Carworx mapping

[VtsTom]

Is it up to scratch?

Going to look at a saxo thats had a KMS ecu fitted and mapped by them.

AFR sits at 13.1: acording to the owner and the kms display.

Heard quite a few horror stories of badly overfueling engines mapped by them (sybez being one)

[jpsaxo]

it should be self correcting to around 14.7

[williamsvts]

they didnt do the mapping though did they?

[VtsTom]

Dont know, the lad owns it said he had it all fitted/mapped at Carworx, thats all he was told.

If its not self correcting Josh, what does that usualy mean?

Personally i'd ask the guy if he'd be happy for you to pay for it to go on to a rolling road. Find one you trust and beleive will give their actual opinion, and not one you want to hear. Explain to them why you are taking it there.

Ideally find somewhere thats dealt with the KMS before - that way they can see how its mapped, as well as get AFR readings etc from the rolling road.

The AFR should normally sit anywhere between 12.8 and 14.7, depending on load/rpm. There is a target AFR map on the KMS, and obviously dependant on whether the lambda correction is turned on. Also bare in mind that the ignition times need to be good as well as the fuel.
