Tuning 320d

[rapagon]

Does anyone of you have any experience with tuning the 2-litre dieselengine in 3-series? I currently have the standard 2001-edition with 136 BHP / 280Nm, and seriously - that has to change! I have found several add-on-boxes to boost up the power ( P-box, Python tuning etc..), but i have no experience whatsoever tuning dieselengines.. How much power is it reasonable to aim for? The one's I've been looking at gives 163 BHP and 343Nm. Will the engine/transmission handle that?

If anyone have any experience with this type of dieseltunig, I'd be happy to hear from you!

i know theres alot of products you can get for american diesels that boost you up an extra 50 hp, but i have no idea about diesel bimmers. try propane injection............ (jk, but it does work)

Normally the maximum power increase you can do by chiptuning the engine is around 20% extra. This way you won't hurt the transmission and/or engine. I looked up the specs for your engine and I've seen values around 160-166 hp and 300-360 nm. So you'll be fine when you chip your engine towards 163 hp/343 nm. The reason BMW doesn't deliver the car with that amount of power STANDARD is that you need to have a good quality fuel and oil. Since the car is manufactured for the whole world (including countries with bad quality fuel) they 'downtune' the car a little bit. But since you live in Norway you will not have problems (btw have you tried shell V-power diesel? works great). But be sure you go to a well-known company with a good name. They will probably also give you a warranty for your car. Prices in the Netherlands for a 320d are between 580 and 770 euros.

Good luck
