The 320i is fairly reserved in its stock form, receiving the lower output N20B20. BMW report this to produce 184HP & 199TQ in stock form, with the higher output 245HP & 258TQ N20B20 saved for the 328i. This provides a small insight into the tuning potential from this engine!
As you already probably know, the F Series BMW ECUs are locked from the factory. Meaning you cannot typically ECU remap through the OBD2 port as was possible in the earlier E series vehicles. Luckily, at Regal Autosport we have all of the tools required in-house to unlock these ECUs so we can read the stock file, and install a performance ECU remap.
This particular car was an xDrive model which put our Mustang MD-500 AWD mechanically linked dyno to work to record power at the wheels, calculated flywheel torque, calculated flywheel power, lambda (fuelling) and boost.
