I am trying to get my o2 sensor voltages in datamaster after a data run.  I dont seem to be able to change any of the items in the item assignment drop down list.  Is there another way of getting these items up in the main list.  Or is there another way I have to set up datamaster to get the o2 readings?

Thanks  Fred

Thanks again Scotty.
Found it.

Hi Scotty,
Had the heads flowed and squish set up.
When doing my first VTune, bike ran ok some of the time, some of the time seemed a bit off. Taking off at the lights some times was an issue with fast poping. Sometimes giving it a fist full a lower speeds, also fast poping. By the way this issue existed before the heads were done.
I did a static data monitor of the DBW data to check the O2 sensors. The O2 sensor readings seem to be a problem. The front reading was around 900-1100mV and the rear reading seem to hover between 4000-5000mV. I let the bike idle for a while then looked at the monitor to see both voltages sitting around the 1000mV mark. They stayed at these levels till I turned the bike off. CLB set at around 650mV. No codes.

Maybe the back cylinder running too fat in hindsight and causing the poping?
Will try swapping front and rear sensors, although may not explain the high reading during

Just looking for any input you may have on this?
Thanks
Fred

Thanks

Aside from any possible leaks or a lazy sensor, when the bike was idleing seemingly normally, both sensors were giving readings around 1000mV or slightly above although the CLB was set at 650. I dont think that this is overly rich on a CL map.

Is it normal to expect the voltages to be this high at idle?

Thanks
