no sure about other cars but my MYVI has it....there is definately delay about 1-2 seconds before your car start to move vs eco-idle turned off.
When crossing, we want to move as soon as we step on the gas...not 1-2 seconds delay.

I'm wondering - isnt it pretty much instantaneous? Have there been cases of more accidents due to one using an eco-idle engine turned on out of curiousity?

actually in long run, might cost more because engine restart more often. Imagine at every traffic or junction stops, the engine need to restart everytime if the eco-idle kicks in.
thats what i think...

Retirees are trying to save on expenses by using as little resources as possible.

Turning off the Eco-Idle function will allow their battery to last much longer than if the function was turned on.

ah i see. sorry mine old car dun have such tech so didnt know its that bad for local cars..does sound in long run might do more harm than good to the car engine keep restarting like that..

Eco-Idle help to save fuel. TS want to turn it off.

Local car. Perodua Bezza. The delay is not much different like when you're pressing the gas to accelerate faster on automatic transmission on normal car. Not instantaneous but not too long either.

As for the fuel save part, it does save a bit of fuel in exchange for a higher battery performance needed. That means battery price is more expensive. But not by much. Around RM100 more than normal batteries.

I would say if you drive daily and always stuck in the jam, the fuel saving is more than the extra price on the battery for every 1-1.5 year.

I second this. I had something similar on my Mazda 6 (I-Stop), it is very annoyingly dangerous when the engine stopped when you're at junction or about to enter the roundabout.
Although it takes a second, it could be a second too late for the window of opportunity provided.
I've disabled it via the obd.
Now I don't have to press the disable button everytime I start the car.
Pros: my car battery & starter last longer.
Cons: my car consumes more fuel?

I once saw a Myvi performing reverse parking at the mall. When the driver stop to shift into reverse gear, the idle stop kicked in and the engine died, then promptly restart as the driver starts to reverse into the parking bay.

One of the most idiotic thing I've seen a car do.

AGM batteries altho expensive, they should last you very long. The longest I have seen before was 8 years (i'm working at a battery shop). To me, 1k for 8 years is quite good, comparing to the 300-400 bid batteries (DIN sizes) that you have to replace every 2-3 years.
Just that you paid it upfront loh

Bro., it is good to hear from you again. I had no idea about steering angle on smarter designs and it is good to learn something new everyday. 😊

Yeah I've heard of Serena system but I havent had the chance to work on and with such a vehicle yet. 😦

Can lah. Next time u need replacement u PM me. I quote our price.

Is there a way to program the ECU to permanently disable the auto start/stop feature ?

Get rid of this annoying crap once and for all.
