There is one AFC that is made for German cars. U can check it up in sunway area. Last time i saw it. Not sure if Motorsports Division have them but i know one of the shops there carry them.

Yup, it's call the SAFC Select by Apexi.

I have one for FS.

PM me.

suitable for all models @ which model?

 

[Daniel]

Depends.
It's didn't work for what i wanted it to do.

But it's monitoring capabilities is quite nice.

Please also note that it's not a true piggyback system. It is just a fuel 'controller' where it allows the tuner to fine tune the fuel to obtain a nicer AFR, that's all it will do.

Bro, best not to set any expectations for performance gains. Most likely on a standard BMW it won't do ANYTHING for performance... apart from adding some disco lights to the dash. In fact may cause power loss or engine management errors.

Piggybacks do have a use, but on a respectably modded car you'd want more than an AFC anyway, or nothing at all.

piggybacks are fine for WOT, but under closed loop, the ecu will re-learn.

go for chip or flash upgrade better. or just get a standalone ecu.
