• Ensure a proper earth between battery negative and chassis and also between battery
negative and the engine. Do not earth the engine on the body or the body on the engine.
• Do not put cutout switches from coil negative to ground as this may burn the coil
permanently. Rather break the supply line (Red Wire) through a switch so that the module
does not have power.
• Do not disconnect the battery while engine is running. The alternator will create high
voltage spikes which may damage the ECU permanently. Ensure that all connections from
the battery and alternator are secure. Also connect the alternator charge wire directly to
battery positive and not to the harness somewhere.
• Do not connect the ECU outputs directly to solenoids or fuel pumps. It is only strong
enough to pull in 2 x DC 12V relays. It can draw only 2A to ground.
• Test the coil resistance to see which type coil you are using and if it is still functional. This is
important to program the correct parameters. See Coil Selection. If you are not sure take it
to your agent for a free test, or start with the lowest Coil Time value namely 2 milliseconds.
• The trigger input may not be connected to coil negative. The high voltage spikes on coil
negative will damage the unit permanently.
• Make sure about the correct Jumper Settings before you switch the ignition on.
3. Requirements
3.1 Engine Requirements
We have to assume the vehicle you are using is either an existing electronic fuel injection model or
has been converted to fuel injection by the addition of a throttle body, fuel injectors and high
pressure fuel pump and filter.
You need to have the following components fitted: (Available from your agent)
• Fuel pump capable of a continuous pressure of 3.5 bar.
• Fuel pressure regulator.
• Fuel injectors matched to engine requirement.
• Throttle body with Throttle Position Sensor (TPS). (optional)
• Water temperature sender.
• A locked (no internal advance) distributor using either hall, magnetic or optical signal
generation or any Crank Trigger device.
• Good quality suppressed HT leads.
• Air temperature sensor (optional)
• Lambda sensor (optional)
• Idle valve or stepper motor (optional)
Notes on Ignition System
The ECU can be used for fuel control only, provided an ignition pulse output is supplied to the
ECU. This pulse must be a 12V to ground signal and may not be connected to coil negative. The
high voltage spikes on coil negative will damage the unit permanently. Connecting to an ignition
output is necessary to provide a signal for controlling the injector timing.
It can also be used for an advanced map-able ignition controller only. You can accomplish locking
a conventional distributor by either welding or bolting the weights together and disconnecting the
vacuum advance unit.
3.2 PC Requirements
• Pentium 4 Laptop
• Windows XP with service pack 2 or later
• Serial Port or USB device with USB to RS232 Converter (19200 baud rate)
• Screen Resolution 1024*768
• Ensure that the latest drivers for the PC are installed.
