Just as the Cruise Air/Fuel target can be adjusted for fuel economy, the WOT Air/Fuel target
can be adjusted for maximum power. It is quite possible that the engine can make more power
at an air/fuel ratio that is leaner (higher number) than the preloaded WOT Air/Fuel target. Or it
might prefer a richer (lower number) air/fuel ratio. This is less likely, but it all depends on the
engine.
Remember that an air/fuel ratio that is too lean (higher number) can cause severe engine
damage – especially at WOT!
When changing any of the targets to a leaner value, do so in
small increments and pay close attention for any signs of detonation, etc.
Additional information for E85
Due to the unique properties of E85, different air/fuel ratios are used with that fuel. E85 air/fuel ratios
will be numerically lower. Multiplying a gasoline air/fuel ratio by 0.68 gives a good approximation of
the equivalent E85 air/fuel ratio.
85 / / 0.68
For example, if an engine likes to idle at 13.5:1 air/fuel ratio on gasoline, it should like somewhere
around a 9.2:1 air/fuel ratio when running on E85.
Enrichment Fuel
Accel Fuel
When the throttle is opened quickly, the engine needs an extra dose of fuel for smooth operation. In
electronic fuel injection, this is commonly referred to as Acceleration Enrichment or Accel Fuel. It is
very similar to the accelerator pump on a carburetor. The ECU is preloaded with typical settings for
Accel Fuel. This feature allows you to adjust those settings for more or less Accel Fuel by selecting a
positive or negative adjustment factor. Selecting zero leaves the ECU to use the preloaded values.
