## Early Motronic Ti Signal (Fuel Consumption)

Load Signal (Ti):
|
||||||
|
is produced by the ECM as an output function that represents the actual amount of fuel injected.
|
||||||
|
It is made available to other control modules as an input for operation.
|
||||||
|
|
||||||
|
These control modules include:
|
||||||
|
* OBC=Fuel consumption for MPG and Range.
|
||||||
|
* Instrument Cluster = MPG Gauge
|
||||||
|
* EGS = Load signal for shift points (If Equipped)
|
||||||
|
|
||||||
|
The Ti output is a processed square wave signal.
|
||||||
|
The frequency of the signal is proportional to engine RPM.
|
||||||
|
The pulse width and duty cycle will vary to reflect the injection quantity
|
||||||
|
|
||||||
|
It looks like it is a 12v signal as some have managed to get it working with it wired to inj1 running sequential mode on an MS.
|
||||||
|
12:53
|
||||||
|
Which also implies it is a 12v lowside to run it
|
||||||
|
|
||||||
|
you could actually run it with general purpose pwm pretty easily
