seem to recall something about the keys/imobilser needs re-programming or something like that?

i guess the alarm fob is something all on it's own or does something need to be done to this aswell?

or will all be fine if i just plug it in and drive off?:wonder:

Which ECU are you referring to and what model and year is the vehicle?

Engine management ECUs are matched to several other components to prevent vehicle theft by swapping components out of similar vehicles.
The Alarm ECU is matched to the Radio Keys, without programming your Radio Keys to a new Alarm ECU then you will not be able to switch the alarm from the Radio Keys.

:norty:thats why i changed everything in my uk97 for the P1 items/ engine/loom/dash etc etc....

current ECU is a ukMY99 with TEK2 remap. would change with same age PPP or std.

the alarm ecu, is that separate to the main one or part of it?

if an ECU swap means reprogramming the keys to the new ECU, is this a job that can be done myself or is it a dealer/alarm specialist jobbie?

spec'c'57- don't want to go THAT mad mad mate;):D

The alarm ECU is separate, so aslong as you don't touch that ,then no need to worry about the alarm or Radio Keys.

With regard to the Engine ECU though, this could be trickier.
I know on new age UK models that this would cause problems unless you have 3 other matched components.

On the 99MY though, the ignition key housing still holds a transponder chip, this is read by a receiver on the steering column and the engine ECU then acts as an additional immobilisation circuit.
The "maybe" here, is if the transponder chip in the keys is matched to the receiver ( in which case you will be ok), or matched to the engine ECU which I think will be more likely and cause you problems without the matched chips for the ECU that you intend to use.
However, it may be that the ECU you are intending to fit has had the immobilisation aspect de-programmed if its been upgraded (its not Thatcham approved - hence the need for a Cat 1) or may not even have the immobilisation feature if its a non UK engine ECU.

Unfortunately the ins and outs of the engine ECU, beyond standard UK ones, are an unkwnown for me.

cheers for the info mate:thumb: have a thread going in tech. on this and a guy with ukmy00 has swapped his std for PPP and had no problems:)

thanks again, been a great help:)

The MY99-00 ecu' have no part to play in the immobilser key recognition and you can swap ecu's around (UK-UK) without issue.

excellent:)thanks for clarifying that bob:thumb:
