I'm having odd, possibly ECU related problems with my 98 K11.
(NATS).
Can I swap the ECU between a 1.0 and 1.3?

» CMF MemberNo, NATS will not work if the ECU is swapped, the engine will not start.
What "odd" problems?

» CMF MemberECU light flashing when key is inserted, and not starting.
Exactly the same symptoms in fact as if a key with no transponder is used.
When it does this, turning off and on several dozen times (without trying to start) eventually clears it, and it stops flashing, and works again.
It does this rarely - once every several months.
To clarify - I mean to change the keys at the same time.
Doesn't the NATS identity of the car 'live' in the ECU?

» CMF MemberNATS identity is within the ECU, I had problems with my NATS. NATS was randomly immobilising my vehicle whilst driving.
I went from a 1 to a 1.3 engine, and the problem consisted. In the end my mate wired in a NON NATS ECU. NATS is still there but the ECU doesn't look for it so everything works fine!!
I don't know of anyone else running a NON NATS ECU on a NATS Micra!

» CMF MemberAny ideas how he wired in the ECU?
I think the best way to change the ECU is to take it to nissan and have the ECU reprogrammed to your keys..

» CMF MemberWhen it fails to start have you ever tried removing the key completely and reinserting it? Perhaps the reader is faulty.

» CMF MemberUnfortunately not.
I tried this - and it seemed to behave no differently from turning it off and back on. It still takes (when it's doing it) several dozen attempts to get it to work.
Also - the price on ebay for ECUs seems to be similar to the price that nissan'd want to register the key, and I'd need to buy a new key as I've only got one working one at the moment.
If I can find one on ebay/breakers with a couple of keys, that'd work.
