My dad is one of these caravaner types who likes to go to eruope on caravan holidays. (caravans...yes I kinow!)
He is a member of the caravan club and in their magazine he was asking me about the below company's advert for a plug-in power increase for his 2.5L Discovery turbo-diseasal.

My reaction is that it is just another 'magic' ecu trick box that doesn't really do anything.
But am I right?

Does anybody have any experience of such a 'plug-in' device, or is it just all 'word of mouth' reports?


Cheers.

Iv heard about these kind of diesel tuning boxes on another forum, people seamed impressed with them (they were for the 1.7cdti and 1.9cdti GM engines)

Alot of turbo-diseasal engines can be remapped just like turbo-petrol engines can, to get pretty decent power increases.

Just interrogate Google smile

Yes, I was aware of this, but mapping an engine for one purpose compromises on another.
Map for more power and it usually means the engine requires more fuel and air in the cylinders....which means lower fuel economy.

The above 'magic' box states that it does both.
I am just wondering if there was a map available that increases power/torque and also economy then why didn't the manufacturer put this map onto the ECU from the factory?

Ive got a tuning box on my focus and the most noticable thing is the torque curve, better mpg and thats been on for over 30k miles now. No problems no extra smoke and easier to tow stuff, so as for your dads needs its a cheaper way for easier towing.

By uprating the power- and more importantly the torque- driven normally the engine shouldnt have to work as hard to get upto speed and less gearchanges would be needed.

The manufacturer would map the car safely so it can offer a warranty and a reliable product.

An engine producing more power would probably wear quicker, particularly if driven hard.

OK...well I might be being too negative with regards to this tuning box.


Would you say its money well spent?
If, so I think I'll tell my dad next time I see him that it might be a good buy.

the magic box just pumps in more diesel.
the reason why manufacturers don't go for full power maps is because a) they are often aiming for a certain power output, if you change the manufacturers bhp into kW, you'll probably see it lands on a nice round number.
b) they often aim for a certain emissions level, but once the car is out on the road in private hands, you don't need to stick to it as rigorously as the manufacturers do

It's a bit of a compromise between reliability, power and economy. With these devices you may get more power or economy but not both at the same time. Which 2.5l disco are you talking about as some can't be mapped and they all generally need a bigger intercooler to see any benefit.

I got mine as i had a terrible lag low down in second gear, so when towing and turning into a side road etc, it was hard work to build up, with the box its pick up is better and smoother, its not as hype up as people say but for the right reasons makes alot of difference for better driving, I only paid £99 for mine off fleabay, so shop around, they all do the same thing.
