EVO4S

6. RPM

EVO4S can receive the RPM signal from three different sources:

from ECU

through a square wave signal (8 to 50 V)

from the low voltage (from 150 to 400 V) of the coil

6.1 RPM from ECU

To get RPM from the ECU please configure your EVO4S and enable RPM channel as explained
in section 10.1. RPM is one of the many data flowing from your ECU to EVO4S.

6.2 RPM via a 5-50 V Square Wave Signal or coil (150-400 V)

In case your engine is not managed by any ECU, EVO4S can read the signal from the low voltage 
of the coil (whose peak can be from 150 to 400 V) or from a possible square wave (the peak
can be from 5 to 50V). The pin labelled 

"RPM"

reported in appendix 

“Pinout” 

receives the

signal.

The image shows an example of wiring for
the ignition system.   

The output, labelled 

“GRAY TACH”

gives a

5-50V output that can be directly acquired
from EVO4S. If the output is not available
from the ignition system, the system has
to be connected to the low voltage of the
coil, as shown in the following schematic.

Point 1

: Low voltage of the coil

Point 2

: Connected to the spark plug

Point 3

: Connected to the +12V of the 

battery

After connecting the RPM signal, please use
the software RaceStudio3 for enabling the
RPM channel, as explained in section 10.1.1
