Push Button Start - ideas?
Here at CF, we're blessed with a resident EE & small but dedicated support staff ... posts seem to imply superior knowledge of points to hei conversion, current & resistance, voltage drop, ignition module design etc. If it's not too pedestrian ... perhaps they'd solve this keyless pushbutton for Chris.
I love the stardrive unit - no question it is superior for overall one...and done rf keyless...etc. etc.
However, it is pricey, and I'm not 100% sold on the reliability of these as a stand alone - and how to overcome any issues if it were to fail out on the road. Also, I have never been one to be an early adopter of technology...so part of that is my personality.
What I did go with is the Watson hot-dot push button starter system. It is more "mechanical" in nature as it uses a series of relays instead of sealed electronics to do the trick. It routes through a single back glow push button. One push - car turns on, second push - it starts - third push, it stops.
Now...how do we secure the car you might ask? Going to do that through a standard keyless entry alarm system. I'm not even ready yet to select one - so I'll search the market once we are at that point to find one that best suits my needs for features I want the car to do...then wire it into the ignition.
Through secured wiring, the only way to start the car will be to disarm it - and on the standard security mode for most keyless systems it will re-arm every so often automatically so I can't get out of the car and forget to set it. Around the shop it will be in Valet and I'll have no need for keys.
It will run through the clutch, so my 5 year old can't accidentally start it.
Total cost was $130 for the hot dot, then I will spend anywhere from $100 - $250 on a an alarm rf system.
The picture below is just the button. The relay pack that latches and fires the ignition/starter is designed to direct wire and mount behind the dash.

that is the exact system i have. watsons has some nice stuff. the stardrive was too pricey for me too. i too am a little funny about new tech. i am still in the building phase of the car and am using a key right now to test everything but will be swapping over to the push button later. let me know when you find an alarm system that will fit the bill. i am interested in seeing what will work.
The Best of Corvette for Corvette Enthusiasts
If you have followed my 8.1 swap - you know I hit a snag as my ebay engine turned out to be a turd.
Anyway, heads are back on - hot cam installed - and now that the pushrods came today...I'll be banging it together and test starting.
With that said, I put the hot dot on the bench using a light to represent the igntion and a headlight motor to represent the starter solenoid.
All I can say is...it works...very well.
I have moved the assembly to the car and added an 80 amp relay to power up the accessory/ignition items.
Here is the deal. Because it is a MANUAL shift and I have a neutral clutch switch...this works very well. If I want to just turn on the power to play the radio, etc, I just don't push the clutch and push the button. That would normally engage the starter - but since the clutch isn't in, it only turns on the power. One more push and it all drops out.
To start, push in the clutch and hit the button, it runs....thenhit it again to kill it.
The clutch switch keeps my 5 year old son from jumping in and starting it.
I have many options on the alarm protection. Basically, I'll tie it to either the starter or main power coming into the switch. All of this will be deeply tucked in the dash, and should take just as long if not longer to "hot wire" than a stock switch and standard alarm.
I won't have a key at all - just a fob to unlock and lock (arm/disarm) the alarm and ignition.
Push the clutch in, and hold the switch down. The ignition locks and the starter spins. Once the engine is running you let go of the button - engine stays running and the light glows. When you want to kill it, push the button.
If I just want the ignition on, but not start the engine, I simply don't push the clutch in and push the button once to turn it all on, then once again to turn it off.
I am using the 80 amp relay to hold the accessory circuit (optional).
My alarm/keyless will unlock/lock the doors and turn on/off the starter defeat module. I can put it in on the starter, fuel pump, ignition - etc, (anything that I want to break when the alarm is set).
So...I will have a key fob only once this car is on the road.
Getting the button isn't the problem.

The thing is - this would still require a metal key to turn the ignition on...then a second step to push the button - not cool.
I would like to wire the keyless entry system to turn the ignition on so when you get in you just push the button - no metal key. - then ... how do you turn it off????
I'm sure somebody has done this - ideas?
It works like the new Vettes. There is no key. Once the key fob is within a predetermined distance from controller(drivers seat), you just push the button to start.
