Tuning Boxes.. are they any good?
Discussion
I just saw these on eBay:
http://www.chipexpress.com/diesel-tuning-box-toyot...
They're £395, claim to increase the power to a max of 169 from 126bhp and torque to 385 from 300Nm.. The main thing that would make me consider one of these over a remap is that it can be removed very easily?
But don't remaps cost the same, if not less?

my pal has one on his Diesel C3...1.4 hdi.... he reckons its made a huge difference, the one he plugged in, yes plugged in opened up the parameters in the ECU to give better performance.... job done.... now his credentials are that he is a motorbike racer and he knows his way around engines...nuff said

Any more info on the benefits he has experienced ?Said 1.4 hdi powers my car. I say powers, but it doesnt really have any, just a nice shot of torque 1900-3000rpm
Maybe you should buy one of those electric fan turbos or cork screw tailpipes as well. While you're at it pour some tea into yourself.
Looks to me like a piggy back ecu if that's the case flush your warantee down the toilet.
Could be the real deal but look at the market for this sort of thing and there are a million and one scam artists trying the same deal.

yep, they just plug in between the rail pressure sensor, and the ecu, and tell the ecu the rail pressure is a bit lower than the sensor value.
The ecu increases turns the high pressure pump up a little to hit it's original target, and the intercepted signal now matches what the ecu wanted to see.
the problems are you have increase the load on the high pressure pump, and the injectors, which can start to leak (they will be holding back thousands of bar pressure. a car tyre might be 2 bar, the pressure at the bottom of the Mariana Trench is about 1000 bar, and your fuel rail can be 1300-3000 for some real heavy duty stuff)
With a remap, you'll get increased air from the boost pressure maps, increase fueling from the injection quantity maps (which can be as simple as just keeping the injectors open slightly longer) and recalibrated smoke and torque limiting maps which avoids the M-way black clouds, and the gearbox trying to explode.
