I generally reset the trip each way, but decided to get a round trip view, since there are a variety of mountains on this trip and end at different elevations.   Observations... I was on track to equal the EPA highway rating (even though that really isn't interstate driving if you look at the cycle) of 29mpg until: 10 minutes of 30-40 sustained, 60+ gusts of wind (and sand storm) dropped the average from 28.5 to 28 20(ish) seconds of WOT up a hill to get out of a bad situation developing (2 semis that couldn't maintain their lanes) dropped it from 28 to 27 This trip starts at 2200 ft elevation, tops out at around 5000 ft, and ends at 3900 ft The average speed of 77 mph is on par with what I usually average on this trip, as it is 98% interstate, 2 times 75>65 in city, and about 10 miles of highway at 65>55 I can knock 1 mpg off my average over 300 miles simply being aggressive getting on the interstate on a short on ramp (but I won't try merging at 35 mph either)   Overall not bad for fuel mileage, but it is very easy to blow it up, winds really affect it, as does accelerating to pass people, especially over hills. Adaptive Cruise and being alert but not overdoing it goes a long ways. I would love to say I could set the cruise at 75 and just do that, but with the hills, semis, wrecks towing wrecks (people that buy cheap cars and drag them to Mexico/Guatemala), 75 mph is just...hard to maintain without speeding up and slowing down.   I could easily get 30/31 mpg on this drive in my 2017 Escape with the 1.5. But I could also get really terrible mileage with wind, which is a big issue on this drive. I would get 25 mpg in my 2000 Grand Marquis (which I miss).

The new Livernois tune seems to shift pretty well. At least a lot better than stock.

They mentioned stage 5 and it came out a few weeks before I did my last run

2024 Edge Workshop Manual - China region...   Placing your device cursor over underlined acronyms may yield popup full-words meanings for acronyms.   Auto Hold The auto hold feature is activated and deactivated through the use of the auto hold switch located on the FCIM . For the system to activate, the vehicle must not be moving, the driver safety belt must be buckled and the driver door must be closed.   The ABS module receives the driver safety belt buckle status from the RCM and driver door status from the BCM , while brake system pressure and the wheel speed are received from ABS sensors. This information allows the ABS module to determine if the vehicle is stopped. Once the previous conditions have been met the auto hold feature can be activated. When the switch is pressed, the FCIM receives a ground signal from the auto hold switch and sends an auto hold message to the GWM over the HS-CAN3 . The GWM relays the message to the ABS module over the FD-CAN .   The ABS module then sends a message to the instrument cluster through the GWM indicating the auto hold feature has been activated and the instrument cluster illuminates the auto hold indicator.   The auto hold indicator illuminates when the IPC receives a message from the ABS module through the GWM .   Once the auto hold feature is activated and the driver presses the brake pedal, the ABS module closes the isolation valves in the HCU to maintain the current brake system pressure at the wheel ends. The ABS module maintains the pressure until the driver presses the accelerator pedal, shifts the transmission into PARK or after a specific time limit has been reached. The ABS module engages the parking brake after 2-10 minutes, depending on the grade of incline the vehicle is currently stopped on, the steeper the grade, the shorter the time.   Auto Hold Switch The auto hold switch is a momentary contact, push button switch and is part of the FCIM .   Normal Operation and Fault Conditions Vehicles equipped with EPB are also equipped with an auto hold feature. This feature must be enabled by the driver by pressing the auto hold switch once the driver seatbelt is buckled and the driver door is closed.   Pressing the auto hold switch in the FCIM enables the auto hold feature, but does not activate auto hold. When the switch is pressed, the FCIM sends a message to the ABS module indicating the system has been enabled. The ABS module then waits for messages from the RCM and BCM as well as ABS sensor information to indicate the auto hold feature can be activated. Once all criteria has been met, the ABS module activates the auto hold feature.   In the case of a system error, the instrument cluster displays messages and icons.   China region Search-function is not locating Auto Hold switch and other FCIM controls in Wiring Diagrams or Workshop Manual procedures, and no China-region Owner's Manual is shown.   Hopefully, the above verbiage provides you sufficient Auto Hold awareness at this stage of your inquiry.   Good luck!  

Anything for the 2019-2024 7 seat Edge?

Do you know the version number of the tune or when it was released?   On the Edge Sport (2015-2018) seems they stopped at stage 4 released long time ago (2021). 

Well I pulled the rear driveshaft Thursday. Was not sure what to expect, I was kinda halfway thinking the system would act like an open differential and I would have no movement at all. But, the car drives just fine with no ill effects it seems. I drove it around this past weekend and into work this morning with no issues. Good news is that the vibration at 25mph is all but gone so it does appear to have been the driveshaft. I think that maybe the splined connections need to be staked or upset such that they do not slide in/out. Instead of that motion being taken up by the flexible connection at the PTU the relative in/out movement was happening in the splines resulting in limited engagement. At least that is what I think. Pretty sure FMC never intended anyone to rebuild the driveshaft. I would like to have AWD at least for next winter so I will noodle on this a bit and hopefully come up with a cheap fix. Not a lot of room to get in there and stake the splines. Anyway the bad vibration is gone for now. However, every time I fix something another noise that was masked comes to the top of the spectrum. I am getting a howling noise at speed. it's not bad at this point so I am not overly concerned.  On another note, the right rear tire has significant cupping on the inside, a product of worn out bushings. Not sure I want to tackle that as it could put me down the rabbit hole of multiple parts replacements. Might just rotate the tires and spread that joy around to the other three tires.  New goal is to get through summer with the car, stretch goal is to hit 300K. Gonna get my $200 initial investment back out if it kills me. 

Link to this FordParts webpage         Good luck!  

For that VIN and generally for 2020 Edge -- which is the latest listed model year shown -- no mention or depiction of AutoHold switch or circuits/connectors in the China region Wiring Resource, though the China region Workshop Manual includes identification of the Instrument Panel Cluster's AutoHold Reconfigurable TellTale (RTT) indicator lamp in an IPC illustration...     ...and as you mentioned previously, a single reference to AutoHold in the China region HTML format Owner's Manual, which is the only format in which the Owner's Manual is offered...     Good luck!  

A few days ago fairly deep water on the road caught me by surprise - I checked under the car to see if any of the flimsy splash guards were damaged but saw nothing.   Today while doing an oil change I notice a small plastic shield was damaged - I've used epoxy and thin wire to get it back together but would like to know the part number and price.
