If that is the case, why does the ECU have to be removed from the drivers wheel arch to be re mapped. I am no expert on this as you all may have gathered. So don't know who is correct, but I am leaning towards Streethawk as from this forum I think Olly is the top man.
I think I am going to tell them if they kick off I will settle what is owed on the car to clear the PCP. I will then start taking it to an Indy. I don't want the map to be reset.
Thanks for the replies. :)
My E350 goes in for a service next Saturday at M-B Northampton. I don't want them to know it has been re mapped as it is still on a PCP. This may sound stupid but will they do anything that would wipe the remap. The car is over 3 years old so don't think there would be any updates for the ECU...
