MAF Flow Rates/Frequency

Does anyone know the expected flow rates on the TD5 MAF sensor and the associated output frequencies?

Testbook will show a healthy air flow sensor as 55 to 60 kg/hr at idle with no loads on the electrics, and 190 to 200 at 2000 rpm. I can't remember the tests off the vehicle - you'll have to check TOPIx.

Thanks, I've never used TOPIx but I'll give I a go. It's frustrating because all of the Bosch sensors have proper data sheets but there is no good data I can find on the VDO sensors.

If it helps, a new Genuine Part sensor and new VDO sensor read exactly the same with no difference in live data readings.
