Chatting to a motor homer last night, he has one fitted says it increases power and a fuel economy on a diesel, has anyone got one or looked into it?
 
well you got something fitted to your van you dont know what is it and did martin push that switch that was found at st day

+40% Power
+35% Torque
-20% Fuel

Looks a bit to good to be true.:idea:

And all achieved by electronically increasing fuel pressure? So why don't the engine makers do it in the first place then?

Engine settings are arrived at conservatively on the assumption that vehicles may not be serviced properly or that less than perfect fuel may be used. If you have a vehicle that is properly maintained and you're not buying your diesel in Outer Mongolia chipping can improve an engine's performance. Drivers can use that increase in efficiency to give more speed or to drive as normal and get better mpg. There is plenty of evidence that this works.

However, having it done properly isn't cheap and people need to calculate any fuel savings vis a vis the initial expense. They should also inform their insurer, but when we had it done on my business partner's Mercedes S320 diesel car, there was no increase in premium. He is a adamant that it gave a significant power increase, which is what he was after. He had the car in its chipped form for five years without any problem or MOT issues. He's now got the latest model which he says is a huge improvement and isn't bothering having it chipped.
 
If anyone claims to give you a fair bit more fuel economy then they are telling porkies.

However, you can get better economy with a chipped engine but nothing like the claims made by sellers or most manufacturers.

I have a Tunit box fitted to my van and I get marginally better fuel economy. The reason being that it has more Horse Power and I can get up through the gears quicker. I can also maintain a higher gear for longer and both of these things give me a little better economy.

If I used the extra power to drive faster then I would be worse off. The drag of a very un-aerodynamic vehicle rises as the square of the forward speed of the vehicle. Faster speed means higher revs and this also is less economical for a diesel engine.

Hi All,

What if it blows your engine? Any back up? No such thing as a free lunch,Ask Fiat or what ever rig you run if it's OK.

But you need higher revs to get the benefit of the turbo don't you? My pals used to increase the waste gate spring tension to increase power (err & fuel consumption, & temperature of turbo!)

There are many free lunches I can assure you. What you're saying is that there is never room for improvement! Engine re-mapping or chipping does work and, as I said earlier, my partner ran a quality car that was remapped for five years without any problem. I'm not sure how re-mapping can cause an engine to blow up either, all that it does is tune the engine and reset the parameters which have been chosen to reflect the worst possible maintenance and fuel scenarios.

Here's a test from Auto Express. Chipping can work and there is plenty of evidence to prove it.

Back to the box, I suppose it rather depends, like many things, whether the return would cover the investment!

Yes, for many people that will be the important factor but for others, especially motorhomers and caravanners, it's the increased bhp and torque that could make driving much more pleasurable that may be the big advantage. For instance cruise control will work on steeper slopes without dropping out, saving you changing down, and driving in mountainous countries could be much better.

If increased mpg is what you want and you average the cost of remapping at say £100 a year over five years, and if you improve mpg from say 30 to 35 and you do only 6000 miles a year, you'll still be quids in. If you do 11,000 like me you'll save 52 gallons a year or about £250 every year.
 
I have had a few of these boxes on previous vehicles.
They do increase BHP by adding more fuel, but if you use the power you use more fuel!
 
well you have a black box fitted to yours and the switch is under the gear stick well not sure what is was grumpy two had look also
 
I might get two fitted. You can never have too much power.. :lol-053:
