535d chip - on ebay - anyone tried them?
Discussion
Just stumbled on this on ebay
http://cgi.ebay.co.uk/Diesel-Economy-Tuning-Chip-B...
Must say it got me interested - 5 year guarantee and money back for 30 days?? Has anyone tried this and if so, any feedback.
I know there are alot of people who say "535d + chip = bang" etc, but perhaps someone who has actually done it could give us all some thoughts?
Cheers!

Not being funny matey, but you must be off your head if you are seriously thinking of plugging in a generic £99 "tuning chip" off ebay into any motor, never mind something as expensive as a 535d. Save yourself an engine explosion and save up a bit more and go to someone reputable like DMS if you really want to remap your 535d.
The clues are in the advert when you plug it across the commonrail pressure sensor.
All it does is lie to the ECU that fuel pressure is lower than actually measured, so it increases the pressure, and more diesel shoots in than the car planned.
The problem with this is it put more strain on the high pressure injection pump (which costs a fortune) and also put extra strain against the closed injectors trying to hold back the pressure (6 of these that also cost a fortune)
With a remap, you will get the extra fuel, but by controlling injector duration (sometimes a modest increase in pressure, but not close to a tuning box) and also increased boost levels, so more air too, which means less smoke.
You are also able to fine tune the torque protection maps so it won't twist itself into a ball (whilst the original ones still exist in the ecu, it knows torque from the power it will get from a certain amount of diesel, and i knows how much diesel it needs to create a black apocalyptic smoke cloud, but those figures are useless when it squirts in more fuel than is needed)
On the plus side, when you need to take it back for new injectors on warranty, you can remove it

I imagine they use Piezo Injectors right? which cost about £800 for a setAll it does is lie to the ECU that fuel pressure is lower than actually measured, so it increases the pressure, and more diesel shoots in than the car planned.

DMS or another warranted and well known chip installer.
It may not cause any damage - but what if it does?
And on the flip side, why the feck are these re-maps so bloody expensive? They're just a few kb of data - the prices make SMS data rates seem cheap!It may not cause any damage - but what if it does?
I can understand some of the R&D costs, but at the end of the day the re-mapping business is a license to print money.

In the same fashion any software seems to be a money spinner once development has been concluded and you're simply selling a branded burnt DVD. Don't forget in this instance DMS for example offer a warranty and that has to factored in, as does ongoing development and running costs of the company.Whilst it they seem expensive, nobody has to buy these upgrades.
