Yes you can!

There is a team on the Gumball rally who run a highly tuned 330d (or d3) which I believe sports around 300bhp (never mind the torque!) and comfortably outruns a Ferrari 355 - check out their videos:-

www.antandpete.co.uk

I am planning to up my 320d to around 200bhp. There are a few other forum users who are intending to do the same...

Diesel Power!

Bigman,

Who do you plan to go to for your performance upgrade.

I've got a 320D M Sport on order and notice that Superchips can increase the power by 33bhp to 196bhp.

Do you know anyone who can better this ?

Tempting though it is, be aware that these 'upgrades' will invalidate your warranty!

UK,

They didn't invalidate the warranty on the Audi TT that my mate currently has. His cylinder head gasket blew after two and a half years and 55,000 miles.

Audi did the full diagnostic check and did not pick up that the ECU had been re-programmed. The work was done free of charge under warranty. If Audi cannot spot the engine has been chipped why will BMW be any better ?

I guess the big question is if BMW do an update of the software, will that overwrite the chipped program and put it back to stock performance levels ?

Your friend was lucky! I've heard of cases where warranties have been invalidated. Seems a big risk to me. Besides, the performance of BMW diesels is superb and (in my opinion) better than much bigger petrol engines - so who needs the chip??

I thought the new chip just sat in parallel with the old one disconnected??
I.e - you have a problem, you take the new chip out and go back to the old. Anyone confirm this?

SOme info I received from a recent enquiry re chips.

Thanks for the enquiry,

I have had about 5 e-mails in 2 days about the same car!

Yes we have the units in stock, I'll put them on the website today I think, it's the same unit and lead as the 120d 163bhp.

The gains are as follows -

BMW 320d 163 PS E90 163bhp 188bhp 340nm 390nm CRD-System CDI2

It’s a plug in system, and very easy to fit on that engine, removed in the same way for service and repairs.

The unit comes with our 30 day refund offer and 3 year warranty.

Any tech support required via e-mail or phone to get you up and running successfully.

I’ll list the unit this morning on the BMW data page, or you can order the 120d 163 unit - and advise us it’s for the 3 series when you get to the ‘additional info’ box on the customer details page.

Or you can ring and order 0845 686 5000.


P.S - No1 tuning magazine Max Power rates our products too -

MAX Power Review 12/2004

I would be very interested in buying a chip that gave better performance for the 320d - if anyone buys the Dragon chip could they post feedback on improvements and how easy it is to fit and remove.. thanks

A guy that I work with has a 120d with the 163 bhp engine that is in the 320D.

He had his chipped at Superchips on Tuesday. They re-programmed the existing chip via the diagnostic serial port and upped the power to 196bhp. Cost was £500 and they claim that he will see a gain of 2 to 3 mpg as well as better performance

The power delivery is really smooth and the torque is amazing.

Their website is www.superchips.co.uk

There seem to be 2 real options: re-programming from Superchips (£400-500) or the dragon box (£300).

Will BMW know you have re-programmed when you take it for a service?

Anyone test driven the new 330d? It packs some 240bhp now.
