Title: STFT limit +/-25% and closed loop PID on MBOX
Post by: b16a on February 29, 2020, 03:19:58 AM
Hi,

does someone knows where is the stft limit of 25%?
also the PID of lambda controller!
both for MBOX

thanks

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.
