Lets say I have an 08 manual ECM. (CM2000)
Lets say that I want to install the ECM on an 09 automatic truck that came with a CM2000.
Or vice versa... this is all hypothetical.
If I write an EFI Live read stock tune from an automatic to the manual ECM does it make it a complete auto ECM just like it came from the factory ? Or are there other things to change, ie it needs a reflash from the dealer to make it an automatic ECM ?
Thanks.
