MSD distributor and crank trigger:
The distributors are equipped with VR/magnectic sensors e must be
wired as the following:
•
Orange/black: connected to the red wire of 2-way shielded cable
of FT500/FT500LITE
• Purple/black: connected to the white wire of 2-way shielded
cable of FT500/FT500LITE
Any mechanical or centrifugal advance must be locked
The crank trigger kits have different wire colors and the wiring must
be as following:
• Purple: connected to the red wire of 2-way shielded cable of
FT500/FT500LITE;
• Green: connected to the white wire of 2-way shielded cable of
FT500/FT500LITE
The RPM signal settings must be:
• 4 cylinders: 2 (at crank) or 4 (at cam);
• 6 cylinders: 3 (at crank) or 6 (at cam);
• 4 cylinders: 4 (at crank) or 8 (at cam);
RPM sensor:
VR differential, rising edge, crank index position 45º (need to calibrate
ignition with timing light)
Cam sync sensor:
Not utilized, unless you are running crank trigger and distributor
(or a dedicated cam sync sensor) with a single tooth.
60-2 Trigger Wheel Aligned on the 15th tooth after the gap
Sometimes a trigger wheel has to be fabricated because of the type
or size used, as it happens with motorcycles, for example. In such
cases, it is important to observe that the size of the teeth on the
fabricated trigger wheel must be equal to the size of the space in
between them. The minimum diameter for the fabrication of a 60-2
trigger wheel is 125mm (5”).
48-2, 30-2, 30-1, 24-2, 24-1, 15-2, 12-3, 12-2, 12-1, 12+1
and 4+1 teeth:
These are less common types, but they are perfectly
compatible. These trigger wheels can operate without a camshaft
position sensor, as they have a gap that indicates the TDC on cylinder 1.
In order to correctly inform the engine position to the injection module,
it is necessary that the injection has the right information about the
alignment of the trigger wheel in relation to the TDC on cylinder 1.
The image below shows a 60-2 trigger wheel with the sensor aligned
on the 15th tooth after gap. In this image, for example, the engine
is on the TDC on cylinder 1. Notice that the RPM is clockwise, and
therefore, the TDC on cylinder 1 is set 15 teeth after the sensor passes
the gap. That is exactly the number of teeth that must be informed to
the injection upon its configuration.
