The most capable tire is the tallest, skinniest tire that will fit under the fender, assuming comparable tread and durability among the options. Everything else is puffery.

It would be a fun experiment and I've thought about it. AUX delete is probably the better option. Ballpark, the capacitor bank would need to be capable of providing 20A for 1 second without dropping more than 1V. That’s 20 farads minimum, EDLC “super capacitor” territory. These are typically...

The Q1 comparisons might be misleading. There weren't many mid-size trucks to be had in Q1 2024. Plenty of Gladiator inventory, but the new Tacoma was delayed and there were no Rangers and few Colorados and Canyons on the lots for whatever reason. That may have benefited Nissan. The sales...

Not even close. Do we just make stuff up here? Ford truck sales are up 15% over Q1 last year. GM truck sales are up 11%. Toyota's are up 53% (*). Together these three sold 18% more trucks in Q1 2025 vs Q1 2024. In mid-size trucks, Ranger, Colorado and Canyon combined sales are up 123%. Toyota...

Stellantis reported US vehicle sales of 293,225 for Q1 2025, down 11.8% from 332,540 for Q1 2024. That includes 12,057 Gladiators, vs 12,989 in Q1 2024 (-6.5%). The release and pdf are here: https://media.stellantisnorthamerica.com/newsrelease.do?id=26695&mid=425...

Close enough. Grade is just algebraic slope, ∆y/∆x, and grade from degrees is just the trigonometric tangent. If I did it right, tan(20°) = 36.4% grade. I only just learned an interesting interpretation of grade: The grade at which an object begins to slide downhill is equal to the coefficient...

Only one of them has sections over 20 degrees, and It's only open to residents of the big island of Hawaii. The others only have short sections (200 meters at most) over 10 degrees. You're still confusing gradient and degrees, or at least ignoring it. The road you were on might have been a...

I wonder if anyone else has seen something like this. I've been holding off on the recall out of fear it will introduce additional problems. 30 degrees? There are no highways that steep in the US. Nothing even close. There are some short sections of streets with grades exceeding 30% (16.7...

FCA US reported Q4 2024 sales of 320,743 vs 343,552 for the prior year quarter. Total 2024 sales were 1,303,570 vs 1,527,090 in 2023. For Q4 Gladiator sold 9,453 units vs 13,660 in Q4 2023. For all of 2024, sales were 42,123 vs 55,188 in 2023. The report and pdf attachment are here...

In comparison, we have a 2013 Honda that draws twice the current of the JT and has only one-third the battery capacity. The Honda's first battery lasted over 7 years with no maintenance whatsoever. The second battery just hit the 4 year mark and appears healthy. It's not the quiescent draw that...

You know nothing if you haven’t measured it. So I did. About 300mAh per day for my 2023 with power nuthin. At that rate it would take 3 and a half weeks to discharge 10%, and well over 4 months to discharge to 50%. The average draw is around 13mA but it varies quite a bit over short and long...

Resistance of the IBS shunt is very close to 100uOhms. For some reason I thought it would be greater.

It seems that way to me as well. Even after long drives it still needs 1-2Ah. If you have a way to charge the battery and record the total charge accepted you'll be able to see if there's a trend. If it's taking more charge the longer you go from an IBS reset you'll know your theory is correct...

The >2V difference between N1 and N2, persisting over 100ms, is pretty convincing evidence that the relay joining them is not closed during the ESS restart. I wrote a lot of words before without making that point clearly. I've seen this too. The internal resistance model is completely...

I don't think so. It looks to me that the batteries are separated about 30ms before the starter relay closes and remain separated for cranking on the ESS restart. That apparent convergence before cranking is probably not the relay closing. The cold start shows what it looks like when both...

Here are two traces from a cheap handheld scope. It's more toy than tool, and spurious triggers are a real problem, but it fits alongside the battery under the hood and captures the difference between cold start and ESS restart. Yellow is MAIN, blue is AUX. Cold start: ESS restart:

@sharpsicle There's this zombie notion that the AUX battery powers the vehicle while stopped during an ESS event. It surfaces in just about every thread on the dual battery system. @jebiruph and @emiddio both repeated it in this thread within the last 24 hours. For my part, I started...

For the voltmeter, I used a pair of 2m silicone test leads with 4mm banana plugs on both ends. These are 2.5mm2, a little over 13AWG, and 2 meters is (just) long enough to reach from the HCFA to the passenger seat. I have a bunch of different crocodile clips and grabbers that take a 4mm banana...

@jebiruph cites Shane Smith, owner of Genesis Offroad. I have no idea what the whole disabling ESS after 6 stops has to do with anything. Nobody is claiming that the batteries are never isolated, just that they aren't isolated for very long. The statements I find relevant are these: This is...

@jebiruph Thank you for the response. @ShadowsPapa more or less said what I was going to, perhaps more. Let me just ask this: Do you know whether the PCR remains open for the duration of an ESS stop? Taking a step back: It is widely claimed on the JL and JT forums that for the duration of an...
