Engine Problems!!! Need Help!!!

[eweppler]

Ok still waiting for my exhaust manifold to get here but i decided to check my CEL that is on all the time after a few seconds of running. I pulled up many error codes on it. The ones i caught for sure was 13, 25, and 14; there were other error codes as well but i was unable to have enough time today to sit there and figure it out. Could this possibly mean that the ECU is shot? I do have another ECU but its an eprom and i know its set up for a manual and mine is an automatic. Would it be bad if i hooked up the eprom one and started my talon?
