Yep - that's the published untrue spec based on math, not usage, they've always put out.
I guess make the engine sound better to those that don't know operation but know engine spec's and what sounds good?
Do people still look thru quick-compare charts with spec's for that to even be noticed now?
No disrespect - but you've had your head in the game of the intermittent battery drain too long.
This particular conversation and thread - if you catch the right posts - is clearly showing there is a charging strategy that has NOTHING to do with a battery drain issue.
It's not dismissing that...
Add in the fact that just like a normal tranny with resistance in lower gear may not be enough to maintain speed depending on incline.
The need to change from regen that could have been a decent amount and held the desired speed, to ICE air braking because the HVB is full - could result in much...
Oh - I meant can you see it in the OP picture where you saw the passenger one too high?
We all better be able to see the one on our own truck.
Yours really nailed it though.
Good theory.
Wanted to see just how good your eyes are.
I could only find the published spec's when I looked couple years ago - which is based on calculation of bore and stroke.
Not the fact a valve is open partway on compression meaning no compression.
Which I found very strange.
And if they drug their feet that long for a battery drain issue (obviously difficult to troubleshoot anyway) - I can only plan on them doing nothing about their BMS strategy of discharging a battery when it reaches 92% SOC for AGM or 85% SOC for SLA.
Preferring voltages closer to 12.1 than fully...
Since Atkinson compression is so low by design, not sure how any problem with pre-ign could happen that higher octane would solve.
ETA: Yes there have been plenty of posts of ones testing 91, especially towing with hybrid.
I recall (that's always dangerous) no comments of improvements, or...
Well shoot.
2 threads within the last week, at least - seemed to have this effect.
Don't recall their MY - but great to know.
This isn't the TSB 23-2209 from 2023 right, something newer?
Is it this?

Good eye!
After your comment I could see it too.
Now - can you see the driver side mark?
If it's on the mark at rest, but passenger isn't - dealership has a bit of movement to fix.
I've had both rest a tad high, and rest a tad low before.
And unrelated to me moving them for service position...
Interestingly the recall for extended warranty on the 22's, didn't start with the production start date.
Sounds like they did use a better one initially, then resorted to what you got.
And either found a new one or went back to the prior one.
There was a thread on that extended warranty recall...
Get ready for that with many other manufacturers.
Constant complaints of newish, or models where same parts are being used in new builds, having parts unavailable for replacements.
Pulling teeth to get them to dealers where they are needed.
So if you have an expected vehicle you are interested...
And some companies kept that policy going for newer cars that could have made it longer - but went ahead and switched the fleet out.
Got a couple of good late 90's cars that way - they easily went 150K, but were sold at 60/70K.
Maintenance records and such, just high mileage, and usually a good...
Tow/Haul isn't going to cause more regen then would be accomplished with the brake pedal, or the ICE running more to get up inclines.
What it does do is prioritizes have the HVB closer to the 70% SOC side rather than allowing the 30% side.
That way when extra power is needed - you got enough...
So you are watching the instantaneous MPG figure it sounds like.
That actually has very good accuracy - system is using how much grams of fuel is being used to the estimated tire rotation distance - both pretty specific figures.
But any variation in wind, or air temp, or humidity - will show...
Wow - can't believe the number of people that believe a change from "up to" (which likely means was) 10% ethanol to 15% ethanol would be meaningful in any short term manner.
Around here at least - permanent labels are normally "up to 10%" for the 87 Oct.
Did this math for another group saying...
Am I reading a thread from 3-4 years ago?
Feels like that.
I guess we haven't had enough keys locked in car threads to get the reminders out how this happens.
Due to drivers own hand.
And the caveats and differences with keyless entry.
And settings for unlock all or not on drivers door open.
Now there's a problem looking for a solution - to keep junk out better, or make it easier to clean out.
Now the cowl gutter screens do catch some of what ends up down there - of course a flap was already there.
@MABETT seems to be curious about places on truck that could use improvement.
Think...
85% on SLA batteries.
Seems 92% on AGM.
With no programming change required!
80% on SLA is when the float charge starts, close to 1/2 Amp.
87% on AGM I recall it being noted.
Of course - once it's lost it - throw that 80/87% out the window - the goal has changed.
Never mind full change...
