The X-Gauge is now finally available for the smart® fortwo cdi with the diesel engine.
Note, however, that a cdi will have to be of model year 2004 or higher in order to be
compatible with the X-Gauge. Unfortunately, the ECUs in earlier cdi models do not deliver
any generic engine parameters through their OBD-interface.
The cdi specific X-Gauge will display the following parameters:
- Time
- Date
- Battery Voltage [V]
- Inside Temperature [ºC, ºF]
- Number of Trouble Codes
- Calculated Load Value [%]
- Engine Coolant Temperature [ºC, ºF]
- Intake Pressure [bar, psi]
- Engine RPM [rpm]
- Vehicle Speed [km/h, mph]
- Intake Air Temperature [ºC, ºF]
- Current Mileage [l/100km, mpg]
- Average Mileage [l/100km, mpg]
- Maximum Vehicle Speed [km/h, mph]
- Acceleration [s]
- Maximum Acceleration [s]
- Turbo Cool-Down Time [s]
It will also display and clear Confirmed and Pending diagnostic trouble codes (DTC).
The cdi version of the X-Gauge firmware will even show you a cdi logo next to
the picture of a smart fortwo during the startup animation.

Software version 1.70, to be delivered immediately, is now capable of displaying
Confirmed as well as Pending
diagnostic trouble codes (DTCs).
Confirmed codes indicate serious problems that the ECU has detected over 2 driving cycles
(driving cycle: start engine - drive - stop engine). Confirmed codes will also turn on the
check-engine light in the lower right corner of your instrument panel. Pending codes indicate
problems that the ECU has detected during the current or last driving cycle and are not considered
serious yet, so pending codes will not turn on the check-engine light. A pending code
will turn into a confirmed one if it has been detected over more than 1 driving cycle.
The X-Gauge continuously displays confirmed and pending codes alternatively.
Read about this new feature in the latest version of the
user manual (page 20).

Software version 1.6, the one that will be delivered immediately, adds the
following 2 user configurable settings with regards to display orientation:
- Vertical Flip: Yes/No
These settings were added in order to give more flexibility for non-standard X-Gauge installations (enabling both with 'Yes', for instance, will rotate the display by 180 degrees).
See the description of this new feature in the latest version of the user manual.

It has been verified now that the X-Gauge is fully compatible with the
smart® roadster !
A special software version is now available that shows the picture of a roadster instead of
a fortwo during the X-Gauge's startup animation.
For the roadster, however, you have to come up with your own solution for housing and wiring.
