Programing CECU on 389 pete

Just replaced the cecu on a 2013 389 Pete . Looks as if it needs to be programmed as none of the gauge or dash works at all.. Which software is needed to program this?

Taking it to dealer is not necessarily an option as the engine is missing some parts...unless I can just take them the cecu unit and have it programmed that way?

Any help is appreciated

 

how do i get my hands on this sir? im guessing it just like evey other truck software. impossible to get and costs a fortune?

 

the entire dash and gauges is going haywire - constantly sweeping the speedo and rpm - abs codes constantly flickering on and off all gauges constantly sweeping for no reason... thought it may be wiring problem but noticed it only does it when the truck has been running for a couple hours.. like the computer is overheating and freaking out or internally is bad... deererunner97 provided a cecu he bought from dealership so i swapped out with that one...

anything else i should be looking at or diagnose first ?

 

thanks. what voltage would be considered overcharging? alternator never gets above 14.1.. now the voltage gauge in the truck dash is different story - the gauge usually reads at 12v but sometimes reads up to 13.5v or drops down to 9v - nothing is actually happening to the voltage, just the gauge moving constantly for an unknown reason... i put a new gauge on it to rule that out but it does the same on a different gauge...to me just seems to be something with the computer... i don't really know much about these multiplexed systems though
