Disco 2 ECU from p10 same as p15?

As title, can you use a p10 ECU in a P15 engine?

Or are they not interchangeable?

You can do it only the other way around if you remap the 15P ECU to a 10P engine, 10P in a 15P will not work well

OK, cheers for that, I want to try and remap an ECU but don't want to do it with my own as I am happy with mine. It is just a case of seeing if I can do it and what difference it makes.

heard so many conflicting stories on remapping that I just want to try myself LOL.

I will be looking out for a p15 ECU.

Is there anyway of recognising from the outside which is which or do I have to trust the seller?

in a nutshell: 10P will have a MSB..... part number and 15P a NNN..... one, unless the NNN vas remapped
