MXL
can sample the RPM signal in different ways:
•
from the ECU via CAN bus or RS232;
•
from the ECU through a square wave signal (from 8 to 50 V);
•
from the coil: low voltage input (from 150 o 450 V).

2.4.2 – Pre-condition to sample the RPM in another way
To sample RPM signal from the ECU through a square wave signal or through the
coil it is necessary:
•
MXL Strada
+ kit basic sensors (optional – part number
X10MXLKS00000
;
draw code 04.554.02);
•
MXL Pista
standard kit;
•
MXL Pro05
+ 22 pins Deutsch type connector wiring (optional – part number

(optional – part number
V02554240
; draw code 04.554.20).

2.4.3 – Sampling the RPM from the ECU through a square wave signal
To sample the RPM from the ECU using a square wave, connect:
•
the white cable labelled “RPM” (
MXL Strada/Pista
) of the logger wiring to the
ECU RPM signal;
•
the blue cable labelled “RPM 8-50 V” of the 37 pins Deutsch type connector
wiring (
MXL Pro05
) to the ECU RPM signal.
Always refer to the ECU user manual for further information.
In case ECU output signal is not a steady square wave, an RPM adaptor (optional) is
needed. The images here below show a not square RPM signal on the left and a
filtered one on the right.
