MoTeC Installation 27
Button Rotation
Button just leaving tower at TDC
The button must be a wide tip type to cater for a wide range of advance points
since the advance is changed electronically rather than mechanically.
Make sure that the button still overlaps the tower at the maximum advance
point.
The distributor should have no mechanical or vacuum advance as this is
provided by the ECU.
Spark Plug Leads
The spark plug leads should be high quality Inductive Suppression leads such
as Magnicor® leads and must be in good condition.
Do not use wire leads as they can cause interference.
Do not use resistive suppression leads as they will reduce the spark
energy.
Auxiliary Valves
The ECU can control various auxiliary valves such as Idle Speed or Turbo
Boost control valves.
Refer to the appropriate MoTeC drawing for setup and wiring details. Refer
also to any relevant Tech Notes.
ECU Mounting
The ECU should be mounted in an area where the internal temperature of the
ECU will not exceed 85 °C, generally this is in the passenger compartment.
Allow for adequate air circulation around the ECU. The ECU internal
temperature may be viewed using the E.M.P. Software or it may be recorded
using the data logging.
