ACCELERATION ENRICHMENT:
This changes the “accelerator pump” function of the fuel injection. Raising the number increases the amount of
fuel added when the pedal is pushed. Lowering the number decreases the amount of fuel added when the
pedal is pushed. It is highly recommended NOT to change this until the ECU is allowed to perform self-tuning.
FUEL PRIME:
Fuel prime is an option that is enabled by default in all
of the base calibrations. The fuel prime function injects
a small shot of fuel into the intake manifold when the
ignition is turned on, wetting the intake and allowing the
engine to start much quicker. The amount of fuel is
based on the engine temperature and how long it was
since the engine previously ran. This amount of fuel
can be increased or decreased by changing the
“Percent” value. If the engine seems flooded, reduce
this value. If the engine seems to want more fuel,
increase it. Experiment for best results.
NOTE: This only injects fuel once at key-on, and will not do it again until the engine has run. This fuel prime
occurs ½ of a second after key-on. If you quickly turn the ignition key without waiting for ½ a second,
the prime will not occur and it may take longer for the engine to start.
