Hi,

I think is FRMAX, FRMINKH, KFFRMIN, FRMINSLS in LRS module.

Why you need this? You must setup car without big stft corrections.

when running big injectors limit of 25% is quite a big step.... also lambda pid of 300cc injector cannot be same as pid of 1750cc injectors.

thanks for the maps, i am checking now!!

If you are off by more than 25% something is very very wrong, regardless of PID behavior.

my purpose is to lower the limit as the original 25% is quite high.
when running 1750cc injectors feedback limit of 10% is enough.
