a/f meter

[horndog]

hi guys im considering buying an a/f meter for my bike. not sure if i want data logging or not but i definatley want an a/f gauge. wat brand is good value? i know of innovative which is supposed to be good then theres the wideband commander from dyno jet which i only heard of when i found it on there site. any others out there that arent to expensive? cheers guys

If you want to be able to use the a/f meter to its fullest potential e.g. Changing fuel maps, you really need to have the data logging facility. The guage is ok but honestly I have taken mine off now as it is a bit hard to keep an eye on it when you are giving it the berries. At the most I would recomend a warning light output if the condition gets too lean otherwise data log it and analyse it later on a computer.

Better to look at the data in text form, the wideband commander comes with a pretty rolling graph but it does not help at all if are trying to remap the fuel. The wideband can export the data out to an excel spreadsheet where it can be manipulated and grouped to average your results by rpm and throttle position then make your fuel map changes based on the average. That has worked well for me.

See attached image, I got my previous bike 2003 R1 running beatifully on 12.8 A/F ratio for the 1/4 mile. The lean spikes are the quick shifter. I dropped about 2 tenths off my time by gettting the A/F right.
