air flow meter

Nick T

Overdrive!
Not impressed with 110 TD5 engine. Ok on motorway but crap off road. Wont pull at low revs, seems like lag/time delay. Maybe it's just me? Anyway garage has give me a K&N filter and an air flow meter to try, although he said he really didn't think air flow meter was needed. My question is, do they work and has anyone fit one, do they make a difference. I am aslo only getting 22mpg:(

Try unplugging the air flow meter and go for a drive...

K&N and other similar air filters (personally I like ITG filters - and can supply them;) ) do make a difference, but it isn't going to be huge....

Has the garage plugged your 110 into a diagnostic computer and actually checked whether the AFM is working or not?? - or are they just clutching at straws?

The other fault might be that the EGR valve has failed, which can easily be blanked! - plates are avalible from quite a few places, including EBay.

Really you need to have you 110 plugged into a diagnostic computer, and check that everything is working correctly.

If you wanted to drive down to the midlands (100 miles ish or pay my fuel to come to you) I could have a look for you. If everything does check out ok, and you just need better performance then I could also remap ECU for you too!!! (a proper remap/chip - not a silly plug in box)

Fit new AFM this morn, immediate difference. Didn't feel like I was going to stall it when setting off. Miises went out in it, she noticed without me telling her about changes. How much for a re-map?

I really don't like the TD5 compared to 200TDi.:(
 
It can't be right if you almost stall when set off :/

The Td5 engine characteristics are completely different to the previous engines. Many people say that they find the Td5 gutless compared to the TDi engines, but from what I understand the Td5 has to simply be driven different. You need more rpms to get the performance out of it, where as the performance off-road on the TDi is right at a low point in the rev range.

Doesn't the Td5 have a far greater redline in the rev range compared to the TDi too?

Hi Nick, I was experiencing the same problem as you with my TD5. I asked Porny from the forum to drive over to check my TD5. His Rovacom Diagnostic setup found the AFM problem immediately.

I ordered a Genuine one, popped it in = MPG right back on the money....however, he did let me try his ECU chip during the meet up which resulted in me buying it a week after trial!!!! Absolutely superb. How does your 110 drive now? If DEFINATELY give porny's a try, especially with all that 110 weight. ;)

You wont regret it. :)

Rich,

Have you ever driven a Td5??... or are you just copying stuff you've read on other posts? ;) :rolleyes:

A Td5 is very different to a 200 or a 300Tdi, and is miles ahead with regards to driveability and control.
It is true that you have to drive a Td5 differently, but at the same time a Td5 will let you get away with a lot more than a Tdi.

With a Td5, most people find it's easier to get the clutch to the biting point - so the car begins to move - before applying any throttle.

What tends to happen if you plant the throttle is that it sits there for a fraction of a second thinking about it... but if the car is already moving you get a better reaction.... or hold the revs to about 2000rpm and come off the clutch quickly and you'll rocket away!!

A Td5 is much more 'car like' in the way the engine responds.

As for low speed off road, a Td5 has 'anti stall' built in... driven correctly you will be able to drive around without even using the throttle pedal... and a quick stab of the throttle will see you quickly accelerate... esp. in low range - as selecting low range automatically remaps the throttle.

James,

Your cheques in the post :D ;)

How much should the AFM cost?

It really does drive better, only had 2.5 pet and 200 Tdi before. Here is me slating Td5 for all it's worth and it wasn't running right:eek: different beast now! Is a re-map the way to go? Will it save me money on fuel?:rolleyes: Just had a bad month with bills and my customers not paying on time (usuall ****e) is a re-map an extravagance or do I really need it? Someone talk me into it:D

Depends where you go, but anything between £55 and £80... can't remember the LR main dealer price, but don't remember them being that expensive.

A remapped TD5...

Depends how you drive, if you drive it at exactly the same speeds, and in the same style etc etc as you do now then the mpg will not be any worse...
And in theory(ish) it will improve slightly as you will have more power/torque available - so at times will be able to pull a higher gear. In all honesty, the latter is more noticeable on a petrol car, but you should notice some improvement.
Most of the difference comes from the fact you won't be thrashing it to get it to go...

If you make use of the extra performance, then MPG will suffer.... as to get more performance you need to put more diesel in.

So MPG comes down to how you drive it (most people do notice an improvement in mpg though)


Remap wise... go for it ;)
You will definitely notice an improvement in the way your Defender drives!!


If I was to remap your car....
I'd happily give you a money back guarantee bar any incurred costs - i.e. fuel/time - if your weren't happy, and simply put your car back to standard... not that I've ever needed to.

What year is your Defender??

2001 on an X plate, ex BT, 42K miles. I am hoping to keep this vehicle for a long time!:)

Hi Nick,

Our mindset and TD5's are nearly the same. Mines near 40k, AFM died...and replaced, I alwo want to keep mine for a long time too! :D

Basically I backtracked through lro mag to 2003 defender shoot out. All about remapping. Could never afford the £550 most tuners ask for remapping so I left it.

I bumped into Porny on here who let me try his tune.
Honestly, I have never looked back.

I dont thrash my defender at all, never have, never will. Ask Porny, during the testing I wouldnt go over 3,500 rpm without sweating;)

My MPG has increased, only slightly and I get all the luxury that his chip has to offer.

- On hills theres no need to be changing down and oing through the motions. I just leave it in 5th and up it goes. Its almost a sensation like theres a giant hand pushing your 90 forward. Not aggressively, not with loads of smoke, just smooth power delivery.

- However, if you drive your landy hard then its as the saying goes "you dont get owt for nowt" as we say in yorkshire. More pedal = more fuel

I increase my MPG by letting the newly found increase in torque do the work for me.

- To comfortably pootle around town etc at 30mph in 5th
- To add flexibility to my 90
- To improve the pulling capability when Ive got the trailer and roof tent on etc etc
- To relase the power my landy can safely tap into as I service it and look after it well.

I have added a larger intercooler to lower EGT temperatures in the chambers to add even more power and lower temps.

If you ask Porny he'll fill you in fully on how the tune works, why its safe and keeps within the standard TD5's engine paramaters. (i.e. it wont push the engine to do anything it cant handle outside safe working limits)

- To try it is all you can do. You dont know what your missing.

Let me know how you get on. :)

I bumped into Porny on here who let me try his tune, and man is it a good one.

Honestly, I have never looked back. I once gave a plug in box a ry at a show and wasnt convinced. Plus I saw black smoke so I was deterred.

I dont thrash my defender at all, never have, never will. Ask Porny, during the on road testing with the rovacom I wouldnt go over 3,500 rpm without sweating;) Its not my style, therefore not going to do anything to dammage my precious TD5! LOL

My MPG has increased and decreased depending on my mood. Bad moods = lower mpg. But even then only slightly 26 lowest and thats LR stated standard. I get all the luxury that his chip has to offer even on 26 mpg days.

WHY proper remap?

- On hills theres no need to be changing down and oing through the motions. I just leave it in 5th and up it goes. Its almost a sensation like theres a giant hand pushing your 90 forward. Not aggressively, not with loads of smoke, just smooth power delivery.

- To add flexibility to my 90
- To improve the pulling capability when Ive got the trailer and roof tent on etc etc
- To relase the power my landy can safely tap into as I service it and look after it well.
- To have that power at the ready. A few times Ive been in a hairy situation on the M1 getting sandwiched between Articulated vehicles with ehr roof tent on, blipped the accellerator and...woosh, away.

I have added a larger intercooler to lower EGT temperatures in the chambers to add even more power and lower temps.

If you ask Porny he'll fill you in fully on how the tune works, why its safe and keeps within the standard TD5's engine paramaters. (i.e. it wont push the engine to do anything it cant handle outside safe working limits)

- To try it is all you can do. You dont know what your missing if you keeping your landy for a long time, enjoy it, were only here once.

Well, you asked to be convinced!

Let me know how you get on. :)
