I had the alfa mot'd this morning. the lamb reading passed on both normal and fast idle, but the hydrocarbons were quite high at 0.6 and the pass limit is 0.3
im running my own maps based on the standard fiat coupe 194.04 map with only slightly modified fuel and idle speed maps.
I guess the high hydro carbons is related to the (lack of) cat, is there any way I an reduce these other than fitting the cat?
