DIGITAL ECU TUNER 3 – User Manual
Controlling the ignition angle
The device includes options to control ignition in the ignition systems listed below:
1) retard / advance of the signal from the toothed wheel 60-2,
2) retard / advance of the signal from the toothed wheel 36-2,
3) retard / advance of the signal from the toothed wheel 36-1,
4) retard / advance of the multitooth signal,
5) retard / advance of the SAW signal which controls EDIS module,
6) retard / advance signal from toothed wheel Subaru GT ( 6 teeth),
7) retard / advance signal from toothed wheel 12+1 (Honda D series),
8) retard / advance signal from toothed wheel 18-2-18-2 (Nissan QG18DE),
9) retard of a single signal controlling the ignition module,
10) retard of two signals controlling dual ignition modules,
11) retard of a single regular signal,
The device has an advanced ignition input (Ignition #1 In), with configurable functionality. Thanks to that option,
one input can serve both signals: the VR and Hall’s/ optical sensors.
Input mode of Ignition #1 In
Description
VR Sensor adaptive threshold Input mode, which serves VR sensors. Thanks to the signal true zero cross
detection and the adaptive hysteresis, this input mode is very noise immune.
VR Sensor fixed threshold
This mode is used to serve VR sensors using true zero cross detection and
hysteresis at the 200mV level.
Hall effect or optical sensor
This mode serves optical and Hall’s sensors. The signal’s amplitude is required to
be higher than 2.5V.
Other sensors
This mode serves other inductive and Hall’s sensors without hysteresis.
The device has 3 ignition outputs:
1)
Ignition Out
(Pin 6) – used for the unipolar signals,
2)
Bipolar Ignition Out (
Pin 5
) -
used for the bipolar, unbalanced signals (
single ended
),
3)
Bipolar Ignition Out Inverted (
Pin 4) – complementary signal for the signal from the output Bipolar
Ignition Out used for bipolar, balanced signals (
differential
),
Attention !
Connecting ignition outputs directly to the ground , +12V or directly to the ignition coil
will damage the device!
