can someone confirm to me the connections of the CO trimmer and the wires colors?
pin 1 {orange?} : connection to ecu's pin 9
pin 2 {black?} : ground - connection to ecu's pin 11
pin 3 {red?} : + 5 Volt - connection to ecu's pin 30.

CO trimmer on what?

what do you mean by 'on what'?
there is a 'CO CONTROL trimmer' on the Q4!

You'll have to explain some more....

I thought it shared the same P8 Ecu as the Evo 2 and Fiat Coupe, no?

Not sure on the ECU being shared but page 109 here says all about it: http://berlinasportivo.org/Technical/q4manual/Q4fuel.pdf

Evodelta,

this is the CO control trimmer

@AlfaJack
I need to know the color of the wires in the connector of this trimmer.
I believe that they are:
Pin 1 : orange
Pin 2 : purple-black {ground
Pin 3 : Grey-red {+5 Volt}
can someone confirm these colors?

Oh I see, thanks for the help guys, I never knew you could adjust the CO on your cars, you can't on my Evo 2, it has a IAW 4WG P8 Ecu the same as the Fiat Coupe, I thought yours would be the same.

Sorry for thread hijack, I'll shut up now. :smoke:

I will go and check and see if I can work anything out.

ED: I am told the ECUs installed on Q4s are:

IAW 4W6 616.00.102
IAW 4W6 616.00.103
IAW 4W6 616.00.104

Yes you are correct, only gives readings when the engine was running. Nothing on just ignition.

somewhere {in a backup cd} I have the codes from all the iaw installed on Q4 but I can not find this cd. If this will come in my hands I'll post the data.
Anyway, thanks for the effort Jack and wrinx.
