Help on how to display the 02 sensor signal

[LittleVinnie]

I am a newbie, and yes I have searched till I have a headache.

Yes, I am going to order a service manual. Is there a recommended place to get one?

My question is, under the diagnostic mode, can the 02 sensor signal be displayed.

Not having a manual [yet] Its hard to make heads or tails of the information found while

searching.

If it is possible, please help with the specific steps on how to display.

Thanks for your help!

ENJOY!

I have seen this link.

So you are telling me that #24 will display the 02 sensor return voltage ?

Does anyone know if this test can only be performed while in neutral?

Can you test drive and watch the 02 signal ?

IS it safe to say that #31 and #32 give you fuel trim numbers ?

Is there someone here that wants to sell their service repair book?

Answered my own question. Either I was doing something wrong, or you can not get live 02 sensor feedback readings.

I performed the mod this morning and added 7 to the co for 1,2,3,4,.

My bike has only 250 miles.

The CO increase by 7 across the board made a noticeable improvement!

After realizing that I was not going to get 02 sensor readings, I installed a jumper wire and volt meter to read the 02 sensor.

I did not have a chance to return the co back to stock numbers, but with the 7 increase recommended by you guys,

Cruising voltage was crosscounting as I would expect. ON acceleration, I was steadily holding .86 volts which should

average out to be about 12.8 air fuel ratio and the 02 sensor pegs lean on decel like it should.

On hard acceleration, or basically WOT, the 02 sensor was steady at .96 volts which should average out to be low 11's [ 11.2] air fuel ratio.

I say average air fuel ratio because we all know that a narrow band sensor is not accurate.

However I have been building and custom tuning performance cars since the late 80's.

I wlll return the co back to stock, and compare the numbers. I am very curious, because the improvement is very impressive.

More than I expected for such a simple mod with little explanation of what is going on.

ENJOY!
