RoverRon's Code Reader and MAF reading

ikorodu · 8th February 2008, 05:39

Hello all,

I have just got one of ron's CR1 code readers. Whilst I have no error code I was looking at the live data function yesterday with lists 'MAF(lb/min)' which I assume is the reading derived from the mass air flow meter.

The thing is this value never changed with speed, I would have thought it would have increased with speed? It was only on a very short (2 mile) journey that this was being monitored.

Does this seed normal? Or should I be replacing my MAF?

Any help appreaciated

Rob

Tried again tonight and still get a fixed MAF value of 10.11 lb/min. I've either got knackered code reader or MAF. Can any one confirm that thsi figure should be changing?

Thanks

Chances are it is not actually displaying the maf data but something else
You mission should you choose to accept it is work out what that is

interestingly, U381 on a 2.0HDi MAF live data has readings from 0.7lb/min-ish idle up to about 8.0 going along. Not sure what this means, but I'm happy
