Don't have experience with the actual Bosch (or Toyota) units, but the
Lucas units used on Jags (more or less Bosch-under-licence) fire the
injectors every 360 engine degrees.  The V12s do this in 2 banks, with an
02 sensor per bank.  In this case one bank of injectors is fired every 3
sparks, not sure if the 6 cylinder units are in 2 banks or 1.

It seems to have the disadvantage that the injectors are fired twice as
often as needed, halving the pulse width, which cannot improve metering
accuracy at idle.
