Diesel tuning boxes - are they all that?
Discussion
So these diesel tuning boxes that are for sale all over the place.
Do they actually deliver what they say on the tin? How do they work? Are they really properly developed as the manufacturers claim?
Im talking about boxes in the £100 to £300 price range, not the ebay resistor in a box type.
Theres various ones around for the landrover td4 engine and they promise fairly good results, but do they actually work?

Yes they can work. Although, of course, it depends which box and which car you plan to use it on. e.g. the STS box from Shark Performance http://www.sharkperformance.co.uk/sts.asp for use on the 1.9TDi gets very favourable reviews.
Edit: I think the STS will work on other engines, as well as the 1.9TDi, I don't know which though, so best to contact Shark.

It works by fooling your ECU into thinking what the engine is doing so that it changes whats happening and the performance is increased.
Personally I wouldn't plug one into my car, if you want to tune the car do it properly with a proper remap not with one of these.
As far as I am aware the STS box from Shark is a proper remap. My understanding is you fit the box, download your stock engine settings (so that you can always return to these settings), you then email Shark your stock map and they take into account this, your exact engine and any mods, they then email you back your remap which you upload. I would imagine with Shark's experience they would err on the side of caution and send you back a safe remap, and if you want anything more exotic it would be entirely at your own risk.Personally I wouldn't plug one into my car, if you want to tune the car do it properly with a proper remap not with one of these.

Can you show me where you can get an easy 20% power boost on a petrol car for £100?
void a warranty and crudely alter the fuelling on a derv leading to egr faults and rough running for £100 or get a proper remap for £300 on a turbo petrol? I know what I'd do.derv is for tightwads and hgv's.

I've ran various tuning boxes on various cars and found them to be very effective. Certainly no rough running ever, no egr valve problems - only positives in fact. But i guess i know that because i've used them rather than listened to hearsay on the internet.
They can easily be removed if required, therefore very likely to impact a warranty - unlike a remap which will - if the fit hits the shan.
I thought people with such primitive opinions of diesels as you didnt really exist anymore, but i guess theres still a few of you living in the past.
20% power boost from a non turbo derv for £100? have you got an example thats independantly verified?
to compare a turbo derv to a non turbo petrol is pointless.
i drive new diesels all the time at work and hate them, getting into my petrol car is such a luxury after a few hours in an oil burner.

The acquired wisdom of forums, blithely repeated.It isn't as simple as this, and the above advice is insufficient for people to make an informed choice. Plug-in tuning devices come in varying levels of quality as do remaps. Some of the best tuning companies offer plug-in boxes (Steinmetz for example). Some 'reputable' remappers simply chuck a generic set of numbers into your ECU using a cheap Chinese Galetto clone interface and a 'netbook yet charge a premium 'coz remaps is better than boxes, innit'.
heads spouting off, totally off topic. I despair of this place lately.Gassing Station | General Gassing | Top of Page | What's New | My Stuff
