    Issue at a gas station

    Do the Gmt800 trucks use the same style charcoal canister as the gmt900 trucks? My 2001 has the original charcoal canister and evap line/system and have never had any kind of problems like this at ~260k miles. Also has original coil packs, exhaust, cats, muffler

    AFM Disable Options

    Well I haven't driven far since it's been reset. Yesterday 1.5 miles to work, then ran by Costco on way home from work, which is maybe 2 miles away, then back up to work to pick up my daughter who stayed after till 5:15. Then to/from work today. So maybe 10 miles and no highway cruising in the...

    AFM Disable Options

    It's only been 2 days and while some of my readiness tests are complete, 3 still are not. It looks as though the AutoSync doesn't fool the ECU like the Range device does as described earlier. I'll keep checking the readiness monitors after each drive cycle though, but I'm flying out of town on...

    AFM Disable Options

    Yeah, I only created a Facebook account so I can join/post in that group, and that's all I use it for. I only go on there if I'm having a problem with something on the AutoSync, like when there is a firmware update and some settings change and I can't figure out what happened.

    AFM Disable Options

    I'm just doing this as an experiment, to see if the Autosync's way of disabling the AFM will allow the readiness monitors to set, or if it keeps them "not ready" like a Range AFM device does. It doesn't flash the ECM like a tune does, so I'm guessing it just fools the AFM system either into...

    AFM Disable Options

    I just re-enabled AFM in the tune and also checked the readiness monitors and they're showing as "incomplete", as they should after flashing the tune. I have the AutoSync set to disable AFM. Now I just have to drive it for a few days and check the readiness monitors and see if they ever...

    I cannot believe it!

    Maybe it had ALL the maintenance records and paperwork from the past 20 years

    That bolt head is definitely rubbing that axle shaft. You can also get spacers for the top of the strut, so you don't have to run as large of one on the bottom and still get the lift you want.

    Oil pressure drop after addition of OEM Oil Cooler?

    @j91z28d1 that oil cooler bypass you linked earlier looks just like the oil filter bypass that's listed on RockAuto for my 2001 5.3l Yukon A different part # though

    AFM Disable Options

    Very informative post on how the dongle disables the AFM. I'd be curious as to how the Btdieselworks AutoSync does it and if it uses the same process. I might re-enable AFM in my tune with the Diablo intune i3 I use and disable the AFM using the AutoSync on its splitter cable and after about...

    Oil pressure drop after addition of OEM Oil Cooler?

    Many specialized aftermarket pans made for road racing or drag racing have baffles located at different places (depending if you corner or are going straight with a lot of Gs) to help keep oil around the oil pickup tube in these situations. Kind of like how a fuel tank has a reservoir area...

    Oil pressure drop after addition of OEM Oil Cooler?

    Weird, the listed vehicles this valve fits is 80s-mid 90s trucks/suvs and 2006-2014 vettes. I wonder what's different on ~2000+ trucks/SUVs that this isn't used.

    Oil pressure drop after addition of OEM Oil Cooler?

    The MotorTrend show Engine Masters did an episode testing the amount of engine oil in the pan with an engine on the dyno. S3 E3 How Oil Kills Power. Basically seeing the effects of more or less oil has on hp and oil pressure across the entire rpm range. A pan filled with the oil at the...

    Oil pressure drop after addition of OEM Oil Cooler?

    That's called windage (not the same as in gun sights). They make pans with baffles or "windage trays" that bolt-on to help with this oil frothing. It can be a problem and cause loss of pressure at higher rpms

    Oil pressure drop after addition of OEM Oil Cooler?

    I never knew that was a valve. I know it's not adjustable and that there is an o-ring under it that can start leaking and need replacing. I just thought it was a blocked off port for some unknown application, lol Most people on here don't know what that port is for either, it's been discussed...

    Oil pressure drop after addition of OEM Oil Cooler?

    There's no adjustment valve on an OE one. Dang that's expensive, guess it's a vette thing, lol. More than likely because of the valve? A GM oil cooler line from RockAuto is $67

    Extend range on key FOB

    A lot different in size, lol. I guess none of mine have gotten to the crappy range point yet. They still work from anywhere in my house or the other side of a parking lot.

    Extend range on key FOB

    Still big and square compared to an OE ~99-14 teardrop shaped fob if you ask me. I like small rounded fobs, lol 02 mustang fob, although square it's small and rounded 01 yukon fob 12 yukon fob 15 Acadia fob All original, OE

    AFM Disable Options

    It's fine. I really haven't used it much on the Yukon since getting it and uploading the performance tune and turning off DOD/AFM and the speed limiters. It's been a couple years actually and might be time to break it out and play around with some other things, like shift points and pressures or...
