Hi Dave !
that is a kind of car hard to do in the "dark" if you know what I mean !
I advice you get some knock device and AFR gauge , there allready exist MS42 tuning guide on web !
before check all vacuum pipes , and spark"s !
them advance inginicion tiil you start get knocking , them calibrate AFR

good luck

Well, i made an xdf for MS42 so that everyone can tune their cars themselfe. Problem is, there are several softwareversions and unfortunally yours is different to the one i made the xdf for. To be precise, your ecu uses 01100CA
and the xdf was written for 01100AD

When you?re using the xdf, your maps have offsets:

Nevertheless, if you want to use the xdf i can send you a virginized full-flash file which you can upload to your ecu in boot-mode and use the xdf.

Honestly i wouldn?t trust that guide to much ;) Its definately not usable at MS42 and i really doubt it works at MS41. Injection at part-throttle looks somewhat off, in my opinion.

Really?

Basic injection at MS42 (2L) looks like this:

Full-load injection correction looks like this:

How?s it possible to have a lambdamap with precision of 2, if the engine is equipped with narrowband lambda sensors that just can detect Lambda>1 and Lambda<1? How is that sensor possible to acchieve precision of 2? ;)

I may have a bad opinion, but that particular guide is definately lacking seriousness.
