Feds to roll back Start/Stop Technology

[DuraYuk]

I think it's stupid too. Yes fuel injection won as it should have. It's a performance upgrade in typical daily drivers of today. I don't see where ass is gonna help performance. Mileage, maybe. I also hate tire pressure sensors but guess we're stuck with that too

Than turn it off? Vehicles burn gas idling. Auto start stop saves fuel. And it's seamless in operation. I dont know of any modern system that uses the accelerator to wake up. It shuts off when brakes are depressed and wakes up as soon as you take your foot off the brake.

Again people are complaining about things they dont fully comprehend.

And if it annoys you they all have a switch to turn it off.

Whoop whoop.

fuel injection is awesome, auto start/stop sucks, durayuk is clueless

I’ll leave it at that

Auto start/stop saves a MINUTE amount of fuel. Not nearly enough to justify the extra development cost, additional wear and tear on whatever A.S.S is used. An engine running in motion is happy, fluids are circulating, electrical system is topped off and ready. HOW is shutting down everything, except the key electrical components a good thing? Yeah, just start the engine 1000's of time for no reason. Oil pressure, no oil pressure. Coolant flow, no coolant flow. Electrical systems in float mode, electrical systems in drain mode accompanied by multiple high amperage in-rush events to spin a starter.....

It's a pathetic attempt to save minimal fossil fuels for the "feel good, A.S.S. pats all around, we're saving the environment" club. Common sense says keep it simple. If the GOVT said that you need to sprint, then sit, then sprint, then sit.........forever, when walking or jogging would be more effective, what would you prefer? Which one would have less wear and tear over time?

I'm glad I don't have anything with that awful system. It should be eliminated. Lastly, since when did starting a vehicle in gear become a "good" idea? This is a product of narrow minded people grasping at straws to stay relevant.......then the rest of the sheep jumped on board too.

I see. This isn't about how things work. But 'oversight'. Nice word choice guys. Let's keep fighting science.

The systems are designed for it. Its not grandpas car with no other improvements running it. Oil pressure ? Doesn't drop to zero when it was just on then off. It has to bleed off. It doesnt. The electrical system is designed to sustain it and maintain charge. There's algorithms it doesn't always auto stop unless all parameters are met.

I get that you dont like it. Thats all you gotta say but dont make up bullet points that are easily disproven.


Thankfully we all have a choice.

The automatic start/stop function shuts off the engine when your car is idling. But just how much does this technology really save you on gas?

An increasing number of new cars are being equipped with stop-start systems that are designed to save fuel by shutting off the engine at stoplights. But do they work?

What did they call the last gimmick science that was supposed to be uber-cool gas save tech? Active fuel management...that went well! Right guys?

Does anyone driving a truck actually care if their mileage goes up by 0.37561 miles per gallon?
No, because if they did, they would drive like it. Maybe the five-under guy in the 98 Camry cares?

You can't force-engineer GREEN into products that inherently aren't. Just like you can't make low fat "Ice Cream" that actually tastes like ice cream does.

All you can do is optimize, and we have essentially optimized the ICE (Internal Combustion Engine, not ice cream). When that's not good enough, come up with a scheme to appease the green cult and get the Science People™ all revved up (pun intended). But all you're doing is putting off the inevitable.

Which is electrification.

P.S. You can trust me, because I actually do have an Environmental Science Bachelor's from a real university On second thought, that's not a reason to trust me at all...

I'll bet you're at least smart enough not to think "miniscule" means "non-existent".

We have one of those members who is incapable of connecting two thought bubbles into a consistent philosophy.

Best part of AFM is that is shares something critical with Auto stop/start :: it can be disabled and/or deleted

Good thing PPV’s have it deleted from factory

Wonder why

This was well said!

It works. It saves gas. Leave it on a switch like it is. Maybe give the option of turning it off permanently instead of pressing button everytime.
Vast majority of people benefit from it.

If we took a poll we might know what the “vast majority” of people on this forum think. My opinion is it’s useless and annoying.

Saving gas? I will check out your link to see. For most of us we didn’t buy these trucks for fuel economy. Less than 2 miles a gallon is pretty insignificant and you can get better than that by driving like a blue hair prius owner. Maybe if your normal commute is many minutes of stopping in traffic constantly. My experience with my 2024 Tahoe with Carbyte device that eliminates auto stop doesn’t show any difference in fuel economy in my experience. I don’t live in a big city and the stops at lights are usually less than 90 seconds.

Also the action of starting a V8 engine in gear doesn’t seem like a good idea and I think the physics and chemistry might show it takes more fuel to stop and start over a given period than just keeping the engine idiling. If there is any science on this I would like to see it before making any statement about significant difference in fuel economy.

Blue hair huh ? There it is folks.

I love how all this is based on what you feel and not what you know.
