The FI system on the test vehicle (not a road going vehicle) was an after market
unit and O2 feedback was not being used on it.  We were able to set the AFR for
a variety of throttle/load/speed settings, including light loads, not just
significant loads.  A good way to get your initial FI computer map settings.
