it's hard to give an exact number as the response of a narrow band sensor to AFR is like a switch.. at stoich it switches over from near 1V to near 0V. the actual voltage at which this occurs varies with sensor age and poisoning, and could be anywhere from 0.4 to 0.6V.. also depends on the earthing between sensor and ECU 
maybe you could set motor to a certain rpm.. like 2000 (no load) then richen up a a set rate (1 'thing' every 5 seconds) and see when the O2 response changes drastically. at that point, you've probably hit stoich. or you could compare it directly to a 5 gas analyser at a local mechanics using similar method?
