Anyone know what AFR the standard fuelling map on the 2010 GSA tries to meet
presume in closed loop, the ECU tries to run at 14.7, when the revs are up and larger throttle openings are being used, did BMW aim at 13.00 or lower to maximise power and torque or do the emission tests cover all revs
appreciate a low AFR ie slightly Rich setting will boost max torque whilst a slighter leaner setting will boost max bhp, so does the AFR vary across the rev range or does the emission laws not allow this luxury
would like some input to understand the readings I am getting on the autotune running 14.1 across the rev range compared to the standard setup
spec is no cat, no exhaust flap, shortened snorkel, PC5 with autotune and standard silencer
