The following guidelines will ensure proper operation the first time. Failure to install equipment
correctly may damage it or other equipment permanently. These failures will solely be the
responsibility of the installer and no guarantees will be given by us. Make sure you have read the
Terms and Conditions on the website www.spitronics.co.za before you install this ECU. By
installing the ECU you automatically agree to these conditions. All equipment is tested before it
leaves the factory. We accept no liability for malfunctioning of the equipment, or to injury that may
result from installation or the use of the equipment. We also accept no liability for costs of traveling
of transportation of the equipment or parts or vehicle recovery due to failures of any equipment.
Please read the instructions and drawing and make sure you understand before you begin.
2.1 Operator Safety
• Use only proper tools and products suited for auto installations. Sub standard products and
installation procedures may cause failure to the equipment having your customer break
down in dangerous areas.
• Use correct thickness of wire to carry the entire current requirement for that circuit. Too thin
wires will heat up and may start a fire causing injury.
• Use fuses to protect each circuit separately. Joint circuits require large fuses which may
heat and melt lesser circuits causing fires.
• Solder joints, and cover it with shrink sleeve to prevent loose connections which may cause
fires. Space solder-joints so that they do not sit next to each other minimizing the chance of
a short circuit.
2.2 Equipment Safety
• Never connect a TITAN ECU on the older EMU Hall cables without the cable modification.
See compatibility.
• If you have a firmware programmer, do not load Ver. E1 EMU firmware on the Ver. E2
TITAN ECU or visa-versa. It will damage the Micro because they are different.
• Never switch the power on, if the ECU enclosure is not grounded properly – this may
destroy some sensors.
• Never switch the power on with the coil connected. If the Trigger Level Output logic is set
wrong it may destroy the coil or driver. Leave the 10 way connector disconnected when you
switch the ECU on the first time. Then set the coil logic right, save the data and switch off.
Then connect the 10 way connecter and switch on. Ensure that the fuse is the minimum
required value. Too large fuse will not blow resulting in driver or coil destruction.
• Test the installation with the test procedure before connecting the ECU – this will prevent
damage due to faulty wiring.
• Connect the injectors to its own relay – other items will cause a voltage drop and result in
leaner mixtures.
• Connect the relay supplies directly to battery positive via a fuse as shown in the drawing –
otherwise voltage drops will still cause lean mixtures.
• Install the free-wheel Diodes on relays to prevent spikes from interfering with the ECU.
• Break out pins 1,4,6,7,8 & 9 on USB to RS232 converters and on serial cables. These pins
are used for other inputs and outputs of the ECU. It will hang the ECU and damage coils or
drivers. This does not apply to Spitronics USB converters.
• Make sure that relay pin numbers of the relay correspond with the drawing. A different relay
may damage the ECU.
• Check that coil connections are secure. Loose connections will damage the internal driver
Mosfets.
• Do not connect screen wires on the engine. The starter will draw current through then
melting the harness.
• The TPS must be connected correctly as it may damage the ECU or TPS permanently.
• Ensure that wires are kept away from hot or sharp parts in the engine. Also ensure that
engine movement does not put strain on the wires, as metal fatigue will break the wires in
time, resulting in ECU failure.
