Wideband Air/Fuel Ratio Monitors

Is "Lean-OK-Rich" enough information for your turbocharged application? When the accuracy of your air-fuel ratio is critical, don't rely on an old-fashioned single-wire oxygen sensor. Engine tuners have found that only modern wideband sensors are sensitive enough for fine-tuning fuel injection or forced induction.
