A couple of pics for Dan a plugin I bought a couple of year since. At a rough guess there must be atleast £20 of bits in there.

you'd be right about that, i take it you had bad experience with this unit Johnson?
i will get pics of my units up when i get back from england, i have a VP30 unit out at the shop.

I didnt have a bad experience as such with it as it happens, it worked quite well but not as well as the seller claimed.

well i put a box on a 530d last week guy is more than impressed with it, he went out and raced a 535d and wiped the floor with it. i will get some of our cars on a rolling road soon, our figures are real figures, all our boxes are developed on the rolling road in Germany

Looks like an over engineered variable resistor.
I could take most of the parts of that and it would still funciton the same.
i.e Poorly and in a "not fit for your car or safe" way.
Not one of mine BTW

Put a pic of yours up and lets have a look see what thats like.
"not fit for your car or safe" can you tell me why?

exactly what i was thinking, it looks like the "componants" have been fitted to the PCB by a 5 yr old,
i think i have seen these before? Ebay special?

Lets see pics of the inside of yours then, the pair of you are quick to critisize but very slow at putting pics up.

as i said mine is in the shop, dont have time to get it as i am at work here and im heading away this evening to england, i will put pics up tomorrow evening

This is how mine works does your s do anything different

How it Works:
Todays diesel engines have many sensors which are controlled by the vehicles ECU these signals are processed many thousands of times in one second to maintain that the vehicle is running at its optimum efficiency and keeping the emissions and economy at acceptable levels.
The idea behind the tuning box is to intercept the signal between the ECU and the injection system usally the common rail and basically allows it to inject more fuel into the cylinders thus producing more torque and power, and because of this the engine is running more efficiently the fuel consumption is also improved because you would have to use less throttle for similar conditions.
So why don't the manufacturers do this....?
You may have wondered why a manufacturer can have the same engine in different models but they can have different power outputs.
This is not due to the engine mechanics as they are usually built to the same standard, but its down to the software installed into the ECU which governs the engines output.
Manufacturers do this because of the strict emissions regulations and tax bands especially for the company owned driver. Many countries around the world relate their tax levels to the KW output of a vehicle or the emission levels.
Installation:
All these systems have been designed to be compact and easy to fit they are supplied complete with the correct OEM wiring loom and connectors for the vehicle application and can be installed with the minimal of mechanical ability thus making it an ideal diy project, most units can be fitted in around 10 minutes and they come complete with full support.
