    Modification ECU Remap For 318i

    Hi all,

    Currently just get hold of a preowned E90 318. Understand that the engine is basically same as the 320 so was wondering whether is it possible to retune or reflash the ECU to get back the "loss" power. Not hoping much but would be good if can get back to the stock power of 320.

    Advise greatly appreciated

    believe the 318 to be on N46B18 while the 320s are on N46B20... the latest being N46N20 with 168bhp and 210Nm...

    Hi thrust,

    the power may not match the 320i but it definitely boost some power then your stock now (after re-flash) .........use light-weight rims.........

    improve the handling like upgrade to coilover and sway-bar (ARB)

    happy mooding
    cheers

    Are you sure there is N46N20?

    Based on the pwr & torque, it should be N43B20 O0. It is not sold outside of EU.

    It is not as simple as retune or reflash. It might involves some hardware change, like DISA. Honestly, Enjoy ur ride. If pocket itchy, change to 17" Volk Racing wheels that might help with butt feel.

    Sorry OT a little...

    I just made a post here but was returned a message that the post must be approved by a moderator first. Why so? This is the first time I get this message when I have already made hundreds of posts.
