7.9.10 Flooded engine conditions.

When the engine speed is below 450 r.p.m. and WOT is de-

tected the ECU will reduce the base map injection durations

by 40% and ignore all cold and post-start corrections in an

attempt to prevent further flooding.

Under full load operation the engine is required to deliver

maximum power and requires a richer A/F ratio. This condi-

tion is detected when the engine speed is above 450 r.p.m.

and WOT is selected allowing the ECU to increase the base

map injection duration by a given factor to ensure maximum

power delivery.
