In maryland, if the car is not >= OBD2 (1995+ iirc) they sniff the exhaust while the car is on the dyno. If the car is > OBD2, they usually just plug it in and pull the codes (no dyno run). When I had my RX7, I used to fail the tests with the stock ECU for being too rich. After the megasquirt was installed (only change I made to the car), I passed on the first try. They never checked to see if my ECU was stock, only if I had a complete emissions control system installed. Sudhir
