Question

I recently purchased a second hand AE802 green label ECU from this BBS with the intention of having it remapped with a Tek 2 remap. I was then going to replace the standard ECU with the remapped ecu. This would give me the option to revert the car back to standard in the future should I need to.

My question is, will I have any problems with the new ECU not recognising the chip in-planned in my keys, immobilizing the car.

Ian

If you have a spare AE800 I would be interested in a purchase

But AFAIK if it is an EU Import, the immobilser should be ok

You'll have no problems with the Immobiliser.

assuming your car is new enough to have an immoblizer chip built into it (is the key big and chunky or really slim?) you will have to have all your ignition keys re coded to the ecu as it has to communicate directly with the key to disable the imobilzer. the people you brought it off should be able to tell you if your car needs re coding, or any subaru dealer.

My MY99 has had an AE800, AE802 and a PPP chip in, and all have been plug and play

Thanks again for all your replys my car is a MY00 so by the sounds of it I shouldn’t have any problems.

I've got an AE800 sitting in the cupboard, trouble is I have to put it back in once a year for the MOT. Link + MOT = Fail!

I can confirm there is no key reprogramming for MY99/00 cars - UK/Euro/STi/P1.

you should only need to reprogram if you buy new keys as it should remember the code for your existing keys.
