[Diy_efi] Making a fake O2

[David Cooley]

If your injectors are starting to have reduced flow due to deposits, low
fuel pressure etc, the stock maps are NOT going to be safe.  The O2 sensor
is there to correct for changes in airflow/fuel flow etc in the engine to
keep the A/F where the manufacturer specified... If you take a vehicle that
isn't brand new, and run it in open loop with no corrections, then yes, the
open loop maps MAY cause damage.
