The Advanced Mode Features of the F9A
This is an upgraded version of the F9 with expanded capabilities in controlling and using
various engine accessories. The F9A can perform such functions as Turbo Waste Gate
control, Closed Loop Lambda control, etc.
If you have purchased an F9A, these extra options would already be available. Refer to the
F9A Section of this manual for instructions in using the extra functions.
If you have an F9 system, and would like to make use of the F9A’s abilities, you can
upgrade at any time without having to strip your vehicles wiring or purchase a new ECU. A
supplementary loom is included with the upgrade that provides connection to all auxiliary
circuits. Contact your Haltech dealer for information on how to get your system upgraded.
