Were the overflow incidences at the same pump? If you're putting the nozzle in all the way, it's going to be the nozzle's fault if it overflows on/prior to the first click. I have a 17 with 35k and don't think I've ever had an overfill.
Pretty much spot on. One thing I'll add because it worried me for a little bit. I put mine at 35 psi cold (it was close to freezing), but driving down the road on a trip my tires would all easily reach 41+ psi. Well I got concerned about overinflation until I looked at the tire rating. My stock tires are rated for 44 psi cold. So overinflation of the tire isn't going to be an issue if you only air up to 35 psi.
I thought they calculated fuel mileage based off the mass air flow sensor, hence why it's always so unreliable. It would make sense if they measured fuel, but I didn't think there was a fuel flow sensor.
I wouldn't think gearing would matter. I thought speed and mileage were calculated by wheel speed sensors. For the gearing to matter, they'd have to calculate mileage based on engine RPM, transmission gear, rear gearing, and tire size. Wheel speed sensor just needs tire size.
It's an all around mess. It would require switches, programming, and I believe motors (the motors have to support feedback for auto up). GM Upfitters has wiring diagrams you can look through. It's a digital signal from the driver's side switches, to the BCM, to the other switch, then to the motor (if I'm remembering correctly). I was looking because I'd like a single switch to control all the windows, but didn't figure out a good way other than running wires to all four motors.
I'm looking for something for the rear window for the same reason but can't find anything. A tip though, I have these for my side windows: https://www.walmart.com/ip/Safe-Fit-Safe-Temp-Cling-Shades-Extra-Large-2-PK-2-0-PACK/44965620. They just cling to the windows and I cut the little temperature thing out allowing full use of the windows. I just have no desire to stick a bunch of them across the rear window.
aero10 replied to papageoff's topic in Trailers, Hitches, & TowingI've had good experience with 1/2 ton trucks and weight distributing hitches. I'm not sure how you're attaching your chains, but an easy way is to hook up the trailer and then jack the trailer and truck up, hook up the chains, then lower everything. You can measure the rear wheel wells with no load and then adjust the chains to where you're at the same height with the trailer attached.
That's a pretty standard price across dealerships. Ford and GM both use programmed keys, I don't know about FCA but would think they would. Safety is why they require two keys to do it yourself; otherwise, anyone you lent a key to could make their own. With that said, since FORScan is available for Ford's, they can be programmed without two keys. Unfortunately I've been unable to find a GM equivalent to FORScan.
