BMW 116d chip tuning or remap

[frosty984]

Hello,
I was thinking about chip tuning my BMW it is a 2.0 turbo diesel with 115 hp. Any info about this engine? And one more question why BMW (and others) make a 2.0 engine with 115, 140 and 170 hp or Mercedes a 2.2 with 136, 170 and 205? (these number are NOT accurate) And that 2.2 turbodiesel from mercedes with 205 hp has 500 Nm and that must be breathtaking for a 2.2 diesel

Hi, be better to remap. A chip just fools the ecu in to producing motley power. A remap is much better imo.

They make different power outputs for various reasons.....insurance is one,
also the lower powered cars tend to be more forgiving if a service is missed and the lower powered ones are sold in countries with poor fuel quality...

if all things are equal (mechanically) and your car is only electrically restricted then a remap should produce the same gains as on the higher powered models.....

I think there are some mechanical differences as well between the engines

id say the turbo is different and thats about it really....

I'm inclined to agree. Possibly uprated cooling on the higher tuned derivatives and maybe injectors with higher flow rates but that is probably about it.

115 bhp from a 2.0l isnt a great deal now....id probably say it uses a wastegates turbo....

It's quite low - considering the 323d manages 204bhp from same two litre unit
Maps to nearly 270 ! ! !

Well...its does have 2 turbos....so yes id expect it to produce more topend

Yeah - that probably helps a teensy bit

So, does chip tuning actually makes any perfomance change and does it harms the engine?

Chip tuning is old old old school. In the very dark days they dismatled the ECu and soldered in a different EPROM.

You can buy plug in tuning boxes even now. Avoid is my suggestion. Your car is Euro V compliant and they WILL wreck the particle filter over a few thousand miles.

OBD remap is the way to go.

Good luck and enjoy

Found a remap to 166 hp/4130, and 362 nm/1700 good enough?

Sounds reasonable

 

[jarrus]

sounds alright to me
