its done every day. on most models though the stock parts stay in hooked up but are just shut down instead.
That option is largely closed. Not too long ago you could use a delete, but more and more that is simply locked out. Tuner kits for the last couple of years can no longer make significant changes to programming.

Included in the startup are test sequences for all the sensors.

Since nobody updated this thread, diesel is dead for now.

FCA has been caught not revealing all the AECDs in their emissions software Certificate of Conformance. That is a big violation and may cost FCA over $4 billion

This is a significant error and the EPA/CARB have taken FCA to court over this. Meanwhile sales of all US diesels are on hold.

Not necessarily this case. According to published reports there is a significant difference between the FCA issue and VW, in that the final product differed from the tested one, and the changes were not reported. The changes themselves were not necessarily illegal, but they were not documented which is a violation. Cummins has passed recert tests.

However there is probably little future for passenger car diesels. The features that made them appealing are long gone (simplicity, low maintenance) and they have become absurdly complex. At the same time, the EU market (which had provided the sales volume to justify development) is rapidly disappearing as diesels have rapidly fallen out of favor with the regulators there.
