As per title, am running a Ecos with a stage 3 setup. Been having a missfire lately after doing the conversion. Gone down the usual road of all ignition parts and sensors, gapping etc and still had it. A good firend of mine said what about the co2 adjustment on the back of the ecu?

I have tweaked this and seems to run a hell of a lot better. But what i want to know is what is the best setting for the co2 and how do i monitor it? Or know what to adjust it too ans its only a screw on the back of the ecu?

Any help guys?
