I just had a look at the settings that I have in the Omex ECU on a standard Duratec with throttle bodies.
Ignition cut off is at 7,100 rpm and Fuel cut off is at 7,300 rpm.
The associated note says:
The whole Ign_Cut_RPM_Table should be set to the safety limit value unless ALS is in use.
The Fuel_Cut_RPM_Tableshould not be used for the safety limit and so should be disabled by setting the whole table to a higher value than the Ign_Cut_RPM_Table.
(ALS has to do with turbocharged systems)
