    Fuel Economy Tanked

    The 15 minute warm ups sure won’t help fuel economy especially on short trips, will also cause sooner DPF regens that pull down the short term average as well due to the fuel injected into the exhaust system to help burn out the soot buildup. I get regens about every 250 to 300 miles on combined...

    Is it possible to get second row bench seat with the LZ0 engine?

    I have been trying to spec out a suburban or Yukon xl with the LZO duramax and second row bench seat. When I delete the buckets it deletes the LZO as well on any of the trim levels. Seems it was this way in 2025 as well, but I may be wrong, if anyone has a 2025 or has ordered a 2026 with the...

    Infotainment Navigation intermittent - My 22 Tahoe

    I’ve had similar issues with the gps not tracking as well as the navigation app won’t come up on the screen at all. If you select it it just goes back to the selection screen. I do a system reboot using the phone off button on the steering wheel. You need to have the vehicle running but stopped...

    Looking for GPS

    Had the same thing happen to my 2022. I pushed the onstar button and they walked me thru some settings menus and had me do a cache/memory clear on google maps app and it has been fine since. I’ll try to video the process if I can remember how onstar got me there.

    3.0 Duramax Camshaft Drive Sprocket Replacement

    I watched a youtube of a LM2 teardown after the engine had been replaced due to a failure at around 150K miles. What they found was the cam chains were very loose and the timing of the cams/valves had changed to where the valves were pounding into the top of the pistons, then causing a rod to...

    DEF level sensor issue

    I have a 2022 and have used 2- 2 1/2 gallon jugs in just over 13,000 miles and is still showing 75% on Banks gauge. I estimate that is about a 1/2 gallon per thousand miles, no towing.

    Banks iDash parameters for the LM2

    Link below for the 1.24.7 iDash software is a beta so be sure to backup your gauge before installing. You can go back to a previous version if you have issues with this version. This was posted on the duramax forum and was noted that it had some updates for the LZO. As I said it didn’t seem to...

    Banks iDash parameters for the LM2

    I am using the Dmax LM2 setting and I do have the dpf% and the gear display. I also can get the trans temp but don’t have it selected as I can get it on the DIC. There is a v1.24.7 software out but not on the banks site. Someone has a link to it elsewhere, I’ll see if I can find it again. Did...

    A/C Snowflake light on but compressor does not run

    85, 86 and 30 should all show “hot” or 12V to ground if the relay is not on. Relay will only be on when the ecu connects 86 to ground. 87, the fuse and compressor clutch will only have 12V when the relay is on. There is more than just the Freon charge pressure that the ecu looks at before it...
