MoTeC Hydrospace S4 Installation 27
Installation
The M400 Marine ECU replaces the factory ECU on a mounting plate beside
the engine.
Remove the factory ECU (3 x M4 bolts) and drill 6 holes into the existing
mounting plate using the mounting plate template. The template is supplied
on a 1:1 scale and can also be downloaded from motec.com.au (CDS13044-A
Hydrospace S4 Mounting Plate Template).
Fit the supplied Ignition Module to the mounting plate.
Note: This module generates significant heat and requires the use of
dielectric grease between the module and mounting plate to ensure proper
heat transfer. Firm fixing of the mounting bolts is also necessary for proper
heat transfer.
Then, place the rubber backing pad on the plate and secure the M400 Marine
ECU with the Mounting bracket using two M6x16 stainless steel cap screws
and two M6 Nylock nuts.
Finally, connect the adaptor loom harness between the M400 ECU and the
factory wiring harness.
The entire assembly can now be lowered into position beside the engine, and
fixed into place with two M6 lock nuts.
