Lower Output Issue for G310

Hello,

I have a friend in China is looking for a way to get the stock power output back。 The engine output is only 21kW in Chinese market due to emission control or whatever other issue. He wants to get that 4kW juice back.

Do you guys have any thought about it? If it is a ECU issue, he probably can get that missing 4kW back with a ECU replacement. But he is worrying about BMW might do something else on the baby G310.

Hi whatever,

According to realoem.com, there are 4 major differences between the eu version and the cn version.

1. Entire throttle body and injector
2. Entire main wiring harness
3. Drive sprocket teeth 16T -> 17T
4. ECU has special label

Judging from these, lower power output will not be an issue of ECU alone.

You could try the Akrapovic exhaust S-B3R1-RC/1 which has no Catalytic converter. It is a full system and is easy to put on. This is the carbon fiber version as the stainless version has a ball upstream for a catalyst.


As there is no Power Commander 5 for the bike, try www.magnumtuning.com for extra boost (fuel/air, etc). This should get the 4Kw back plus maybe a little more.


Let us know if it works out for him.

I wonder if BMW dropped the compression for the Chinese market?
No sure how good the fuel is there outside the cities so maybe that is the reason?
