sensor is cold?

Setting aside the fact you shouldn't have the sensor in there when your first start the car, here's the procedure to check the hardware. Start there.

No sensor is heating up, and is out in free air . Cheers
I planned the hardware test forward today need some part for it.

Did the test, GND - pump- is 3,95v
pump - pump + is -729mv  ??? should be -4 +4mv

pump_pw_zero = 0A in config
tried to change it to 66 with vemstune but didnt succeed
i dont know the command for the terminal program bray
cheers

Its working boy this thing is fast  ;D

I remember having megatune 2.25 on my laptop
And used it to change pump_pw_zero. It was set at
0A sovjet is 10 in hexadecimal.
Some bloke on the forum had his set at 100 and Pump nernst cell at 132
Mine was set at 255. I set pump_pw_zero at 66 as recommemded by default
And volt reading changed to.-231mv, i set pump_pw_zero at 100 and.the reading
Was -0,01 mv. But reading was still crap changed, Pump nernst cell to 132 and it looked
Like a guage nicely jumping with slow solid movements. Set calibration to 214 and voila
Hovering around 20,9 20,8 low 21,0 high  :D

Little update figering vemstune out for ignition settings,
Pump_pw_zero can be set in
Base settings -> ecu calibration
