Strange question time. Does anybody know if it's possible to use a computer attached to the obd port to simulate the cruise control switches therefor removing the requirement to retrofit it?

Yes. Somebody knows.

I doubt it

Seems like a waste of time and money, fitting cruise properly takes less than an hour.

the only reason i have asked is i already have a computer fitted to the car which is doing all the multimedia stuff. it currently is connected to the obd port with VCDS Running so i can have gauges etc on the screen in dash and i just wondered rather than retro fitting the cruise if i could just program the ecu to respond to a code from the pc 

Seems a very long way round to simply get cruise which as said can be fitted easily, also  having the cruise on the stalk has its advantages whilst its engaged.... when i put mine on i can speed up or slow down (depending on traffic) by simply keeping my finger on the button to slow... or increase speed, how would this be possible from the headunit... and your also taking your eye off the road a lot more if you could have a number of buttons on the unit to do this... keep it simple, fit the cruise that the car would of had if it were spec'd when new, i really use the cruise on my car and find it very easy to put on and take off and change speed whilst driving.

It would be one hell of a project along with a set of sensors for adaptive cruise control, maybe arduino based.

This interests me but I'm pretty sure you would need a stalk anyway to find the correct signals/ons and offs etc. How would you control this also? I'd hate to think what would happen if my cruise control got stuck and accelerated so I can imagine the problems you could face if the computer/arduino/pi crashed or sent the wrong signal!

Interestingly I had the thought the other day as I was pushing the rather clumsy cancel button, how better it would be if it was in my right hand on the door for example! Or on the roof! Or in the back seat allowing back-seat-driver's a bit of control for once!
