im putting ym p1 back to std to p/x and am taking out my old tek3'ed ecu to sell, and replacing it with a std ecu from another p1
is it just a case of swapping them straight over??

Or is there anything else i need to do?
is it best to do with the battery disconnected??

any help appreciated

 

I didnt do anything extra when i swapped mine. just unplugged and reattached the exchange one (my2000)

p.s. u could disconnect the battery for extra safety....
