Dan-O's WuNgUn Inspired Push Button Start

This is a new version of WuNgUnSVT's Push Button Start

I have most of the parts and the button is on the way.
Prices are shipped:
Fancy lighted push start button
DEI add-on starter module
Multi-function timer board
Passive RFID Remote security control

Here's the scenario:
  • Walk up to car
  • RFID fob in my pocket enables the dash start button
  • Press button once-->latch relays engage to power the car
  • Press button again-->starter module engages and starts the car
  • Press and hold the start button for 2 seconds to shut the car off
  • Multi-function timer engages, sends a ground to the hood pin input to shut down the starter module so no re-start will be attempted. The timer will also remove the power and ground to the latch relays as well so they can't 'bounce' back on
  • Release button-->timer restores the power to the latch relays

Because of the RFID disabling the starter button, an un-welcome button press will do nothing.

Wiring diagram and pics to come in the future.

Keep the input coming!
The more I work this out the easier the install will be.

Yea, I can't wait to see it done and functioning! Hell, will probably partake in it if it works well enough!

+1. Lately I've been on this electrical wagon where I'm fascinated by wiring type upgrades and tasks. From reading the other thread I can tell I still don't know my way around relays and timers well enough to be able to come up with a design on my own, but you've inspired me to learn more.

I'll be keeping a close eye on this thread, keep us updated!

I could almost make this plug and play.
If there were like 5 people interested, and it worked well 100% of the time, I could have 'em ready to go. They would just need a little soldering to interface it to your car.
Maybe $220 or so?

I know, I'm teasing.

OK,
I was looking for input from everyone but I came up with one thing on my own.
I'm thinking about a small push button for off.
I know it's intriguing to have one button to do everything, but I'm on the fence.
It just eliminates that one module that could fail and not let the car start.

Input?
Suggestions?

One sided conversation with myself: Dan-O--->
My wife has a good point; A 'kill' button that could accidentally be pressed while driving and shut the car off is a bad thing.
She says use the timer module to shut the car off after a 2 second hold of the one Start/Stop button.

Does anyone want to buy the one start switch I already bought?
I'll post pics later.

so if i read this correctly (please correct me if im wrong) your doing a push button start where you dont need the key in the ignition just the fob in your pocket?

thats pretty bomb if you get it working!

You are exactly right.
The FOB is passive like the OEM stuff.

As long as it's near the car the push to start will work.
If the fob is away from the receiver, the car won't start, heck the ignition won't even come on.

I will get it working, it's actually pretty straight forward.
