UTEC broken??

UTEC broken??
was wondering if anyone had any advice for me. I bought a used utec a while back, just installed it today. The car starts and idles fine but the check engine, tcs off, and slip lights all come on and i can not rev past 2k rpm. I can communicate with it through hyperterminal. I tried a few different maps and even when i use the 0 map the problem remains. Any help would be appreciated.

Did you try and reflash the firmware on the UTEC? What version is shown in upper right? Last update was v2.8. Also, check the connection harnesses again to make sure they are all properly seated and locked in position. Beware - the reflash is a pain and took me about 6 attempts to find settings that worked. Baud rate - lower than TXS manual recommends, and I have to uncheck error checking. Otherwise, it would only get about 50% of load then crash.
