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!

I its 6 months old, then take it back to the dealer, get them to fix it under the warranty...

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

bombx3 · May 19, 2010

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.

the result is it now revs it tiny little big ends off ! brill 760 rpm 60gr
But still lost its power untill turbo kicks in ,any one know why ?

bombx3 · May 20, 2010

£92.70 from mattford landrover,but it now revs out
But its rubbish untill turbo comes in there is something else wrong ,nothing is showing on the nanocom
any ideas?

johnlad · May 20, 2010

have you cleaned your map sensor on the inlet manifold

bombx3 · May 20, 2010

i did that one the other day i found out it was a problem on some on elses thread.if the sensor was at fault would it show on the nanocom

jsbholden · May 20, 2010

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

bombx3 · May 20, 2010

do they break down much
can i test one?

jsbholden · May 21, 2010

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

bombx3 · May 21, 2010

do you no what it is called on the nanocom i cant see map sensor

jsbholden · May 21, 2010

From memory I think it's turbo presure. Figure is in kpa

bombx3 · May 21, 2010

ar 3450 206kpa
at 3000rpm it reads 196 kp
at 2062 120 kpa

bombx3 · May 21, 2010

780 rpm is 104 kpa

bombx3 · May 21, 2010

what i have seen is oil in the injector plug in bits but it hasnt tracked ,the britpart loom is only 10mts old
No nanocom fault shown

bombx3 · May 22, 2010

fitted new loom no good
thinking about breaking my relationship with landrover because its driving me mad!
