I've got one of the latest PSi3 graphical monitors (the ones with user tune, road dyno etc). I've set up the data pages how i want them but i've noticed both the air flow voltage and rear o2 sensor voltages read 0.00V all the time. Engine load, air flow (grams/sec) and air fuel ratio all read fine which use the voltages mentioned to calculate the data so i know the sensors aren't duff. I have also connected the laptop and logged these values with Enginuity and Ecu Explorer and they read values fine, vary as expected. So again i know for sure the sensors are ok. So why does the PSi3 read 0.00V .

I'll e-mail Simon and ask but he may be away or busy as he's not answering e-mails about another subject, so in the mean time anybody else notice this? The car is a MY06.

PS also my throttle reads 3% in the PSi3 when lifted completely off, the laptop programs read 0%....

Nobody got one then . Can't remember if my old LCD PSi3 read this correctly or not??

no MIne is always at about 3g/s. not volts

TPS in delta dash will read around 3% while Accelerator position reads at 0% - they get closer further up the range.

They are actually 2 separate sensors. The DBW ecu's interpret accelerator position to get to a throttle position depending on engine speed etc.

The MAF reading should definitely not be 0 though - I would have a work with PSI as it has to be a fault.

Of course. forgot there are two sensors you can view. So the PSi3 is looking at TPS while i was logging accel pos, hence the difference.

So your air flow value is stuck... mine varies as expected, its just the air flow voltage value that doesn't. E-mail now sent to PSi3.
