GIAC FXK04 (Hammer)

Can we get an official number, or range, of where our fuel trims should be sitting at if the car is running at its prime?

I realize it varies from car to car but I just want a general range so I know where I stand.

Thanks

Also, aggressive k04ers feel free to post your fuel trims just for the record.

Thanks.

Can ambient temperature affect the fuel trim?

Yes since that effects your maf g/s readings, IAT's and how your spark plugs are effected. Any thing that has any effect on your maf or 02 sensor readings will change your fuel trim readings. The fuel trim readings just need to be with in a spec since they are just how much the ECU is adjusting for idle/part throttle, the most important thing is that your WOT readings are where they should be.
