Don't know what to suggest Fab - do you have a lambda meter yet?

Hi Fab, I am using a std. BCA with green spring at the moment, wideband lambda says "very good" (means AFR 14,0 at cruise and 12,5-11,8 at full throttle); you know my engine combo!
Any progress in your wideband project?

Hi fel's
I'll grind down mine slightly later,
the idea is to start with something approximative, as the wbo2 set up is not finished yet, and I'm only using a std afr sensor, which is not enough accurate.
the idea was to know what are using phase 2 cams guys . I'll start with something on the rich side as a bca one.
thanks

take time ,a fine emery paper, and a micro meter,
but you need a very good lambda meter
