the wife and the freelander

hi all,my missus got this 55 plate td4 with 40000 on the clock,she had been moaning for ages about how it was driving.
got in it the other week and it was a bit of an old dog(the car)rough and slugish ect.
so i got me self on ebay and set to work.

egr blanking mod£30
k and n £40 at the door,bargin.
fully synthetic oil £40.
crankcase breather(modified)£38,ripped off from bmw.
oil and fuel filter and turbo filter£28(europarts)

picked a nice sunny day and away i went,off with the manifold and 2 cans of carb cleaner later,and all of the above done,drives like new,smooth through the gears and a tad more power.

got carried away with the results that i washed the bloody thing and got me heat gun on the black plastic bits(something about brining the silicone back to the surface and makes them like new.
so the question is,do i go for rons box of tricks or opt for the re mapp,,hmmmm
in my line of work these tuning boxes that trick the ecu have caused me some probs in the past,thats not to say that rons box would be trouble,lots of good feed back from here about then.
forgot to check what maf i have fitted in this,,,,a remapp is in the region of £280.
please make my mind up for me.
ps fitted the spring to the turbo acctuator,well worth doing,but it was a pain in the arse.
regards....

had my ron box for 3-4 weeks now love it, i would not drive without it.
the eco switch on dash is great for everyday use then flip it to red for full beans great fun look here

hope this help
i think remaps are good but you choose 1 ie max power or eco thats it ron box best of both world and you can sell it when you sell you freelander.
i think i made the right choice

thanks for your views,the remap guy did dis the tuning box,but he would do,he wants a sale.
he offered me a eco preformance map which was around 28 bhp increase,with a 10% fuel saving,,will take a look at rover rons site and go compare..

please make my mind up for me.

EndTuning - Tech - Tuning Boxes

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

i guess it depends how much you trust the fuel system overall ..
and how much extra you rekon the clutch/drive-train can take ..
and how much you can discipline yer right foot

as for fueling systems .. check out .. the 'helpful info' menu at:
Diesel Bob Tuning - Home

~~~~~~~~~

.. i think to make a truly informed decision ..

besides knowing the vehicle clutch / drive train torque and bhp linits

i'd want to know Exactly what any particular re-map tune would do ..
e.g. fuel pressure changes / injector timing changes .. and so on ..
and Exactly what the synergy .. ( or any other 'add on tuning box' ) does ..
i.e. how much extra fuel pressure / when .. etc etc ..

this page gives the info on the td4 fuel system specs ..
Freelander - Fuel Systems - Land Rover

~~~~~~~~~~~~~~~~~~~

i know .. after researching .. that If i were to opt for the 'tuning box' ..
the Synergy would be my choice ..

rekon stage one would be to check out that all engine systems ( in standard mode )
are in as good a shape as they can be ..
that goes for the clutch drive-train / suspension / tyres as well ..

in anycase ..
be worth having a good read of rover-ron's web pages ..

e.g.

ROVER 75 MGZT SERVICING

ROVER 75 MGZT ENGINE FAULT FINDING

Maf sensor problems.

and obviously .. the synergy pages ..

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. this is also linked to rover-ron's pages ..

http://energytuning.co.uk/remaps.htm

i think it's a 'sister-company' ..
i.e. obviously both tuning-boxes and remaps are within the combined knowledge base ..

.. btw: see the "SAFE TUNING POLICY." at:
http://tuning-diesels.com/about.htm
( mentions both 'remaps' and the 'synergy' box )

gone for the synergy2 with the dash switch,thanks for your more than usefull info..

Hi rifty,

A wise decision. The 'ron-box' is much more flexible and 'user-friendly' than a re-map, in my opinion.

Look forward to hearing what you think of it.

Cheers,

Singvogel.

What mod is this?........looks like there is something I may have missed!

Quoted from Tuning-diesels.com:

The turbo pressure is controlled in 3 ways: -

a) The most basic form rarely seen nowadays is where the ecu has no direct control - the maximum pressure is limited by a pressure driven actuator which opens the wastegate (exhaust bypass valve) to limit any further rise in pressure. Adding more fuel by tuning will increase the sub maximum pressure and speed up the build up of boost - i.e. the turbo comes in sooner, which is a good thing and very safe because the maximum pressure remains the same unless you also fit a stronger wastegate actuator spring or a bleed off valve (BCV) to mechanically raise the max pressure. see below

b) The earliest type of ecu control uses a vacuum operated wastegate actuator with an ecu controlled solenoid valve fitted to control the vacuum and therefore boost pressure. This works very effectively and is still used on the lower power versions of most smaller diesels but most 1.6L & above nowadays use a variable geometry or variable vane turbo.

c) This type has the advantage of providing more boost at lower rpm with the vanes in one position whilst still being able to maintain boost right up to maximum power rpm without over speeding by having the vanes move to the other position. A vacuum operated actuator or an electronically controlled servo motor moves the vane adjusting mechanism.

There is often much scaremongering by dooms & gloom merchants on forums which probably stems from petrol turbo horror stories. These armchair experts fail to appreciate that diesel engines are not at risk from the detonation that quickly wrecks a petrol engine if too much extra air makes the engine run lean. In fact, on a diesel with its unrestricted air intake, more air has a cooling effect and also helps to ensure more effective and cleaner combustion. This is why manufacturers are using ever high standard pressures - up from around 1bar / 14.5psi 10years ago to around 20psi these days. I've seen a peak of 22psi on my X-Type. Some engines also have an overboost feature where the ecu allows the boost pressure to increase above the normal maximum for upto 10seconds. This overboost feature should tell you that the standard boost is not the safe maximum but manufacturers, being ever conservative, only want you to have the extra torque for 10seconds! The Synergy 2b takes into account a overboost feature because it does not increase the pressure by a fixed amount regardless of the actual pressure - this is thanks to our proprietary digital mapping technology. eg, normal max pressure could be increased by 3psi, but overboost pressure by just 1psi or less.
