Q4 ECU - IAW 4W6

[wrinx]

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)? :huhsign:

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.

I thing every model such fiat coupe or deltona evo2 with ignition coils will fit normally

[wrinx]

Thanks guys...anyone able to confirm, I'd hate to spend my hard earned on a possibility?

Struggling to find someone to repair mine :(

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

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

wrinx : im currently braking mine Q4 (rebuild), so if u need ECU to test i can post it to you to try with mine ecu to see if it works. But ull need to pay for post fee to your place and back to mine :)

[wrinx]

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.

[wrinx]

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...

Is the ECU code 4W6 or 4WG???

I'm seeing references to both and my sticker isn't clear :?

wrinx

If I had to place a bet on it, i'd go with 4WG

[wrinx]

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

Found this pdf for the Integrale Evo 2, claims that is uses an IAW 4WG ecu.

[wrinx]

I've cleaned the sticker up a bit and taken a picture...looks like a "6" to me :?

It does indeed, page 10.

But then again, I've just spotted this for sale on German ebay: IAW 4W6 (http://cgi.ebay.fr/Steuergerat-Motor-Alfa-Romeo-155-Q4-IAW-4W6-NEU--/110476804219?pt=DE_Autoteile&hash=item19b8ee407b#ht_500wt_817)

So it looks like the ECU is an IAW 4W6

[wrinx]

How much!!!! :huhsign::rofl::E

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.
