another pierburg flow meter showed over 600. Now I have a bosch but I haven't checked yet
No problem then, sensor different to Bosch is not good for testing, ecu config is for Bosch, inclusive if other sensor is compatible it's well known that Pierbug reads are different, that 550-600 with Pierbug looks like false peaks due to different voltaje output.

I was hoping that 1200mBar was some sort of ‘full scale’ test mode, but you have 1107 as well so yes it must be a fault. Very strange fault though, why does the error in your first graph appear to be proportional to speed??


Does tapping the ecu change the reading?


ps: I tried mine (a 156 jtdm), there was no ram effect up to 70mph.
I'll check tommorow.

It may be that after the ECU reset it has an adaptation procedure and therefore such parameters ?? Is this the fault of the pierburg flow meter?
