Flash old ecm to new ECM

[Chamberpains]

I also am still in dire need to get the new ECM that i purchased flashed with my mommaburt cal. So if anyone has help here it would definitely be appreciated. I am too many years rusty and since i was on here and understood how to get this done myself. Plus im on the road in a towing companies parking lot. Away from most resources but the basics i carry in the truck
