My 04 Coupe deploys at exactly 57 and goes away at 36. Increasing or decreasing your speed in increments using your cruise control will give you an exact number. "Please be very careful if you are going to try this."

How far can you move the limits? Is this sequence in any of the manuals?
Thanks,

63 mph average though to me it seems that slow acceleration = 65 mph and faster acceleration = 61 mph as if the car was anticipating. I guess no one has a modifyed relay or ECU to delay the spoiler - I would sure like it to deploy at 70+ - don't care for the attention at 63mph. May have to go the manual toggle switch modification
