Wiring a reluctor (magnetic) type Motronic Sensor:
Positive wire (+): Connect to “Ground” on the Haltech flying wire harness or “Ground”
(which is Pin D, confusing but note the difference, one is an input as shown on the wiring
diagram and the other is a pin number on the plug) of the Trigger input plug of the fully
terminated harness.
Negative wire (-): Connect to "Trigger" on the Haltech flying wire harness (Pin B on the
Trigger input plug of the fully terminated harness).
Note: The polarity conflicts with Appendix E.2 as regards connection of a
reluctor adaptor. Due to hardware constraints of the E6X the polarity is in fact
reversed when connecting a reluctor type Motronic sensor.
The reversal of polarity is applicable only to the Trigger circuit. The Home
circuit polarity is not reversed.
In the main set-up page set the number of cylinders and set the system mode at the bottom of
the page to “Advanced”. Now go to the Ignition set-up page and under “Trigger Type” select
“Motronic”. As soon as you do the “Trigger Edge” option will disappear as the ECU will set
the correct edge.
Please note that the number of teeth entered in the software by means of the ignition set-
up page should be set to reflect the number of teeth that pass the sensor in one camshaft
revolution. For example, for a motronic wheel with 60 teeth less 2 missing teeth this
entry should be 120. The number of teeth should be directly divisible by the number of
cylinders. Further note that early versions of software such as 6.09 do not support motronic
type sensors of more than 60 teeth please contact Haltech as it is the intention to extend the
range of support in the future.
Set the “Trigger Input” to “Internal Reluctor” but only if the Motronic sensor is of the
reluctor type. If it is of the Hall effect type set “Trigger Input” to “Hall Effect”.
Set the “Trigger Gain” to suit. This number can be set between 0-7. A lower number will
make it less sensitive and a higher number will make it more sensitive. Start around 2 and
increase from there.
Please note that if you wish to use sequential type fuel injection a separate “Home” input
is required when using the Motronic type triggers. If the sensor delivering the home signal
is of the reluctor type it is not necessary to reverse the polarities ie
Positive would go to the “Home” (Pin E on terminated harnesses) and negative would go to
reluctor ground (PIN C on the terminated harness).
Wiring a Hall effect type Motronic sensor.
Hall effect type sensors have 3 wires, signal, power, and ground. Provide a power signal to
the power wire (must be switched ie no power when the ignition is off but do not connect to
an accessory line as power will disappear when the ignition key is turned), ground the ground
wire to a good grounding point, and the output wire should be connected to the Haltech
“Trigger Input” (Pin B on fully terminated harnesses). No in-line resistance is required for
Hall effect type Motronic sensors.
