I just got an SCT Xcal2 with a tune thats new. Problem is everytime i plug it into the car and try to download the tune it says "ECM powerup fail". If I take out the fuel pump fuse and the fan fuse, it waits awhile and then says "Powerup msg timeout" i think. Anyone that can help me, SCT is closed on the weekends and I'd love to get it goin tonight!!

 

Go over to the SCT support forums, their moderators usually answer any of mine questions in under 5 minutes.

 

Thanks I'll try that and see what i can do!
