CLEAR FLOOD
If a flood condition occurs, turn the key on then press the accelerator to wide-open throttle. This tells
the ECU to turn off the injectors. Crank the engine to clear the flood condition until the engine starts
(release the throttle open start-up).
Note: The TPS is self calibrating so the key must be in the On position prior to pressing the accelerator.
DIAGNOSTICS
There is a self-diagnosing system built into the Atomic EFI. Each
covered parameter can show a status in one of three ways.
“OK”: the parameter is functioning normally.
“Error C”: there is currently an error occurring.
“Error H”: there was previously an error that has been remediated
within the last ten ignition cycles.
