Load Signal (Ti)

The "Ti" signal is produced by the DME ECM as an output function and represents the actual amount of fuel injected. It is made available to other control modules as an input for their operation. These control modules vary but can include OBC, Instrument Cluster, EML, EGS, etc.

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.
