we started my dads car up to load it for vegas, and it wouldnt go over 4000. I hooked up the laptop and it said TCD alert. It is a 7530T box, the one that had no TC capabilities (traction control). you have to leave the ign on for 24 hrs to reset it unless you are at a national event and nhra can do it for you. They had no explanation for why it got set off, said it happens sometimes at start up if it kicks back and gives a false trigger reading. keep that in mind. they told me I could buy some new box for 800.00 and it wouldnt do that.
