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

    I believe it will still charge at the higher voltages, my impression was the RVC sensor tells the computer how much juice you are using to generate just enough juice to keep from charging your battery as often/much? Will be disconnecting mine. Keeping an eye on voltages and battery SOC in the...

    Random driveline clunk when accelerating from a full stop

    I tried without disconnecting steering, but could not wiggle the mount out of there! Now on the pass side..starter out, heatshields off, bolts out (that front lower one was fun, swivel head 72 tooth was useful) and mount is loose! BUT looking like exhaust manifold has to come out.. unless I...

    Pedal commander who’s got one?

    FWIW, when using HPTuners, I cannot change the accelerator pedal/throttle angle map without it triggering a REP. I made some changes upto around 10%-15%. Have heard smaller changes might sneak by, but some other setting checks throttle/accelerator position and triggered a REP. The REP mode is so...

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

    I've been looking into the same. So far I've tuned the charging to not drop below 13.5V, but am thinking about unplugging the current sensor. I am guessing that without the current sensor, it might be less skimpy with the charging. From what I can tell, undercharging seems to be the main issue...

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

    'Finished' installing driver side H3 motor mount! Original was torn all the way across. Next week maybe I'll get to the passenger side.. Updated my transmission tune with shift points from a 2015 tahoe (3.08). Noticed the PPV 2015 Tahoe has earlier shift points than regular 2015 tahoes by 1-2...

    Door/warning chime/turn signal click no longer working - 2008 Yukon Denali

    LMK if it works! But then you have to disable the park assist everytime? Plus no turn signals? Doesn't sound right.. I've already removed my park assist button and module..

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

    My thinking was, if the coolant cap can't hold it's rated pressure, temp may go up. I see 194-201 warmed up, I *thought* my temps were more stable around 194 before I installed all new cooling system.. (melling water pump, OEM t-stat, Denso radiator, cheap coolant tank/cap) Usually when it does...

    5v ref issue

    5V ref should be 5V. Sensor signal would be a different wire that could be anything (less than 5V ref)

    5v ref issue

    Am I reading it right, that the starter will self crank after turning off the motor? That does seem odd that there are no RPMs with the cam sensor disconnected. Definately check the wiring to cam sensor! (sounds like you may have already) Also, looking at J91z28d1's attachment, it seems like...

    07 tahoe z71 BILSTEIN rear shock

    07 Tahoe, Tahoe starts Jerking when braking and or accelerating.

    Just spin the wheel to see if you feel any roughness and push/pull the top/bottom of wheel to check for play

    Yep, please let us know if that code has been cleared and has come back as someone mentioned in your other thread.

    Ac problems

    Might be worth a try to disconnect the battery for some time? When you start it back up, do not touch the climate controls for a minute (I believe it's supposedly ~40 seconds) where it should automatically do a relearn procedure..?

    Front Upper Control Arm Bushing Replacement?

    Upper arm does what you describe Hole is slotted, so adjusters move upper arm to adjust camber/caster. I like to hammer both sides of the knuckle (simultaneously, mini sledge or heavier hammer better) around tie rod (and balljoint) holes to break them loose. Keeps from chewing up boots or...
