10.1.14 Engine lack power, idle erratic, or runs lean
1. The fuel pressure is erratic. This may be due to the pump sucking air on the in feed which
causes cavitations and loss of pressure. This happens more frequent when the engine is
hot.
2. Injector positive is wired incorrectly. It does not have its own supply direct from the battery
via relay 1.
3. Incorrect setting of fuel maps.
4. Fuel pressure or flow rate to low. Dirty fuel filter.
5. Faulty fuel pump.
10.1.15 ECU cuts during driving – Interference
Interference or feedback is caused by the following reasons:
1. Earth wires incorrect. Tie the black wires of the harness to the ECU enclosure. Tie a 2.5mm
or thicker wire from the ECU enclosure to the body as an earth strap if it is not screwed
directly onto the body.
2. Screened cables of the sensors must be connected close to the sensors to ensure
maximum screening.
3. No screen wire must be connected to the engine. Only to the TPS, Map sensor
Temperature sensors and lambda sensor if specified by the drawing. Don't common it with
engine ground.
4. Faulty High Tension sparkplug wires.
5. HT lead run too close to sensitive input wires.
6. The Ignition Positive wire is used for high current devices that generate voltage spikes.
Couple all coils etc via relay circuits from the fuse box supplied.
7. Poor voltage supply to the ECU.
8. Large relays do not have decoupling diodes and induce spikes on the ignition wire. Install
free running diode supplied according to drawings.
9. Incorrect alternator wiring. The main charge wire (thick positive) should be connected at the
battery positive terminal rather than the vehicle harness. The battery acts as the smoothing
capacitor.
10. Battery earth straps are not adequate. Earth straps should go from the battery negative to
the body and also from the battery negative to the engine.
11. Incorrect rotor fazing. The spark has to jump a gap in the distributor inducing spikes on the
pickup device.
