6K2 Cupra - Lambda logs - do they look fine ?

[Radek]

Recently I found following error in ECU :
17536 - Fuel Trim: Bank 1 (Mult): System too Lean
P1128 - 35-00 - -

I'm suspecting pre-cat lambda fail , so I've logged group 001 and 032

group 032
first block 0%
second block -6,3%

group 001 lambda % vs RPM

On Ross-tech Wiki I found that specifications for normal operation are usually somewhere near +/- 10%.

Any comments ?

Its a narrowband car mate, so 032 logs are next to worthless.

Try logging 002 to see what figures your MAF is pulling.

MAF looks fine , it shows almost 140 g/s around 4000rpm.
I had no chance to log WOT up to the redline .
Chart below has been logged in traffic .
BTW What's load % ?

Help use help you, log it 4th gear, 1500 to redline anything else is pointless really except 3rd gear and id only do one block at a time.

Log 002,003,020,114,115 & 118.

Do one or two blocks maximum then post the results using the code button, graphs are hard work to look at.
