as above im putting a my00 engine and ecu into my99 car do i need to reprogram keys for the ecu cheers quick reply needed thanks

audioscape

technically yes it would need to be reprogrammed. i beleive the code is held in the ecu.

ive swaped an ecu on a my00 uk car and no coding was needed

IF YOU REPLACE ECU WITH IMPORT IT DOES NOT HAVE ECU IMMOBILISER BUT IF YOU USE UK ECU IT WILL HAVE ECU IMMOBILISER AS STANDARD THROUGH THE CHIP IN THE KEY

All I can say is my uk car didnt. i sold/swapped my ecu(ecutek for standard). I had a my2000 and the other guy had a my99. We drove our cars to a meet swapped ecu's and both drove home again with no recoding needed. Both were uk cars. I know the later new age cars have a coded key

i cheated when i swapped ecu stuck ignition key from new ecu by induction loop worked to get me down to subaru.

scoobyboy

think the early cars had a seperate immobiliser ecu to the engine ecu which means you don't need to code the keys, later cars had them combined so you need to reprogram them

I OWN A 99 UK TURBO AND IT HAS THE CHIP IN THE BOTTOM SIDE OF THE KEY .. THEY ALL HAVE 2 IMMOBILISERS AS STANDARD 1 ON THE STANDARD SIGMA M30 ALARM AND 1 IN THE ECU. IF YOU SWAP ECUS FROM UK TURBO,S WITHOUT SWAPPING CHIPS IN KEY IT SHOULD NOT START UNLESS SOMEONE HAS HAD IT REMAPPED AND HAD IMMOBILISER DISCONNECTED ???? IF IT DOES NOT START YOU NEED THE CHIP FROM THE OTHER PERSONS KEY OR A COSTLY TRIP TO SUBARU )-:

Why you shouting?

Just speaking from experience here but

When I upgraded my standard MY99 UK Wagon to the Prodrive Performance Pack (PPP) I literally unplugged the ECU and plugged the new ECU in it's place.

You might ask why I did the PPP but that is because I was fortunate to obtain the full PPP kit but not through Subaru UK. Downside was that I had to do the work of installing it which with the ECU meant swapping the LHD box for a RHD one

My car also had the standard Sigma alarm/imobiliser.

I sold my MY99 standard ECU to a SN member with an MY00 car - again a straight swap in/out which took 15 mins in my garage.

I then sold the PPP ECU when I got an Ecutek'd MY99 one. Again, no problem with either myself or the person who bought my ECU.

Just my experience.

99/00 has no key immobiliser in the ecu..

Forrester and possibly legacy (memory not working fully) has an extra signal.. you get an Antenna error code if you use an Impreza ecu in a Forester and it won't run.. cuts out after a couple of seconds.. but Impreza to Impreza ecu swap assuming both ecu's uk or both jdm then there is no issue. . just plug in and go..

You can swap JDM to UK or visa versa but you need to swap cam and crank signal wires.. and becareful if sti due to engine and turbo differences but one would assume you are after an ecu with an ecutek licence in to get it mapped anyway.

Why you shouting? I dont own a my 99 or 00 but i used and as ive already said ive done the swap in person on a petrol station forecourt. So either my and the other guys car were one offs and or your wrong. Both had the sigma alarm and both cars worked just fine after the swap. There may well be a chip in the key but its not linked to the engine ecu.

you can't turn the immobiliser off remapping it either..

scoobyboy

it is linked to the engine ecu but all the engine ecu needs to see is the ok from the immobiliser ecu which reads the key, so if that reads the key wrong it tells the engine ecu not to start the car.

ive just had a simtek fitted to my terzo, and it wont start just keeps turning, would the standard immobilser fitted stop the car from starting?would the simtek need to be reprogrammed to my keys?

cheers

no..

map issue perhaps... speak to mapper..

Simon

impreza_terzo3_no257

you are the mapper simon lol.......fitted the new valve and same thing not firing.........i think its being picked up next week and taken to one of my customers from work!!!but in the mean time any ideas?

Jolly Green Monster

ahah.. the car that had sat for a few years and I got it to run and through MOt but couldn't test drive it..

not fully mapped as we couldn't drive it..

should start though

the idle valve on it that was dead would effect the idle settings I setup..

have you tried starting it with throttle open?

is it taxed and insured yet? I can come over and get it running again and we can then actuallty map it..
tbh the first time I came out to map it I didn't expect to find a car that wouldn't start and had had many hands all over it changing parts left right and centre
The broken off HT lead in the coilpack and damaged idles valve faulted play that day

Simon

impreza_terzo3_no257

ill be getting it taxed and insured this week simon, ill buzz you tomorrow and let you know the day just need to see if i can get a day off to meet up with you.

cheers
