1.2
The TITAN Engine Control Unit (ECU) was designed to be a cost effective replacement for high
tech fuel managements systems. It uses unique features found in high tech systems, although it is
still easy to install and program. It is designed with the novice and professional installer in mind.
See the ECU Control Philosophy
TITAN is a South African made product and can be customized for dedicated engines and models.
It can also be combined to form larger complex systems for racing applications. It is a reliable
compact system which is easy to mount in the driver's compartment. No external firing modules or
converter boards are necessary.
The ECU is customized for specific applications and the installer does not have to pay for excess
wires or unused features. Nor does he have to buy separate firing modules and MAP sensors
which will increase the price. Instead it is compiled with the correct harness and equipment as well
as software and maps to ease installation and setup. The software will also be calibrated for the
sensors of the specific engine.
This ECU comes in three models with standard harnesses to accommodate most engine
requirements namely Standard, Intermediate and Advanced units. The units are designed to be
small and compact and use the latest in high speed micro controllers with surface mount
technology. These units are machine soldered to minimize human error.
Firing modules that will reduce cost are incorporated in the ECU. Analog idle control is included on
board for one and two wire idle valves. External Stepper idle control units can be connected with
all three types of ECU's.
The PC Tuning software is standard for all units. The specific ECU will blank out all tuning fields
not applicable.
Other key features are variable charge times which are MAP (Mean Absolute Pressure)
dependant, fuel cut-off features, launch control, lambda loop control, general purpose outputs,
altitude correction etc.
The different models are as follows:
TITAN Standard
This is the most basic and cost effective form of the ECU. It is a single channel trigger,
(Magnetic or Hall input,) one coil output and two batch injector outputs. The injectors are
pulsed 180° out of phase. This ECU is suitable for cars with a distributor and single coil.
Engines such as 3,4,5,6 and 8 cylinders can be used. For 12 cylinders the intermediate
ECU is recommended for more injector outputs. Electronic distributors do not need to be
modified for fazing. Idle control and launch control is standard.
TITAN Intermediate
This ECU is for more complicated trigger setups in distributors like Toyota 24T+TDC,
Nissan Optic, all crank gears, and customized optic disks etc... It does Split-Sequential
fueling on 4, 6, and 8 cylinder injector banks. It has one coil output. Idle control and launch
control is standard.
TITAN Advanced
This ECU is designed as the intermediate but with the added feature of multi coil or wasted
spark. The ECU has 6 trigger outputs which can be used for different combinations of
further in the manual to understand how it works.
