hey guys and gals.. I have a 06 GSXR750 with a PCIII and was wondering how hard it is to install a air/fuel gauge.. I've seen some set ups but can't get a deffinate answer on what I need to do.. has anybody installed any other gauges on their bikes aswell?
You do not want to install an Autometer air-fuel ratio gauge on anything. The ECU/ECM reads resistance values that are produced by the O2 sensor, tying in a gauge that reads the resistance level will not only read the resistance level and give you a shitty A/F reading that is about as inaccurate as trying to guess your air fuel ratio by sniffing what's coming out of the tailpipe, but it will also change the reading that the ECU/ECM see and then it will try to adjust the pulse width to compensate, causing you readings to be even further off.
Buy the Dynojet one, there is a reason it costs more than the Autometer POS, it works. Dont get me wrong, Autometer make some of the best gauges in the world, I have run them in many of my cars, including an A/F gauge in my Camaro, until I found out it was throwing my left and right bank fuel readings off by about 15%.

U.S. versions of the K6 750 did not have a catalytic converter or O2 sensor so there is no closed loop operation with the ECU. Some have a "bung" in the pipe to install an O2 sensor (both of mine do) but I have heard some do not and one has to be welded in.
I can't comment on the Autometer. Never had or worked with one. Sounds interesting.
