Ah, i've already got the remote ignition up and running over wifi, it works fine?
But the way it's set up is in the arduino program it simply has a delay for the ignition relay to be on for, which is 1200ms
but like i said, for cold mornings, sometimes 1200ms isn't long enough.
i need some way of the arduino sensing that the car is running, and thus switching off the ignition relay
It's an old hilux with no immobilisation or anything so it's a piece of piss to get the starting side of it done.
