    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Step 1 was putting eyes on the ABS/EBCM module. Thanks to whoever provide the physical location of that thing; it's along the frame-rail under the between the driver's doors. Now that I have a starting point, I can lift up the car, and start looking for physical damage to the loom & wires...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Looks like (after a cursory glance) all the U-codes are related to modules not talking. I love how there were were zero issues before the motor swap..... Such is life.

    Plugged the AutoCal V3 in to pull the codes:

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    While digging around for loose wires and other dumb stuff I ripped out the smoked front diff. and slammed in the replacement. I drained the old fluid from the replacement before bench-pressing it up into position - every ounce counts - and was happy to see that it was fairly clean & no...

    For the grounds.... How many are there for the engine bay? One at the back of the driver's-side cylinder head. One on the bottom of the block, behind the PS pump. One on the front of the passenger's side cylinder head. Anywhere else?

    I want to ignore codes at this point, and focus on grounds. The ABS system is offline, and I need to ensure that it's working first.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I'm trying to figure out why I have the ABS, TCS, BRAKE lights on my dash. Both front wheel speed sensors are tight... I triple-checked harness connections this morning. I want to see if the ABS controller is sensing the left & right sensors, but that particular function isn't working in the...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I was dumb, and didn't add the CANdi module inline with the OBD2 cable. But I also had a bent serial port pin on the Tech2, so I had to fix that. Now it's connected! Question: how do I access the ABS system? I can see the live ECU data, but when I open the F0: VSES Data or F1: Signal Data it...

    I was attempting to read the DTCs.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I'm done with car stuff for the day, bit I'll try again tomorrow. The directions said to only use OBD power, so maybe that was the issue.

    So, already off to a rough start. Something about "CANdi not connected" after ensuring all OBD2 and power connectors solid.

    It did come with an envelope full of DIY labels.

    Tech2 showed up, all the way from the Big Rock Candy Mountain store, some assumptions required.

    Tires out of round?

    My Black Rhino wheels are like this. They have a ~120mm wheel bore, and the previous owner had NO concentric/hubcentric spacers installed! He was relying on the lug nuts to center the wheel to the hub, and the studs to support the vehicle weight.... I found a set that centered the wheel, and...

    Lower Ball Joints Recommendation

    Where did you order from? It's about time I do my front upper/lower everything.

    Tires out of round?

    Dumb question, but are your wheel bores the same diameter as your hub bores?

    $500 - 2014 5.3 engine & random parts. New Hampshire

    https://nh.craigslist.org/pts/d/ascutney-ls-engine-179k-miles/7776975676.html Probably a huge long-shot, but might as well post this here. Dealing with the bot/scammers/morons on FB Marketplace is tiring.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    That seems almost doable. I just wish there was a data/spec sheet somewhere. I'm waiting to hear back from BBP to see which sensor they assumed would be installed for the 6.0 basemap flashed to the 5.3 ECU. Back when I used to do some basic Saab tuning, I had a nice variable power supply to...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    1st oil change on the new engine. However, I've spent hours trying to find the answer to whether there is a signal or reference difference between old & new MAP sensors, other than the difference in their physical shapes.

    Coolant Leak

    It is comically simple. Just remove the hose on the left side of the crossover pipe. Remove both 10mm bolts. Pull off the crossover pipe, and replace o-rings. Reinstall it all. You might want to crack the overflow tank cap to release any built-up pressure in the system so you don't spray...

    MAP Sensor question: 2008 6.0 vs. 2014 5.3 - same parameters?

    I've been searching for an answer online, and emailed BBP, but am hoping someone here can possibly share some info. Since there are physical differences between the newer style 2014 5.3 MAP sensor: https://www.rockauto.com/en/moreinfo.php?pk=12648337&cc=3305736&pt=11207&jsn=470 and the older...

    Do you, or anyone else, know what sort of programing options are available with this?
