caleb_5375,

Previous owner install with AFC 5 button & sard fuel regulator. But he took it out. So I think my A/F setting gone.

I heard that the BT ECU is a self-learning ECU. Right? Will it tune back itself or I need to install a standalone ECU?

fuel just running rich. Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. check for faulty equipment

i read an article regarding this issue but forgot where. it seems must check so called O2 sensor (i don know either correct name or not but it's sensor with attach at exhaust) at exhaust bcoz it'll determine the fuel ratio in smoke which going through the exhaust. it'll send the signal to ecu to self programming on the correct fuel ratio.
