Auto Start Stop (ASS) Eliminator

[BettaRanga]

Thats strange, mine has been fine for 3 years now. I use one similar to these. Maybe try a different one?

Yeah but it's probably the cheapest mod I've posted. lol

Running the battery down after removing that plug it is the process I believe after the BMS detects low battery a few times. It will automatically shut off the ASS by the computer.

I believe the preferred way to disable the BMS in near the neg terminal- on the same cable where the temp sensor is , there is a conveniently placed 2 wire connector there. As the airline tech posted this may cause a fault to be detected and the charging voltage is then fixed at 14.5V - not an excessive charge in perhaps all but very extreme circumstances for an AGM battery. As I have pointed out several times this doesn't disable the vehicles charge regulation system, which is likely built into the ECU, like a phone battery charger, PC charger or most anything with a rechargeable battery when the battery is fully charged it halts the charging function. I've gone over a year sans BMS and some trips driven 8 hrs in 90F temps and to the best of my knowledge the battery has neither blown up nor expired because of overcharging. And it is the OEM battery and it tests as good.

For what it's worth, I bought a 2013 Chevy Malibu ECO in September, 2012. It came with ASS. Now ten years later I can report my worries about the starter failing early were unfounded. The car has 98K miles on it and I have replaced the battery twice. No way to shut the ASS off that I am aware of. I doubt it has saved me or the environment much but I have stopped fretting about it.

I usually disable the ASS when I drive my Ranger. That is for sure when I am towing the TT. I always try to let the Ranger idle a few minutes after stopping to cool down the turbo.

Not a great idea, according to a Ford tech.


I'm okay to hit the button when I start the truck.

Great vid!

I’m just glad the option to delete mine for a credit of $50 when I ordered it was available. For my new truck anyways.

Going by looks alone I'd say that dude may get a job offer or is stumping for one from the gents over at TFL, that squint seems to imply serious intent. Makes Clint Eastwood look like Captain Kangaroo .

So we're questioning a person's knowledge by his looks, to defend your position? You lost a little integrity right there.

That’s kind of the problem with society nowadays

According to the airline tech's research and another gent who courageously disconnected the BMS, charging voltages higher than 14.5 V have not been seen, I concur with that and have had my BMS disc'd for over a year now and battery remains healthy.

How do you quantify healthy?

Starts the car for one, but have a batt tester than shows internal resistance, voltage, does a load test and tells me it's in good condition. But batteries if anything can be unpredictable, good one day and give it up the next. Internal resistance is often a good indicator but not always.

Got to admit I didn't watch the video, and was more favorably receptive to the project farm vid testing of batts, he was organized, clean shop, good appearance but most importantly he made extremely proficient use of time and entirely focused on key pts, I'd surmise he spent time preparing and editing , very professional. Seen too many youtube vids that could learn from his video. Did you watch it ?

Not sure what vid you're talking about, but the guy you criticized, the Ford tech, seemed pretty legit to me. He was just making a valid point that the BMS may have more functions than just the ASS.

Well in jest I made fun of the still of him squinting my bad, fortunately I don't have to post a real pic of myself , but can't judge a book by its cover. I did hop around the vid , thought I heard him saying basically while under warranty don't mess with stuff, good advice for some and not unexpected considering the source. So my position or intent is not to prove smarter than ford engineers but to correct some misconceptions about amg batteries, their charging characteristics and what I know of charging systems, on the internet some info like agm batts have to be charged at lower voltage is a broad and not entirely correct generalization, or that disconnecting the bms will overcharge the battery. It is good to see someone post info about jeeps bms . Having once worked as an engineer you can be tasked with numerous objectives that can be conflicting and you have resource constraints , cost, time, material availability, etc. Seems to me the bms is an imperfect system, good in theory but too often falls short in real use. Does have some good features but I place higher priority on batt longevity.

ASS is the stupidest idea ever thought of to try to cut back on emissions

Yep. And I drive exclusively in sport mode to defeat it. the EPA can kiss my ASS.

FWIW, everything I have been able to read is that AGM batteries require a slightly higher charge voltage than flooded lead acid batteries, 14.1 to 14.5 is what I most often see compared to 13.8 to 14.1 for flooded lead acid. The reason is an 12 volt AGM battery has a slightly higher nominal full charge voltage.

Also, I have seen mentioned in both of the battery threads that have been prominent over the past few days the concept of three stage charging. That is true when you are talking about bench charging your battery. In the case of an alternator in a vehicle it needs to be constantly outputting enough current to match the demands placed on the battery by the electrical system and be able to recharge the battery when it is low. At an appropriate charge voltage of 14.1 to 14.5 volts a fully charged battery will not be over charged or overheat.

You mentioned that engineers "can be tasked" with conflicting requirements. Having been an engineer for over 45 years I will contend that they are always tasked with conflicting requirements and that every decision is a compromise.
