Nads, Can i point out i am no professional at cars, i am a computer man, which i am not very good at either lol. I went out for a drive and after it had warmed up plenty, I changed the setting to number 5 and still no fuel cut, But i know it was hitting fuel cut at setting number 6 before. @ 1.1 BAR 16 psi. The AFR gauge was showing the air and ratio at OPTIMAL level. Is this ok?
