Remap regrets

[the evil twin]

can someone tell me if the dealerships can tell if your ecu has been remapped..i was under the impression they couldnt tell but someone has suggested they can...

AFAIK they can if for some reason they need to look.

For any factory updates all they do is just dump it into the ECU, no Dealer would be rrsed checking every vehicle thru the shop (not just Trols) so it would be every vehicle for non-factory remaps.

Chips are a different story... and for the record.. to answer the other Q, my guess is Yes
