Re: ECU remapping...
Hahaha... no worries. Here goes...
To make 6 more horses out of a NA engine is not that difficult. It is probably done by tuning the ECU.
On the 323 and 325, certain hardwares are still different, in order to boost that much of a horsepower.
On the 320s, that we have done, what you ask for is not impossible.

specs on paper
a. E90 320 (pre-facelift) = 150bhp & 200Nm torque
b. E90 320 (LCI) = 156bhp & 200Nm torque
323 was also improved from 170bhp to 190bhp right
But, 323 use 325 engine but detuned. I guess they just have to open the tap bigger to release more power
For E90 320, both pre-facelift and LCI are using N46B20 engine right.
So, how did BMW gain the extra 6bhp without making any changes to the engine ?
Does that mean E90 LCI just use a different ECU map on the same engine to produce more bhp ?
So, we can improve the ECU map further to produce 163 bhp & 210Nm torque (5% gain) ?
I'm getting more excited for 8% gain
I know snowdog has PMed manys liao for the % gain
