This thread is really to discuss how to get the most out of Stop/Start. If you don't like it, there are other thread to b$tch about it.
So I'd appreciate it if this is not yet another advertisement thread for OBD port gadget to override the Stop/Stop setting. There is already a few threads discussing that tool.
I really don't mind the Auto Stop most of the time. But if I know I'm going to immediately start again. It's just a wasted cycle. But if I'm sitting at a very long light it does save gas. I also don't like it stopping if I just worked the engine hard and it needs to run to cool things down. Other than those two cases it works fine.
After having this for 1500 miles now I noticed a couple things I have not seen mentioned.
1) The Brake Pedal has more than one switch (or poles). The Auto Stop is NOT triggered on the brake light switch. The Auto Stop is at a different position on the Pedal. Now this could just be mechanical tolerances and some instances might Actuate the Brakes Light, Before, After or at the Same time as AutoStop.
To test this I turned on the Backup Camera (manual button) at night so I could see the brake lights come on easily. If I very slowly press the brake pedal, the Brake Light will come on and the Vehicle will stop (on Level surface). I can keep my foot here indefinitely and the engine will not stop. As soon as I push my foot a little further the Engine shuts down. This makes sense as they are probably independent circuits. It could be the same switch that cancels cruise control as well.
Another thing is, you do get braking before you hit that Auto Stop switch. Not a lot, but enough if you are on an incline or level surface. If you are on a decline there is not enough braking to hold the vehicle and keep engine running.
But knowing this I can decide on a case by case basis if I want it to stop the engine or not. You can brake as hard as you want. You just decide how far to let up if you want engine to stay running or not.
Again both the braking action and the trip point of each switch may vary vehicle to vehicle. I did have a quick look and it is one physical multipole switch. I was hoping it was separate so you could widen the gap a little more between braking and stopping motor (it's fairly narrow).
I've also noticed that sometimes there is like a 2 second delay with full braking before the engine stops. And other times it's immediate. I have not figured out what situation causes that difference in behavior.
It really does save gas. I was up in the high 20's AVG MPG after a long trip and pulled up to a light. I could see the MPG dropping continuously as I sat there waiting. And of course as soon as I pushed my foot the whole way the dropping immediately stopped. It's pretty cool to see that it isn't a complete waste.
