Well, I'm still working out how to make the button both "START" & "STOP" the engine; I've got it narrowed down to the position of the clutch switch, i.e. whether it's released or depressed (to start the engine). I think I'm looking at three seperate relays, an IC 7400 series NAND gate and some miscellaneous discreet components to get it to work. If the damned button only said START, I'd be done by now

this issue can be figured out later for people who want to be serious... good luck with your modification , looking foward to seeing results.

I use to own a rsx. and I actually figured out how they stole it. thats a different case.. but back to this topic. sorry to thread jack a little bit.

that keyless idea works by putting a transponder key somewhat close to the switch.
example : My keys were thrown (don't ask) and the transponder key for my Maxima shattered to pieces. All that was left was the metal shaft that goes into the cylinder. So I called nissan with my Vin, they got the key code and cut me a new key. I just went and picked up the key since I couldn't drive my car and what do ya know, they cut it wrong or something. The key would go in the cylinder but would not turn to start the car. I have a bunch of friends at the Nissan dealership so one of them on lunch brought the scanner to me, we actually taped the old key to the new key and was able to scan it and use it that way. Made it hell to put in my pocket because I didn't want to seperate them but it worked until I got the right cut.
almost forgot.... SUPER cool idea with the start/stop button. I was hoping they would eventually include this option on the new Z. The keyless option that is. Would be very interested in seeing the final product and a little DIY on this. Keep up the nice work!!!!!

You know, this thing is going to progress to the point where it may be a little beyond a DIY simply because of the additional electronics involved. It may not be rocket science but it may be beyond the scope of what some people can do, especially if they have no soldering experience.

Unless your Key is BlueTooth and you dont have to put a key in the ignition then to me this is kind of Pointless. It looks nice, but you still have to turn the key making it silly IMHO.
Hopefully new Z's come with Bluetooth Keys and Push Start engines. That's 1 thing I love about my ex Lexus. You come close to the car the lights go on the doors unluck.

Progress.....
.....what progress? I'm sitting at my bench working on operational theory and how to lay it down on a PC board. Again, all of this to get the "STOP" functionality of the push button (and pulling my hair out)........

Look, sure when you step back and look at what I'm trying to do, it does seem a little silly; no matter. It's a challenge now and I think once it's done, the cool factor will be pretty high.
