SOLO 2 DL
Our technicians and engineers are constantly working to improve both the firmware
(the application that manages your device) and the software (the application you in-
stall on your PC).
Each time a new firmware and/or software version is available the icon here above
appears with an arrow indicating that something is available for download (otherwise
the icon only shows the cloud).
Click it and freely download the new applications.
As said Solo 2 DL is sold with different additional cables. To receive RPM value from
the ECU you can use one of the available ECU connection cables.
If on the contrary your vehicle does not have an ECU you can sample RPM using the
RPM+external power cable.
To get the RPM from the ECU you only need to connect your Solo 2 DL to the ECU
and it will automatically sample that value.
Once the new firmware has been downloaded connect your device to the PC via Wi-
Fi to perform a firmware upgrade. In a few seconds the device is ready.
The output labelled “GRAY TACH” gives a 5-50V output that can be directly sampled
by Solo 2 DL.

13.1 RPM from ECU
If your vehicle has no ECU you need to have the kit including RPM+external power
cable to be connected to the 8 pins connector placed bottom right of Solo 2 DL.
This way Solo 2 DL can read the signal form 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 50 V).
The image below shows an example of wiring of the ignition system.
