    Default Q4 ECU - IAW 4W6

    Is it shared with any other models?

    I'd have thought the Integrale and Coupe 16v but the Coupe has a different number....IAW 4WF.

    Can it be used on a Q4 (after removing the code)?

    No Idea if you can use the IAW 4WF, Maxiboost is pretty upto speed on all things ECU related. You might want to get in touch with him to see what he says.

    Found somewhere who can fix it, most places wouldn't touch it

    Think I've also found somewhere that has a brand new one on the shelf!

    Maybe this could be helpful. A friend of mine with a deltona had a problem and we thought that it was from ecu. For testing ecu we plug it to my car (Q4) and the car was working fine but with check light on. We didn't search why the check light was on because we want to see if the ecu was fine but the ecu is working to our car. Same the fiat coupe 16vt with ignition coils

    Thanks, appreciate the offer.

    I'll get mine checked out as it's obviously broken, but if it's still not right I might be in touch

    Would that be Mangoletsi by any chance? They always seem to have a few Q4 parts squirreled away.

    No, it was just one of the ECU repair companies, they were going to check and get back to me but haven't, so perhaps not...

    Me too! Particularly considering the previous code for a Fiat Coupe is 4WF!

    But then again, I've just spotted this for sale on German ebay: IAW 4W6

    So it looks like the ECU is an IAW 4W6

    It is German Ebay, everything on there is at a vastly inflated price. Makes me wish I had enough space to buy a second Q4 (where have they all gone these days?) and keep it as spares.
