I have a Sportsman unit installed on my dragster. Currently it is installed in the nose. Periodically even though the card is in the slot it will popup on the IQ3 dash the word "Card" which means the card is not in there. Believe me the card is in there. I have tried a couple different cards. The card is not the problem. Its like a little vibration will make this issue arise. This weekend I drove the car to the lanes and everything was good. When I got strapped in & started the car the word "card" showed up. Very annoying since I was trying to get data on a new converter. Any advice on what this issue could be & how to fix it. This sportsman unit is approx 5-6 years old
