Ecm swap

[Perro903]

Apologies for the late response, been ill. I did download the ecm on calterm and did the image/template on insite. The only 2 codes I'm getting is spn 639 fmi 12 and spn 103 fmi 12. The 639 I'm assuming has to fo with transmission since the old ecm had the ADEPT.tech. The turbo speed i thought was bad because of the turbo speed was bouncing around and engine was off, ran new wire from speed sensor to ecm and reading erratic signals On the dish computer. could the ecm be reprogrammed to adapt to the new motor or does the internals have to be redone in the ecm? ive never opened up an ecm sp dont knowmif they are all the same as far as to the components or the programming is what differentiates them.
