    Physical ethanol sensor speed?

    Hmm The way you have phrased it, tuning is a one-shot process? Not something that can be further tweaked in real time. I don't mean to keep referring to Ford, but is what I have (some) experience with. Using a Bully Dog, had all kinds of access to engine management on a 01 F250 7.3L. Injection...

    Physical ethanol sensor speed?

    My Yukon is 2012 SLT with 5.3L 6spd, and has 199k miles, possibly 200k now, on the clock. I fill up at a single station, typically at same dispenser on same side when local. Yeah, station is Walmart / Murphy, but works for me. Torque typically reports ethanol in 5-8% range, with a couple Spikes...

    Physical ethanol sensor speed?

    You know what, it is probably virtual. As far as I know, nothing has been added to the Yukon. Searched for pn and location @ gmparts and doesn't exist, at least not for flex fuel sensor like was on my old 03 pickup. An aside: My '03 Silverado had an actual sensor that had to be replaced a few...

    Rear AC alternative controls

    Making progress towards an electric compressor on rear AC. Most still on paper, though have compressor / condenser worked out. Compressor is variable speed based on ambient, interior, and setpoint temperatures. Setpoint temperature has output from controller for condenser fan and evaporator...

    Physical ethanol sensor speed?

    Bit late but... My 2012 yukon slt takes a while/ bit of a drive before I can see any change on Torque Pro. 20 minutes, 15 miles highway driving is typical, or few miles of city driving with stop lights. I fill the tank when gets around half, per torque pro, not dash guage. Might be adding...

    GPS Data Source, HD Radio

    Working out a custom android head unit using a tiny / micro pc (like lenovo m600 w/ J3710). I know I can get gps nema stream using a USB dongle, and there are usb and serial adapters as well. But, our vehicles have gps already for onstar to use. Anybody figured out how to pull / intercept the...

    Planned Mods

    Ugh, recovering from somebody getting into my computer. Seat Warmer: I can only choose (manually) seat or back, each having 3 levels. Remote start is only seat unless left in back when turned off. Cannot choose both. Heated steering wheel. That would be nice, but would likely end up...

    Planned Mods

    During the terrible freezing temps, I still had to drive. Let me tell you, driving in 27F is no fun :) Seriously, I was surprised that could switch from fresh to recirc while was waiting at a stoplight (with only me present). On a whim, reached over, pushed button, and surprised when got steady...

    Planned Mods

    Extra battery power is for additional lighting, inverter, and electric rear hvac compressor, onboard air compressor (not suspension). I already have the LFPs, though considering increasing to 3 x 100Ah. -Starting (charge occasionally) Cab / Vehicle, and Toys / rear hvac compressor & fan.

    Planned Mods

    Yeah, I have noticed recirc locked out as well. Figure is function of temperature and humidity. You are right about turning off while driving. I have been idling at lights and heard mechanism change over. First time, didn't know what it was until felt air blowing get few degrees warmer. This...

    Planned Mods

    Computer fans are what I had in mind. Would prefer to fit inside cavity, will just have to see what I can work with. Surprisingly, the flaps are still in good shape. Every 1 or 2 quarters, I pull off the fascia / trim pieces to replace the pieces of EPDM foam Imused to eliminate squeaks. What...

    Planned Mods

    Victim is 2012 Yukon SLT... -Going to be adding a pwm box to alternator to better support LFP battery(s). Saw 15.2vdc on torque pro, last night. Had for a while, too busy to fuss with and is my Daily Abuser. -Add a pair of EcoFlow 12v 100Ah LFP batteries. Will be shoe horned for sure...

    OBD2 / CAN adapter

    Ordered one and received yesterday. Just got busy with work, will have to wait to play. We're you using 5vdc or battery voltage? Read up more about the CS alternators, models go both ways. Probably will put my fluke on existing oem harness and see what average and peak voltage to alternator...

    OBD2 / CAN adapter

    Wasnt able to find what you mentioned. Do you have a link to such device? HPTuner would be nice, but need to address issue of failing adapter first. OBDLink has offered an OBDLink EX, but it doesnt do SW-CAN and I declined. The *EX is cabled, not BT. Still looking for cabled solution to...
