The following items should be taken into account when choosing a location for the ECU:
1.The G4X ECU requires environmental protection for both physical and electrical factors that may affect its performance. Normally this requires the device to be fitted inside the vehicle cabin. This position avoids the high temperatures associated with the engine bay and reduces the chances of the ECU getting wet. This position also offers some physical separation between the ECU and ignition components that may cause interference.
2.The main exception to this rule is where the engine is somewhat distant from the driving position, such as a boat. In these cases the ECU should be mounted in close proximity to the engine but NOT directly on, or next to, the engine (e.g. mounted just outside the engine compartment). The idea here is to minimise the length of wiring between the engine and the ECU while maintaining some physical distance to prevent heat and interference. It is preferable to have short main wiring and a longer tuning cable.
3.If water immersion or spray is likely (particularly for marine applications), additional protection may be necessary. A sealed plastic container may be employed here.
4.Allow sufficient space at both ends of ECU for the main wiring harness and tuning cables to be connected.
5.A mounting bracket is provided. Install the bracket on a flat surface and clip the ECU into this bracket firmly. Use only the mounting bracket provided and DO NOT drill holes in the case, as this will probably cause internal damage.
6.It is recommended that the ECU is rubber mounted in order to isolate the ECU from vibration.
7.For motorsport applications, the ECU should be located in a position that minimises the risk of physical damage in the event of the vehicle being involved in a crash. ECUs used for speedway applications should be mounted securely within the cockpit area, protected from the elements, isolated from vibration and utilise an additional retention strap for protection from high impacts.
