If you could get better mpg , and more power from adding this box, would the manufacturers not use this setup and sell more cars?

But then again i am a very cynical person!

I did think it was a variation of the "Italion tune up"

a bloody good thrash, just like my 7 got five mins ago, and its still not running right

One of my clients has one fitted to a Jag diesel let me have a go with it fitted then took it out without it. There was a definate difference in power and economy according to the cars computer.
Cheers,
Bob

i know what you mean about manufactures not using them,better power and more mpg but how can the same engines in some cases produce different bhp and people who remap ecu is this not the same????

As we all know production engines are set up with many compromises in order to meet imissions targets etc. They are not set up to their best.

Surley the boxes are removing some of the many compromises, improving things here and there.

It is true to say however that the VW 140hp and 170hp diesel engines are the same, it is only the electronics that make the difference.

Sneaky VW dealers buy the 140hp cheaper from VW and then adust/Chip the ECU to release the power and sell them as the more expensive 170 engine car to us.

new car have to meet the reg's of the country thay are sold in (noise, emissions, taxation class) so thay design one car/engine to fit them all also looking at refinement, relieability and smoothness of an end product


common rail diesel engines are quiet simple to get more bhp and mpg from buy changing the injection timing and length.
thease boxes are piggybacked in and are effecting signels in and out of the ecu to change injection timing and length.

i have looked into getting a "box" for my car but there seems to be a influx of cheap simmular looking ones from unknown sorces coupled with allsorts of common rail systems and partical filters been added its a bit of a minefield

the makes that do have any kind of good rep are much more expensive but are probably worth it

Looked at getting one for our CRDi but after a bit of surfing discovered that with a DPF they can cause long term (and shorter term) issues. Seems that in certain parts of the EU they have been using DPF's longer than us and a lot of people have had to ditch their tuning boxes after very expensive repairs, £1000 to replace. Did not fancy £1000 bill after spending several hundred on the box thus put the idea in the bin. There was also much discussion that the extra mpg is just clever fooling of the ECU by the box, when people did a real mpg test there was no improvement and several on one site commented that if you used the performance you got loads of smoke and low mpg.
