Cant get O2 reading... :(

[gox]

I realy dont know what else to try,i tried so many configurations that i dont know what to do...at some time i even got AFR reading while O2 was ??.?,how is that possible?
last time i changed wbo2_nernstdc_target to 87 and i got reading of 0.45V all voltages are fine,like noted in Robs Manual.This is voltages that webshop sent me in my email,should i try to get this voltages?

The details of your Genboard:
Board_version=v3.3
Serial_nr=  1036
pump-= 4.15V
wbo2_pump_pw_zero=0x68
pump+= 4.31V
(C103=1nF, no D100)    <---- what is this?

this is my config:

> wbo2_abs_limit=E4
> wbo2_limit_maxt=A0
> wbo2_fallback=B0
> wbo2_retry_t=06
> wbo2_edgetime_corr=BA
> wbo2_edgetime_min=50
> wbo2_ri_target=00
> wbo2_nernstdc_target=7D
> wbo2_pump_pw_zero=66
> wbo2_calibration=A8 - i tried this one with larger value,no results
> wbo2_heater_pid_kp=46
> wbo2_heater_pid_ki=10
> wbo2_heater_pid_kd=1A
> wbo2_heater_pid_ilimit=80
> wbo2_pump_pid_kp=15
> wbo2_pump_pid_ki=4E
> wbo2_pump_pid_kd=00
> wbo2_pump_pid_ilimit=84
> wbo2_ri_confidence_scale=80

Heater is working,the sensor is little hot when i touch it after some time.While sensor was outside,not in exhaust,while i was assemblimg the unit i saw some readings,but now when everything is ready and i got all harness done and sensor in the place where stock sensor was,no readings.

Please help i`m going ceazy 
Thanx guys

First off, repeat the nerst_dc calibration with the resistors in the plug now that everything is in place.  While the thing is heating up, take a look at screen 7 (Manmlp07 then mll it a few times)  check that the heater value is increasing and that the heater is ON.  Make sure that you have a good 12v supply on the relevent pin.

Its worth checking your setup against the factory default ones: http://www.vems.co.uk/forum/index.php?topic=55.0 as I cant remember the right hex settings.

C103=1nF means that you have the Hall trigger setup, no D100 means that you're setup to use a powerflyback.

Ok,i`ll do the voltages again,should i try to get voltages from specification from webshop or from your user manual?
Heater value is increasing at some point,then i turns back to 3X and changes from time to time to 4X then to 34,35,3A,3E.... is that ok?
But how is possible that i had AFR reading at page2 after some time (mlp02),heater was on,so instead of geting O2 i get AFR reading,Engine off? Like this:

...
AFR:20,98    O2:??.?
AFR:9.09 (or ??.? this is target afr or?)

?

On more thing,map sensor offset,when engine is off map should show what pressure is outside right? I have from 990 to 1090mbar weather pressure,so map should show something like 100kPa?

Tnx Rob

Get the voltages from the user guide - you will have been given the pump_pw value with your webshop dispatch note, the nerst_dc is the one to calibrate - you'll expect to see values around 0x84

That heater value is too low, I expect to see it above Ax, check your target settings in MegaTune against the ones on the link I posted, I have seen an issue where a heater could not get above a low value and that was due to a hardware issue.

As for the MAP sensor offset, find the pressure in your area to calibrate it, I use the on-line report from my nearest airport.  When the pressure is 990mb I see 99.x on the display, when its upto 1090 then I'd expect to see 109.x

Problem solved!

Got all the voltages from the user guide (without sensor connected and heater on,i got O2% reading) then i connected the sensor and there was no O2 reading, wbo2_calibration was too high (A8) i never tryed to lower it i always went higher...then i tryed A1 and O2% showed! Now my wbo2_calibration is 68 (decimal) and i have 20.9
EGT calibrated too,thank you Rob!
