Hi bro
I have the same need of disabling lambda on 402 dme
I can’t change any idle and POT values online - have a feeling that lambda overrides my input

I found something on page 5 about lambda
We should put 0 to four or five lambda addresses, then ECU will ignore lambda and refer to fuel maps
UPDATE: I can find 2 HEX addresses and only, I can’t see other three in my bin, WTF?

Tried disabling all lambda adaptation tables using winols. Car turns off after a fraction of a second . Did anyone have this issue?

After trying for a long time I noticed that lambda adaptation can only change 5%in 402 so disabling it isn't that important
