Tuning Box

I fitted a TUNIT box on my 2.0.litre 4 cyl diesel.
Better fuel consumption, and increased power.:thumbup:
On a D2 power goes from 115 bhp to 140 & 199 lbs/foot to 299 lbs/foot.:D
The company to contact is Tunit they are based in Chorley.
Take a look at the web site, the product and service is excellent, the unit can be fine tuned on a lap top, to a particular engine.
The other good thing is that you can remove it & reconnect it very easily.
If you change your car you can part exchange the unit for your new application if necessary.
The unit comes complete ready to fit and when you order it Tunit will set it up for your particular engine.

I have heard rave reviews about a company called DTUK, based in the north east of england. They do tuning box kits. Have never plucked up the courage myself to get one but have been considering it.

I had a DTUK box on my Astra 1.7 diesel. You could set different maps simply from the unit to suit your needs. I did 20k with this box and it was great. Where it really came into its own was when pushing on. My 1.7 performed like a 2 litre but at speed gave the consumption of a much smaller car. I did about 10k miles on European motorways fully loaded and was very impressed. :thumbup::thumbup:

This appears to be a piggy back type system rather than a remap, i.e. it takes the signals an lies to the engine making it do something else rather than actually changing the parameters of the map.

I have a remap on our lasses ST, it gained 60 bhp, loads of torque (transformed the car) and it really did increase the mpg, form 16 to 18 mpg

I would rather wait for/go for a proper remap like polestar do I just have to wait for them to pull their finger out and do one for the D4, than go for a piggy back

I have to say I am very wary of these type of systems.

These systems are not manufaturer supported such as are "proper" remaps?

I would certainly check with Volvo prior to installing one of these and ask the question "will this affect my warranty"? Also, make sure you notify your insurance company, big consequences may occur if you have an accident and the system fitted is discovered even if non fault.

If you trawl the Inet there is a lot of talk about tune boxes. Some praise them, some have not so good experiences including a reduced economy. The tune box manufacturers praise them of course. Proper supported remaps will obviously keep an engine working within acceptable tolerances. Do the tune box manufacturers guarantee this? Will they replace your engine if it does work outside of its tolerances and develops premature wear?

Big questions for me. Only my opinion of course and the choice is yours. But I would be very cautious. If you want remapping, getting it done properly with manufacturer support would be the route for me. Cheap alternatives MAY bring unintended consequence. :thumbup:

I am not attacking tune boxes by the way, just being cautious. Spending a bit more on a proper non gimmick remap may well be cheaper in the long run.

Kev,
I would agree with some of the points you made:
(1) You would be very stupid not to notify your insurance company, even if you had the Volvo supported Polestar conversion.
(2) "Yes" you need to check out the company in terms of its claims and the warranty offered. :dodgy:
(3) Do not under any circumstances be tempted by an offer of a cheap ECU flash tune, these people will appear on the internet and in local press.:huh:
Once its been done there's no going back short term gain long term regret.

Lets never forget that we have invested in a motor car for the vast majority of people has cost in excess of £20000.00, so lets take a responsible view.
You should ask the questions to the supplier, if in doubt kick it out as they say.
I was happy with the product I bought and fitted, it was supported by a manufacturer, I have now how ever decided to run standard with my D3 if I wanted extra power I would have looked at a T5:thumbup:

Unless your a boy racer, I can't see the logic in these.

Any extra MPG gain is going to be negated by the extra power & the urge to make use of it by putting your foot down. Possible insurance premium hikes are another down side.

Just stick to fluffy dice & go faster stripes :)

I like the idea of these kits but cant help but think if the engine is capable of more power with better economy surely the manufacturer would have set the engine up that way in the first place. There needs to be a trade off somewhere and I suspect as kev says it will be by way of wear etc which would decrease service intervals. Do the companies selling these kits suggest this might be the case.
You know what they say if it seems to good to be true it probably is!

By the way im not saying these kits are a bad idea, I just think some thought needs to go into purchasing them.

TDI Tuning Box Systems

Hi Imafudd,

TDI-Tuning is a specialist tuning company and offer both remaps and tuning box systems.

We achieve great results from the CRTD2® with the Volvo V40 1.6 D2 113 Bhp / 115 PS / 84 Kw with improvements in both power and torque whilst improving fuel efficiency. This PSA engine is a very common engine for us. The same engine is also used in Ford, Peugeot and Citroen brands.

Don’t just take our word for the results, if you refer to our Facebook page - https://www.facebook.com/tdituning you will see some very positive feedback from our customers with this exact engine.

Lots of points have been raised on this thread so I will try to cover as many as possible, so this maybe quite a long post!

In terms of how the systems function, they plug into your engine between the ECU and engine sensors. They receive and optimise the signals sent from the ECU and will increase and improve torque delivery. With the extra torque available, you can stay in a higher more efficient gear for longer, directly attributing to improving your economy.
Tuning box systems are able to safely release extra torque from an engine as manufacturers sell their vehicles with untapped torque locked in their ECU’s. This is for two main reasons –

1) They will use one engine for a range of different power variants but control power through the ECU so their ‘lowest spec’ model is actually a restricted version of the top spec version.

2) They have to ensure that their engines are able to operate adequately in a wide range of global environments and have to factor a large degree of tolerance into the engine to deal with this, often at the expense of users who purchase their vehicles in environments that have a high quality European fuel supply.

With regards to some general information on our tuning box systems, they are traceless and therefore are not traceable on your ECU. If the system is removed, the vehicle will immediately go back to its standard factory settings. Therefore, the tuning box leaves no history of its use. Our tuning box systems can also be installed and removed easily and can be fitted by you in a matter of minutes.

Our systems are also custom programmed based on our customer’s specific requirements and have multiple maps for easy adjustment. They can also be reprogrammed for any future vehicles at a small cost.

It’s common for customer’s to ask us about the impact it may have on their vehicle before purchasing a system. The tuning box will not cause any detriment to your vehicle. It will not affect your engine life span and will work within the manufactures tolerance on engine components.

With regards to your car insurance, we advise all of our customers to notify their insurer of the tuning system, as you would do if you made any modifications to your vehicle.

We offer a 14 day money back guarantee, so essentially you can trial the system to get a feel for the results. If you are able to visit our office in Chelmsford, Essex we offer a ‘try before you buy service’, we will also fit the system for you free of charge.

If you have any general tuning questions, you are very welcome to call us for a chat on 01245 392255.

Kind regards,

Steve

;) hehehehe, I wondered how long it take for you guys to pop up with your sales pitch. Fantastic. :D

Welcome to the forum Steve. Lol

I maintain my stance about being very cautious in respect of proceeding with such a product regardless of what all the brimming positive articles say on Facebook.

Very few recaps are approved by the manufacturer and the ones that are are not always the best, it is just that the 2 companies are in each others pockets.

I run a code red on our lasses st, it was seen as the best map at the time and the runs fine, no issues just extra go.

There are 1,000's of mapped st's out there and unless people have gone for silly power none have gone pop, in fact I am not aware of any even the 400bhp ones have gone pop because of te map, more an issue with cracked liners that effect standard cars as much as modded ones.

I would however agree go for a well known and respected company not some one who simply makes big claims

Boy racer.......well I suppose you could call me that or someone who simply wants to improve on what the manufacture did (they have to play it extra safe) if there was not further tune-ability to the engine we would not have different performances out of the same units like d3 to d4 and even the highest standard out put has more potential hence why polestar and the like add further improvements.

I have to say I can't really see the point in mapping a lower spec car when you could simply have bought the next one up but I can certainly see why on a top spec like on the t5 or he d4

Re the mpg, I drive our lasses mapped st the same as I did when it was stock, I.e. enthusiastically, but now it is quicker but I still return an extra 12.5% better fuel economy with the map than I did without

As a retired accountant I don't think I qualify as a "boy racer", but I do find this topic interesting.

I have no experience of using any of the brands mentioned in this thread, but a few years ago I owned a Defender 90 which I had chipped, providing a noticeable improvement in performance without affecting fuel economy, and 12000 miles later was still going strong when I sold it.
I have had a number of my bikes professionally modified, tuned, remapped, etc., and have all shown useful increases in power, torque, & mpg. and none suffered mechanically as a result.

On a number of occasions I have wished for a bit more "go" from my D2 engine, and have sometimes wondered if I should have bought a D3 instead. The availability of a relatively inexpensive tuning box appears to be an answer to my prayers, but I do have some concerns as to whether the Citroen/Peugeot/Ford 1560 lump fitted in the D2 is a suitable candidate for upgrading, for the following reasons:

1. This engine does have a bit of history concerning premature turbo failure, and it is possible any performance upgrade may exacerbate this tendency.

2. I note that Polestar and DTUK do not offer any engine enhancements for the D2 - is this a tacit way of saying "bad idea"?

You're not the first to mention this 'Turbo' issue. Under the standard warranty, if the turbo fails within the first three years, is it covered?

I was hoping to keep this car 5 years (another 4 to go) but could it be wise to shift it before the warranty expires?

Does anyone know how much a new Turbo is?

D2 turbos

The turbo problems on this engine are quite common, the engines carbon up inside this blocks the oil galleries and starve the turbo of oil .
If a turbo fails its no good just changing it as the new one will be starved of oil and that will fail in a very shot time, you can strip down the engine and try and clean all the carbon out but its a lot of work and expense and not always successful, Ford recommend fitting a new engine and turbo.
If I owned a D2 engine I would change the oil every 8-10000 miles I would use the highest spec fully synthetic oil and would use engine oil flush at every oil change.
Short trips make this problem worse longer trips allow the engine to get hotter an burn some of the carbon away.

Spot on, I would also use vpower diesel (I already do in my d4) as it burns cleaner.

If you search for Ford, Peugeot 1.6 Turbo issues you get many and various on the net. I have to say that it would appear to be relating to older engines but I seem to recall that the D2 is anew variant and therefore, one would hope, better than the older ones.

I guess you are happy that, with this prospect on the horizon, that you leased your car Kev. I'm now planning for a change in two years time instead of the four I had hoped for!:huh:

On another issue, was forced to drive 13 of the 17 miles home last night in nose-to-tail traffic with numerous stops and hold-ups. The stop-start obviously sensed that it couldn't maintain battery power and - stopped. By the time I got home the mpg was 40.2.

Can't blame the car and can't blame the other drivers either. We're all in the same boat, literally if it rains much more!
