Haltech F9A - Manual (Page 79)

Introduction
This section provides information only on the operation and use of the
options that are available with the F9A system.
The previous section of the manual relates to the Haltech
™ F9, which explains in detail the
fitting and programming of the system.
The F9A executes the fuel delivery in the same manner as the standard F9. However, the F9A
incorporates a number of auxiliary outputs which can control various devices. In total, there
are five options that can be selected: idle speed control and closed loop lambda control (when
the optional idle air control motor and oxygen sensor, respectively, are installed), plus three
auxiliary outputs that may be programmed from a list of functions.
All these options and their parameters are set through the F9 programming software.
There is only one version of the programming software that is used for both F9 and F9A
systems. The ability of your system to operate the extra functions described in this
manual is determined by the number of parameters within the hardware of the ECU.
When Online, the F9 programming software will only allow options to be enabled as the
ECU permits. Maps that are generated and saved while in Offline mode will not
automatically enable options if later loaded when Online. If you are unsure of your
system’s capabilities, contact your Haltech
™ dealer.
You are well advised to complete installation and programming of the base injection system,
as much as possible, before attempting to run the accessories of the F9A. This should give
you time to familiarise yourself with the operation of the Haltech
™ software, and give you a
running engine to work with. Even if you want to run Turbo Wastegate Control, don’t enable
the option until you have the car started and driving (albeit with rather low boost levels).
Remember that options may be individually enabled and disabled, as you please, to make
programming straightforward.
If you have purchased an F9 system with no options available, do not be concerned
about retro-fitting the options you want. We have made the upgrade to the F9A as
simple as possible. There is no need to strip you vehicle’s wiring, nor to trade-in your ECU.
The F9A’s options run through a supplementary loom that is quite separate from the main
loom, and any additional wiring required is minimal. The F9 programming software you
received with your original system can be used to programme the new options the F9A
delivers

. If you have an older F9 unit, newer functions may not be available with your
version of firmware. Contact your Haltech
™ dealer to see if you need an upgrade to your
firmware to run the functions you want.
