    HVAC problem with UAS upgrade in '18 truck

    No special cables, I just used OBD MX+. You can put the actuators through a calibration process. This is basically a learn span, where the actuator is commanded to full close and full open for the control module to learn the end stops, as well as a count between end stops. It was interesting...

    Debating on Tires...

    I'm planning to run the G2 next on my ram. It's the only P-metric 275/65-20 I can find. I want to bump up to a 34" tire, but don't want the weight of an LT tire. Sent from my SM-G965U using Tapatalk

    Debating on Tires...

    I've ran the Wildpeak A/T3W on my '15 2wd ram for about 18k miles now, and the Goodyear ultraterrain AT on my wife's '17 4wd Yukon for about 3k miles. Despite the far better sound deadening package on the Yukon, it still has more road noise than my ram with the ultraterrain. I almost...

    How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM

    Yes, mine will occasionally lock up and do this. Battery pull doesn't always fix it. The only solution I've found is to do a reset on the radio, clearing all personal information. After resetting, the radio GPS thinks it's at infotainment.com's location (where mine came from), but quickly...

    Better flowing intake for 5.7 w/Ecodiesel lower airbox

    The Eco does not use more air, all things being equal it would need to produce ~28psi boost to even use the same air flow as the 5.7. Turbochargers are sensitive to intake depression (pressure drop) for a couple reasons. First, compressor efficiency. Intake temps would increase with a more...

    How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM

    Along with the necessary harness to tie in the temp and humidity sensor, yes. So far, it's the only solution that has worked 100% of the time ( not a very large data set though). I would consider starting with just alpha and switching the HVAC configuration to something other than SZMTC...

    HVAC problem with UAS upgrade in '18 truck

    It's not needed if you're using the Obdlink MX. If I understand correctly, it is needed with other OBD adapters. Sent from my SM-G965U using Tapatalk

    HVAC problem with UAS upgrade in '18 truck

    You're correct, I wasn't attempting to call the '18 module a fix. It appears folks are having better success with it as compared to the version being shipped with their kits.....though I hate making statemens like that without more data by points. Sent from my SM-G965U using Tapatalk

    HVAC problem with UAS upgrade in '18 truck

    Curious if any of the seasoned technical folks on this forum have can sniffing and analyzing abilities? I'm very curious what the data stream looks like when controlling temperature using single zone MTC as compared to using single zone ATC in manual mode. Sent from my SM-G965U using Tapatalk

    HVAC problem with UAS upgrade in '18 truck

    Interesting. I saw no change when running the calibration, it would pass successfully every time, and I could watch the temperature blend door actuator spanning the full range. I used the option under the settings in the attached pic, using "MY>12". One thought is to push on @Infotainment.com...

    HVAC problem with UAS upgrade in '18 truck

    Not discounting your question, as I've wondered the same, but the process can be sped up considerably by removing the battery cables and touching them together. I went from single zone MTC to dual zone ATC to single zone ATC in about 10 minutes using this method. Sent from my SM-G965U using...

    HVAC problem with UAS upgrade in '18 truck

    Hold tight, going to try again tomorrow. Was having an issue with the ambient temperature sensor ( leave those settings alone!) that another member just helped me resolve. This would have impacted the function of the ATC. More testing tomorrow. Sent from my SM-G965U using Tapatalk

    And I thought I had been keeping up on this thread! Fixed it, thank you! I was missing "ambient temperature sensor present". Set it back to no, mil went out immediately and outside temp displayed. Sent from my SM-G965U using Tapatalk

    HVAC problem with UAS upgrade in '18 truck

    Well, I tried everything listed above, and the problem is still there. When trying to run single zone ATC, the slider will span the entire range, but anything above "low" ( full cold) goes to full hot (with auto toggled off). Sent from my SM-G965U using Tapatalk
