My ecm in my Z is a old stillen, I assume stage 3 upgraded. It was in there when I got the car along with the JWT intake and Borla CB. Since it has already been upgraded what will it cost to have it reprogrammed again. Basically what I dont understand is the "Process" of what they do to the ecm. What do they do? I understand the reprogram part but what is there something special done to the ecm the first time? Socketing? Is the first upgrade a major deal and then to have it reprogrammed again for further upgrades a diff price ect? If so what does it cost for the AIV delete and upgrade for 555 injectors? I hope this make some sorta of sense.. New learning curve for me.
