I have lost a bit of low end power
I have read loads on this site about the maf and am totaly confused
Mine is 6mts old and gives no nanocom faults it says on 740rpm 40gm
so i disconected the plug and it pulls smoother and a bit more power, is my maf broke again!

patten part maf's are prone to failing and giving false info to the ecu combine that with Britpart and your asking for trouble, buy a genuinne maf about £75 should solve the problem

thanks for that .Britpart should be hanged and tortured for selling substandard goods
£75 for another maf is quite a shock !

If it's lasted 6 months it's done well

Should be reading about 60 if I remember correctly. Mine was also reading around 40 and felt flat. An OE one got it sorted.

Poss not. it could be giving a lower reading. would only reg on nanocom as a fault code if the sensor packed up and caused the ECU to use a default value

You need to colect live data from nanocom, ideally under load. Find a long hill and drive up it with revs about 2500-3000rpm. Should be getting a Reading of about 220 from the map sensor
