Fuel temps are basically identical to my truck, even when the fuel light is on (fuel light takes 32 gallons to fill the 35 gallon tank). I don't tow heavy with the Suburban, but I do tow a...

    New PB

    Unfortunately I have been too busy to finish reverse engineering the GM OS that everyone converts to 6-speed so that I can freely give it away. However, I do have at least basically usable CAX files to edit 6-speed tunes, working with both DuramaxTuner and PCMPerformance files. PCMPerformance...

    I toggled the visibility, hopefully the video is working again now. Sent from my CPH2655 using Tapatalk

    New PB

    Got back to the track for my birthday a while back, and with a better launch, got it down to a 12.162 @ 111.58 MPH. Still 8,200 lbs give or take, so I am really fighting physics at this point. It might be fun to take some of the weight out just to get that 11.999 pass one of these days when I...

    Alternator staying on. Running a single Alt using second Alt trigger wire?

    Yeah, it's weird. I suppose it could be a 2nd ECU with an issue that I bought. Hmm, I'll measure my blue truck and my brother's truck and see what they show for voltage on that wire to compare. Neither of them has a battery drain, so that should be telling. Sent from my CPH2655 using Tapatalk

    Alternator staying on. Running a single Alt using second Alt trigger wire?

    Perhaps relevant, but I've been trying to diagnose this on my LB7 as well, and I did end up swapping ECUs, but both ECUs behaved exactly the same. Thinking back, this also started when I swapped alternators after the OEM one died. Maybe the newer regulator modules they're building alternators...

    Seriously?

    The oiled/washable style filters make a ton of sense on gas rigs because they're throttled and only move the air they use. I actually get 50k miles or more between cleanings on my car. But diesels flow a ton of air, and I am lucky to get 10k miles before I have to wash the filter. If I could...

    Sac 65

    I've put in 3 sets of LDS SAC45 (new not reman) injectors in the last 4 years and had 0 issues. Did a set last week on my personal Suburban. I am able to run the same tune file with the same result on all 3 rigs, so the set-to-set consistency seems really good. The matching between injectors in...

    LB7 LML Allison 1000 conversion & swap

    I recall my transmission guy saying there's one additional hole drilled in the separator plate vs. a 5 speed. If you have access to a Suncoast conversion you could pull it apart and see where and how big that hole is. Sent from my CPH2655 using Tapatalk

    Need help with a LB7 / LBZ conversion truck in SW NY state.

    Didn't James or someone just report a similar issue where a truck wouldn't run despite all signs pointing to it working and it turned out the diesel was mostly water and wouldn't burn? I wonder if something similar is happening here? Sent from my CPH2655 using Tapatalk

    Scan logs not populating correct rail pressure

    It looks like your log file is in PSI (SAE) but the tune table is in MPa (Metric). I believe they both have to match to highlight correctly. Sent from my CPH2655 using Tapatalk

    Rearview Mirror

    Is the problem it dims randomly, or the display will turn off or start flickering? The flickering/rebooting display is very common, and I usually just get a lower mile mirror on eBay. They are all made by Gentex, and if you search for the Gentex part number (should be on the front/windshield...

    Need help with a LB7 / LBZ conversion truck in SW NY state.

    As long as one of them tracks the actual pedal position, then I think you're good. I just saw it pegged at 100% and thought it might be your problem if so. Otherwise I'm out of ideas, sorry. Sent from my CPH2655 using Tapatalk
