« on: April 25, 2006, 20:13:22 »
hi folks just moved up to a td5 110 from an ageing 200tdi
and considering upgrading the engine management especially as some claim improved fuel economy,just wondring what your experiences are
i.e do they work
    which is the best
    any adverse long trm effects
other things to consider are the vehicle is three and a half years old and covered 57k,and i dont expect to do much more than 5k per year

Knowing, quite well, the guys that did the development work for J E Engineering I'm pretty sure that their stuff works.

One of the guys that did their development work was flown out to Portugal by Bowler to sort out the mess that another "tuner" had made of one of tha Dakar Wildcats.

Don't bother with a plug in interupter box!!!.... tis just a bodge method.

Get a proper chip replacement or reflash (depending on year)...

Top of my list would be Allisport ( www.allisport.com ) , followed by Bell Services and JE Engineering.

That made me chuckle as I know him rather well too :wink: ....  he came back with a few nice pictures of the bowlers though.


Long term effects...

A chip/reflash will take a TD5 closer to the engine limits... but a good tune 'should' still be within them.  
As long as you adhere to correct servicing and look after it, you shouldn't have any problems.  I know of tuned 90's that have done 140,000 miles (the last 80,000 of them tweaked) without any problems.

My 110 was tuned using a plug in box from allisport and large intercooler - make it go like stink and worked really well, reliability was 100%, never had any problems and the engine had done over 115K when it was chipped @ 3 yrs old.

I'm considering remapping my 90, its only the cost thats holding me back as i've not herd or experienced problems that are actually due to remapping/chipping or increased performance mods.

Yep J E engineering definately.

A freind of mine has a 110 that J E tuned. It then got an air filter (ITG I think?) and an exhaust. However, the vehicle is used for towing up and down the motorway everyday and the exhaust soon got tiresome so off it came.

It puts out 205bhp and has a GKN overdrive. I recently brought the truck back from London for him and got carried away. I looked down to see how fast I was going before engaging the overdrive and was surprised to see that it was very fast (edited for lagal reasons!).

But that's only half the story - the torque is fantastic!

It's a 53 plate converted from new and done 108,000 miles. Mostly towing! So reliability is good.

The main downsides of the remapped ECU route :

You usually have to send the ECU away, so your vehicle will be off the road for a while

If you ever have problems with the vehicle, you can run into issues with getting diagnostic information from the vehicle

Warranty claims aren't much of an issue I am guessing due to the vehicle age, but that is another factor.


Plug-in solutions may not be perfect from a technical perspective, but they do have some advantages

Depends on the age of the vehicle, flash type (2002 onwards ish) can be done straight away.  Earlier types require the ECU to be socketed.  Anywhere decent will have slave ECU's.... so can do a straight swap.  (I know Allisport do)

Edited to say:
You may have meant this slightly differently...

A interupter box could be sent through the post,  but an ECU needs recoding to the alarm unit (injector codes aren't as important), so not a straight swap you could do at home... means visting the 'supplier' - but only takes 10 mins when your there.

Why's that??  All the chip/relfash does is alter the fuel map... and at times plays around with throttle progression.  Getting Info stored in the ECU is no different from a standard vehicle.

True... hence why you'd go to a reputable place... so in theory nothing will go wrong because of the new 'tune'

They also add fuel at the wrong time, thus messing up the timing and thus can cause more damage/wear and tear.

All the boxes do is confuse the signal, and allow the injector to inject fuel for longer.... but not at the right time.

Some of them will also cause the engine warning light to come on at times, and even make the engine revert to limp home mode.


With a good tune, a bigger intercooler and with the boost up a little bit (17psi is good  :wink: - though most of the interupter boxes don't like it when you do this... well the ECU doesn't - it gets too confused) you'll have quite acceptable performance.

If you mess with the ECU then you'll need a rolling road as you have done a few miles.

Not really, although all remaps/ecu work SHOULD be done on a rolling road 99.9% are not, proving its not essential.

Its an ideal world where they are all done like that and i dont even know of a landy tuning company that has a rolling road!!

Rolling roads aren't always the most acurate things in the world anyway....
However I know that Allisport and JE Engineering use rolling roads to test their tunes.

In all honesty, rolling roads aren't always the best things for developing new tunes.    They are though, a tool that should be used as 'part of' the development process.

No matter how good the rolling road, it will never fully simulate real life running.   Esp. when it comes to air flow.

Also, when it comes to altering throttle progression and setting smoke limits, it is much easier to do on the road, than on a rolling road.

Yes, assuming the supplier isn't a 3 hour drive away ;-)

Why ? Because they are funny old machines...  we've certainly encountered issues with Testbook on remapped vehicles.

Ho Ho Ho...  I'd have thought you would know Land Rover dealerships better than that !

Yep, I'm well aware of that... we sell both Dastek and Fearn units, and they do both have their pros and cons.   If you want to see how much power a Td5 can produce, you'll see a lot worse than Simon's challenge truck ;-)
