Automatic starting

[AEH]

On Most modern cars, you just turn and release the key and your starter engages and stays engaged for a set time limit or until the car starts as opposed to the key keeping the starter solenoid engaged only when the key is in the start position. They also prevent the starter from engaging if the engine is running. I’m not exactly sure what you call that, but I’d like to try and duplicate it on my 69 Camaro. I’m close to starting my wiring and now would be a good time.

I believe any of the push button start modules could do it but I don’t want to eliminate my key or deal with RF id. I haven’t found anything yet I can modify. It could be done with a couple relays if there is an “engine running” signal to control a relay. I think most systems probably use a tach signal to the microprocessor to generate a run signal output that disengages the relay that controls the starter solenoid.

Has anyone done this or something similar? I feel like there is something off the shelf, I just haven’t found it. I plan to do remote entry but I’m not looking for remote start. And I’m still on the fence about an alarm system. I’m not sure they would prevent a theft but might wake me up in a hotel so I could. So if you have input on an alarm and/or remote entry system you like please let me know.

thanks
