3. First leave the engine off. Connect the cables and leave them on for a couple of minutes to
let the good battery charge the flat one.
4. Start the master car. End let it idle at 1500 RPM’s for at least 2 minutes. This will give the
alternator a change to bring both batteries up to 13.8V and put some charge in the flat
battery. If you don’t have thick jumper cables increase this time to 5 minutes.
5. Now start the other engine. If it does not crank easily, charge a little longer. If you engine
does not start, give ample time between cranking cycles to let the flat battery recover every
time.
8. Startup Procedure
8.1 Engine and system preparation.
Before you connect the ECU do the following:
1. Install new spark plugs on engines that were stored a long time.
2. Service and test the injectors to ensure they all have the same fuel delivery and that the filters
on them are clean.
3. First ensure that the installation is correct according to the Hardware Installation
procedure.
4. Test the electrical wiring a multi meter according to the Excel Test Procedure file provided on
the CD.
5. Power up the fuel pump by loosening the fuel pump positive from the relay circuit and
connecting it to 12V battery positive. Check the fuel pressure is around 3.5Bar and check for
fuel leaks. Reconnect to the relay.
8.2 Connecting the ECU for the first time
Now you can proceed with the following steps. If any steps do not correlate with the ECU
operation, stop and look for the faults. Ensure that the ECU is earthed!!!
1. Remove the coil and injector fuses.
2. Ensure that the Jumper Settings are correct inside the ECU.
3. Connect only the 12 way connector leaving the 10 way connector open. Switch the Ignition
on. Do not start the engine. The yellow LED on the ECU must come on. Also the green LED
on the Idle control board must come on if one is installed. If the yellow LED does not come
on switch off immediately as there may be a short on the 5Volt output that will damage the
ECU.
4. Ensure that the pins 1,4,6,7,8 &9 are broken out of the communications connector if you
are not using a Spitronics USB Converter cable.
5. Now switch the Ignition off and connect the Laptop to the unit. Switch it on again. Start the
PC software and connect to the ECU. The engine data like the water temp sensor should
be displayed. It should read more or less correctly for the cold engine.
6. Go through the setup page and ensure all the settings are correct for the engine.
Especially the Trigger Level Output. This setting may damage the ECU or coils if set
incorrectly!!!
7. Ensure that timing triggers from the distributor or crank are set up correctly. Also the Trigger
Levels, leading or trailing.
8. Check Rotor Fazing
it you have a distributor system. This will make Laptop interference is
set incorrectly.
9. Calibrate the TPS and Map sensors and save the calibration as described under active
sensors.
10. If you changed the RPM range or the Map sensor value, save the data to the ECU, close
the PC software and start it again. Then the new values for the graphs will be loaded to the
correct scaling.
