So it would still be worth buying at the right price and getting it unlocked ?
I thought the immobiliser was separate , being part of the ignition barrel so it wouldn't matter what ecu you had in there ?
Slightly off topic , would a 172 ecu be ok in a 182 ? Could it be mapped to a grp n for a 182 ??
Yep possibly I don't trust any mapper who say 12hp from a NA engine that takes a 182 to close on 200hp which no one has done without other big bits.
The imobiliser is in three parts or so part.
When you put the key in the imobiliser ring round where the key goes (regular failure point) picks up the signal and tells the UCH under the dash the code it told the UCH then chats to the ECU to agree that the three codes the key the UCH and the ECU have are the same before the ECU can open.
Not sure on the 172 ECU the 182 has a 3rd generation ECU imbiliser built in so I'd think not but the wirings the same.
Group N means nothing though my cars Group N spec its a name for parts which are allowed to be used in group N racing ie showroom spec they cna have slight chanages to account for the fact that they have different exhausta and Induction for racing use but no amazing mapping realy they can just amp a little more fuel.
