only if there was a place in the states that can do this. I really dont like sending my ecu out, id wanna take it to a shop and have it done there.

Can i upgrade my 3.0i

Bmw do do it!Within their own model range,you have the same engine with different power outputs.For example ,the M57 engine (3.0 Diesel MK1) has 184,193 and 201,on 3,5 and 7 series!Here its obviously a marketing policy as well as the fact that the heavier the car ,the more power it needs!So,Bmw are really telling us that there is some tolerance in increasing the power in this engine.
Another example is shown in your "v8 diesel engine code" thread.The 745 D will have its engine uprated from 300 to 330bhp.

The drawbacks,in case of the more hefty 20% increase in reprogramming the ECU ,we can mathematically apply the same to engine/injection/turbo strain and wear!
The most crucial is the increase of temperatures inside the combustion chamber due to more heat generated by more fuel and boost pressures.(this could be offset by a larger intercooler,as in ,my case!)

More boost pressure ,means the turbo will be spinning faster ,so instead of servicing the turbo at 100,000 miles,one will do it at 80,000 miles!
Higher injector pressures will also decrease the life of the injectors ,so theoretically you are more likely to have to replace one sooner, but never seen one fail so far.
So,yes I do believe in sensible power increases!
I dont believe that the dealer will not find out if your car has been tampered with!Normally when a car goes in for a service,the dealer doesnt need to look at the "modified file" as he is not looking for it!However,should the car need a software upgrade and the ECU is reset,GOODBYE power !

Good info :thumbup: . You're right, with the diesels, larger ic would help a lot when chipped. I'd think that a turbo timer and a heavier weight oil would help with maintaining the turbos as well.

How far are you from Redmond? There's a place there that can superchip your car. check www.eurobahn.us for more info.

THANK YOU! i can easily drive to redmond its like a 15min drive! so much for me researching stuff thank you very much for finding this out.

how do these "chips" work in
conjunction w/ CAI's and other
such mods?

No problem :) Call them to make sure; I'm assuming they have it since I got the info off Eurobahn's website and it appears that they are the US distributor for Superchips.

According to the gentleman I spoke with at Eurobahn, he said that the reprogramming works with CAIs, exhaust systems, etc. without any problems and that it doesn't matter if the reprogramming is done before or after the other mods. I think I read somewhere that you still retain the adaptive programming that comes with the original "chip", so that if you add on a performance mod, it will adapt to the changes those mods create. I did this research late at night on medication, so best bet is to call Eurobahn to find out more info. They seem pretty helpful.

My 'petrol guzzler' certainly has that low down torque you refer to. The performance improvement is certainly very good on the 3.0d and makes it much more tolerable to drive. My brother's 3.0d is chipped by DMS and whereas before it was a little slow joining motorways and not much fun overtaking other cars, now it's fine.

Torque now feels similar to my 4.8is for the first few thousand revs but thereafter the 4.8is just dissappears. Remember the 4.8is will reach around 160mph (indicated) and continues to pull with such torque all the way up to 6500rpm.

but it's still a petrol. Diesels rule!! lol.:boogie:
