Push button start hypermiling

[serialk11r]

I tested the button today on a car at a dealer (didn't buy), it works very very fast. I suppose it should, since all it's doing is toggling between the 3 settings that would normally be controlled by the key. I can live with pressing the button 3 times to cut the engine, and 2 presses to keep the radio alive after some modification.

Wasn't able to test the starter while rolling with the sales guy sitting next to me obviously. The starter has a half second delay between the button press and turning the engine, which kind of bothers me, but it's not a big deal I guess.

I assume this thing doesn't have an electric handbrake, mine kicks in if the engine is turned off or when a door is opened. Makes sense but EO(ff)C is out of the question with it.

Yup, manual handbrake, thank god. Yours automatically turns on? Ouch. The cars I've driven with electric handbrake don't do that.

This car has electric steering column lock that activates when the door is opened. The steering is surprisingly easy to use without assist, about as much effort as my MR2 with PS disabled despite having 500 extra pounds over the front axle.

The flywheel has a pretty standard amount of inertia, and the idle is very smooth for a 4 cylinder, so I'm pretty excited to experiment with lowering the idle. I believe it uses internal EGR via exhaust cam timing at low load, which will make tuning it for lean burn a little tricky (I hear the engine will stumble at just 17:1 AFR if you try this). Overall I'm pretty stoked to be tweaking a relatively state of the art engine. The engine braking effect is far far weaker than the 1ZZ-FE, the wonders of friction reduction and tuning

Yep. Toyota made the Subaru flat 4 work properly at last.

Your car is probably smart enough to know when it's moving at speed and not apply the handbrake in those (potentially dangerous) situations.

My car has a push start/stop button and although I don't use it as a killswitch, it can work as such very well and quite fast. Of course, it's not as fast as a killswitch because you need to press it for like 3 seconds in neutral or with the clutch fully depressed. When you start the engine back, you can just press the clutch and push the button and it starts very fast, even if you use it to turn off the engine at a red light. I don't know if it works this well with an automatic gearbox and/or handbrake, but with a manual gearbox it does the trick well. I even jumpstarted it and the car didn't make any strange thing, but sincerely I don't want to do it often, yet :P

The clutch might work as an interlock to prevent the car to go forward unintentionally while starting on gear. In an automatic it's usual to have the interlock at the shifter, starting only when it's either in Parking or Neutral.

Well good news, I decided to save some money and get an FRS instead since I got a pretty good deal, so no funky push button start to worry about.

But it was fun discussing this with y'all

Geez, wasting EVERYBODY'S time....
