RX8Club.com - traction control problems

third motor been installed now and when i got it back my traction control light is on. wen i start the car up the light is off but once i hit over 20mph the yellow car wth swirves comes on. any suggestions? i did the battery off for 5 min reset, and the tach reset to no help. i called the dealer but they played dumb and said theat wen they test drove t after install the light was going on an they didnt kno why, hinting that is was a problem before it went in. i dislike my dealer and dont wanna pay them more than i have to an everytime i go in there its a fight so please any suggestions.
