This feels like one of those conversations that has massive satellite delay.

LKVDKNMN use this factor 40 precision 1
set to 1400-1500 rpm should be fine.

Think my 018J 360314 has the same issue.

I had 17705 and 17535 and the car runs like crap on cold stars until the lambda is hot.

First i thought is is because of the 600cc Bosch but now i chanced the LKVDKNMN.
I will report the other day when the car is cold.

you should check your injector scaling.

sooooo there is a loop of reving up and down again

What i did lately:
Changed my kfped to a linear (values like the column, 10, 20, 30, and so on)
Changed the lower values of KFZW/2 back to stock.

If i start my car and drive out of the parking lot WITHOUT touching the pedal at all, the revs start to hoover and i have to shut down the car to end it.

Maybe its related to kfmres/k, idk.

No file, no log at the moment. Just wanted to post my new problem.
