hi all,

had my car mapped but due to afew issue son the rollers we ran out of time to do the really light load stuff

the engine is a turbo 1.6 sigma engine, i have an issue when under really light load that it runs really rich.

the afr are fine when it get some boost generated but up to 10% throttle load its not ideal.

what i want to do is use the narrow band at the lower revs and light load area to sort this out, can any one help with the setup of this?

ive emailed the guys that did it and there going to get back to me next week sometime with what to change but would rather get on it earlier

thanks
