There is something to that... I noticed that under regen braking, if you hit a significant bump, there can be a shudder/judder. Possibly when one or both front wheels traction changes suddenly, where the regen software is trying (badly) to adjust accordingly. Also notice d similar judder in...

In North TX, we're lucky if we get 4 yrs out a battery, flooded or AGM.

Correct. It *seems* that engineers assumed vehicles would be driven often enough and far enough to keep the 12v battery within 60% +/- state of charge, which, we might guess, they determined is the sweet spot for MPG, 12v battery reserve capacity, battery longevity, etc. For example, my...

I don't think it's the battery choice as much as Ford's management strategy of the battery; i.e. the forthcoming software update.

Well, maybe not. The fallacy of catch cans, IMO, is few know how much oil mist makes it past one or two catch cans. i.e. the OEM may be the only one able to measure how much oil is lost via PCV path, vs past rings, valve stems, etc. vs engine hours or over a typical OCI. Then, and only then...

Any fresh news on this recall?

To that point....the Valvoline Restore & Protect oil apparently helps or eliminates intake valve deposits as enough oil mist make its way through the PCV system over time on most vehicles to soften/loosen and then prevent build up of deposits for direct injection engines. The product is also SP...

It's in denial--85F on Dec 23 does not pass the rational part of the algorithm. :crazy:

Hey Dick ;), I have a quick acting thermocouple meter, that I know to be +/-1% over a fairly wide range. which I can place outside the window in the air stream to monitor temp. As I have a freeway commute, I've taken readings in Winter, Summer, sunny days, cloudy days. Vehicle pretty...

Ah, so from the OP information, what is "plausible" since you are vetting that for the thread? I took a photo of the stock XL/XLT dash tweet (8 ohm, 12.5w made in China). As I'm in a marathon videconf right now, I eventually found a thread by snowkarver where he captured the stock door speaker...

So my comments still apply in principal; a 4 ohm dash tweet in parallel with an aftermarket 4 ohm door speaker, may be disagreeable to the amp circuit, especially if the tweet impedance dips low where it overlaps a low impedance point with the door speaker. Anyone come across Z sweeps of the...

Yes, that is my ask; a post link to that info, rather than sifting through random threads for "ohms" or something. The dash tweets were actually impedance marked.

Visual proof of that (for reasons other than this thread)?

@ChefJeff789 Guessing the OEM amplifier is unhappy with the new 4 ohm front door speakers and 4 ohm tweets-- their spec sheet impedance. I know the OEM dash tweets are 8 ohm, and guessing the OEM doors speakers are as well. The door speaker and dash tweet is in parallel on the OEM speaker...

I'm content to wait until @OldSarg reports back in--assuming we haven't humiliated him into silence--re: what the dealer, repair center, etc say about the incident.

I totally missed this--will have to connect Forscan and take a look! Thanks for posting!

Oddly, I saw LED lamp failures (DRL and headlamps) on Mercedes and Nissans first, years ago, then some GM CUV's. Once you look for them, you see more of them. Of course, you can have a false positive for some vehicles that shutoff the DRL's on the side that has a flashing turn signal. And of...

Or, you can do oil analysis (as I did) and make your decision on actual *facts* for YOUR Mav, YOUR driving scenario, YOUR driving conditions. For mine, I did an analysis at 10k mi on the Ford 0w-20 the dealer put in it when I bought it (@ odo 4k). The results were very good all the way across...

Anyone figure out how to reset learned values WITHOUT using the Ford or spendy aftermarket scan tool? e.g using Forscan?
