I noticed someone selling a second hand tuning box on ebay. They gave it rave reviews.

Found this website, which I think is the same as the ebay item:

http://www.dieseltuner.co.uk/

What does the rest of the forum think?

i have seen thing like this before and don't think they are worth the money and seriously looked into it on my previous car I looked at a company called "tuneit"

IMO the FL2 doesn't need any extra power for everyday motoring in the UK

The new ones come with a 12 month engine warranty, but the eBay item wouldn't i presume due to it been second hand

I wouldn't expect a eBayer to sell something on there and say it was Sh te, look for independent reviews, (not on the manufacturers website)

It is also a quick way to throw away any warranty that LR are giving the engine aswell

I would then speak to the guys over on RRS/disco3 who sponsor the site 10forcash (runs Torque tune) and Turbochip solutions if you want to get more power Former Mod/Member, with the most post & Chicken George Arch nemesis

I have heard similar problems with Tuneit.

However, I have also heard that this outfit, Diesel Tuner Systems, are very good.

The key advantage of this system to a remap is that you as the owner are in charge of the installation. It can be fitted and removed as required without the need to refer back to the company that carried out the software update. In addition, it will not be wiped out by any future Land Rover software upgrades.

There are big differences.

A tuning box quite simply intercepts the signal from the ECU and in effect tells the fuel pump that the pump pressure has not been acheived and it increases it, hence more power.

The down sides to this are that all the safety parameters within the management system are bypassed. But they can be unplugged and there is no evidence that they were ever installed. As well as the FL2, I also own an Astra 1.9 CDTi and the tuning box's on these engines have always been very reliable. DTUK is the best place to go for tuning box's.

In my honest opinion, re-mps are much better and safer. A re-map takes the original engine map and alters fuel pressure, boost pressure and injector timing while still keeping things within the factory safety levels. A system like Superchips Bluefin, allows you to re-install the standard map at any time. Also, should there be any factory software upgrades, the Bluefin can read the new software and Superchips will alter your re-map to suit.

Like everything though, if you abuse a car with a re-map, or a box you will get problems, but if you treat it with respect, you should never have a problem. Freelander 2 HSE Lux 2013MY - Barolo Black with Ivory Leather. Alpine DVD - Privacy -Evoque 20" Dynamic Wheels and more to come.........

Most, but not all in-line tuning boxes are an elaborate box with a 2p resistor inside that fools the ECU into over-fueling to increase power, which the Lambda sensor then corrects for. They increase power and generally fuel consumption also.

Good remaps are usually better as they can properly control the engine if correctly done.

They can increase power safely & economy as most manufacturers maps have to account for all markets worldwide and a vast variation in fuel quality.

Here in the UK our diesel is good, and a good remap can easily be done to increase power and economy.

Turbochip do a good one for D3's which even some Land rover dealers we're offering when I had my Disco, they would even replace it if it got wiped, & for free, see the sister D3 forum. However they don't seem to offer anything for the Ford PSA 2.2 in the FL2 sadly or else I would have been on the blower to them by now.

As with any performance upgrade, this generally necessitates more maintenance, and oil changes are recommended to be done more often if a power upgrade is used as turbo diesels tend to destroy their oil rapidly at the best of times.

Considering the 'minimum' quality of the oil the main dealers use (see 2 stroke thread & others) I would still change the oil more frequently if I were to use a power upgrade as I have on previous cars. If not I would use a better spec oil on the factory schedule as much for peace of mind as anything else.

I do like crawling about under my cars though and it takes less than an hour

Tuning boxes on common rail diesel engines can't function if they are "2p resistors". Most now are digital & use a microprocessor, as even the older analogue ones don't react fast enough & cause fault codes/limp home.
Diesels don't have a lambda sensor. As for fuel consumption, well usually you find that the econimy is better as you tend to have more torque for normal driving. If you drive it flat out all the time, then the increased power uses more fuel, but on average, they usually save fuel.

I realise this and was generalising wildly. As spotting the good sytems from the poor ones is a minefield for the average punter

I had the Piggy Back Ralliart system on my last Shogun which did as you describe increase fuel efficiency by increasing torque for general driving and the car felt all the better for it. The difference being it was supplied fitted, and warranted by the UK Mitsubishi Importers.

The good thing about Superchips Bluefin, is that if the dealer re-flashes the ECU with the latest Land Rover Software, you simply re-read the ECU with Bluefin and Superchips will then re-do your re-map based on the new software free of charge.

The fact that Superchips bought and still own an FL2 TD4 for the development speaks loads to me. Freelander 2 HSE Lux 2013MY - Barolo Black with Ivory Leather. Alpine DVD - Privacy -Evoque 20" Dynamic Wheels and more to come.........
