Hello guys,

i need your help. I tested a lot but i didn`t find the error.
Please look at the attached logfile.

Details:
When i drive normal, arround 1000 to 3000 upm my target lambda should be 1 but it is jumping to a smaller value. I logged all variables i have for lambda. So i can find out whats wrong in LAMKO.
When i drive a long time with the cruise control, i get lambda 1. When i accelerate a little my lambda is jumping again to a smaller value than 1.

any idea will be welcome

no problem. Another log but same failure.

to analyse data, i only used excel....

Hi,

Do you know whether your lambda probe signal is oscillating? I guess that your lambda value is an average over this signal...
