understanding incal and xcal files

[Rawze]

First of all, if you want to make a backup of the old ecm onto your laptop .. the option is called "Upload".


Next.. if your looking to Write a file from your Laptop BACK TO THE ECM ... onto the truck .. it is called 'Download".


You were not very clear what you are trying to even do in your post there. It implies that maybe you have confused the 2 options.

===============
the next confusion you seem to have...

"Incal" files are simply the default blank factory files straight from the engine maker and nothing more. It is what the stealer#shi#t shoves into your ecm when you buy a new ecm. They have nothing to do with calterm or any kind of de-mandates, etc.

If you are copying the file from one ecm to another one.. it has absolutely nothing to do with the factory "incal" program files at all.

=========

-- For any engine newer than a CM870 ... All someone typically has to do is simply "Upload" the existing engine file out of the old ecm.. and then "Download" back it onto the new ecm. simple as that.
