Title: 1.8T, A3 Fueling issues. Experts needed! Post by: ottosan on February 20, 2018, 01:24:53 PM Hello,
My current problem is that after turbo upgrade fueling looks very strange Is this a fuel Pump? Or oxygen sensor? Something else ? I hope somebody can help me to sort out strange behavior of my car. To the car: A3 2003 m.y 1.8t K04 turbo Saab red injectors p/n 0280150431. screen shots as well as CSV logs are attached. I wonder, if the fuel is not there should not EGT be high and ignition retarded? Thanks in Advance, Title: Re: 1.8T, A3 Fueling issues. Experts needed!

Definitely not safe to run. Also, you might want to taper your req boost. your turbo can't keep up. Title: Re: 1.8T, A3 Fueling issues. Experts needed! Post by: ottosan on February 21, 2018, 12:14:01 AM Thank your opinion Nyet,
As I wrote above if this is fuel supply related, than should not EGT be very high and ignition retarded? Title: Re: 1.8T, A3 Fueling issues. Experts needed!
