The Omron G5V-2-H-DC12 ought to do nicely, Digikey P/N Z771-ND for $3.22 each. See http://search.digikey.com/scripts/Dk...l&name=Z771-ND.

Adapting it to your reference circuit is then trivial.

Do a digikey parts list for the forum. These can be made for much less but I was doing with local parts that anyone can purchase right away the day they want to do it. You could do one for half the price on-line which some people might want to do.

Someone needs to start making these. I get requests all the time but turn them down due to the time involved. I get emails weekly concerning these simulators for all kinds of cars and they work on anything with an air-pump. They can be adapted to wide-band with a little tweak of the voltage sent to the DME or ECM. Also you can use resistors instead or pots but I like the pots incase you get a car that need a voltage tweak to get the computer happy.

Best, John S
