AiM RPM-ECU Coil Adapter – ARP03
The AiM RPM – ECU coil adapter is a filter that allows you to sample the RPM signal from the coil and the ECU, avoiding possible signal instabilities or wrong sampling due to electrical interferences that lead to voltage peaks or to an RPM signal whose square wave is not perfect.
The AiM adapter cleans the signal from undesired peaks and squares the signal waveform.
The adapter is helpful for ECU without CAN output.
Installation To Sample The Signal From The Coil
Connect the white cable labelled “RPM COIL 150-400V” to the coil earth trigger output.
Connect the blue cable labelled “RPM form” to the “RPM” output of the AiM device.
Connect the red cable labelled “V battery” to a switched 12V supply.
Connect the black cable labelled “GND” to a reference GND of the vehicle.
Installation To Sample The Signal From The ECU
Connect the blue cable labelled “RPM ECU 4-50V” to the ECU RPM output.
Connect the blue cable labelled “RPM form” to the AiM device “RPM” input.
Connect the red cable labelled “V battery” to a switched 12V supply.
Connect the black cable labelled “GND” to a reference GND of the vehicle.
