hello all:):D:rolleyes:,im just new on here,but i have a problem with my 2004 td4 freelander,big loss of power,& no rev,so i was reading on here,so i disconnected the air mass meter,and i had great power&throttle response,so i then fitted a new (intermotor) air mass meter,now i have no throttle responce but when it gets up in the revs(about 1500rpm)it goes fine & keeps going & pulls fine,till (4000rpm time for another gear):eek:!!!so can anyone help me out:confused:?from stand still very poor,will nearly stall in 1st gear if not dead level,& will stall engine when in reverse when cold on the flat surface,thanks for looking,,:)any help would be great.
 
Or you can fit a Pierberg MAF from Energy Tuning and a Ronbox, at a cost similar to a new Bosch one.

The Pieberg one needs the Ronbox to adjust the settings to make the MAF work properly.

Visit the Ronbox website for more info.
 
If you want to keep it standard but with the reliability of the Pierberg MAF you could do as I did and buy the new Pierberg 0.722684.11.0 MAF from the tuning diesels website I replaced the standard Bosch MAF with this one and it works great and a lot cheaper than buying a Synergy and MAF.
 
so is this aftermarket intermotor maf no good then,?can anyone explain the bad throttle responce, but good power up in the revs?if i leave the MAF disconnected,will this do any harm or cause any damage?thanks
 
Might be cheaper than a Ronbox, but not as fast- the Ronbox totally transforms the car to make it actually drivable and responsive to throttle inputs. Worth EVERY penny...
 
I've no doubt that the ronbox does make a big difference but not everyone wants the hassle with the insurance or can afford the difference in price.
I have found the power my FL has now is now pretty good and yesterday when driving in the yorkshire dales I found that I could get up most of the hills in 5th gear and occasionally 4th and 70mph+ on motorways if needed what more do I need.
 
can anyone explain the bad throttle responce, but good power up in the revs?

see the table at bottom of this page:

Maf sensor problems.

different mafs give different signal-to-ecu levels
depends on what the ecu is programmed to expect

if i leave the MAF disconnected,will this do any harm or cause any damage?

the answer might be somewhere on these pages

Tuning-diesels for affordable tuning modules.

i think it results in crap mpg .. i.e. overfuels somewhat
the ecu will use a built-in default map ..
given the ecu default will have worldwide operating conditions in mind
i.e. air temps etc .. which effect air-mass ..

be like when the air-intake-temp sensor be shorted or open circuit
the ecu uses a default temp of -5c ..
that .. in uk average temps will cause much overfueling
