TuneECU can basically be used only on models which are listed in the compatibility list.

last update November-19-2016
Support is only for the software (Android vers. only), no advice or recommendation
will be given on the use of maps. 
Except the brief descriptions available on the site,
no additional information will be provided on the maps, for any additional questions,  please ask in the appropriate forums.

Tests and Adjustments

This description was created for the Windows version of TuneECU and can be applied largely
on the Android version. Deviations in the Android version will be added here by and by.

                                      Triumph                                                                        Aprilia

KTM                                                                                    Benelli


Keihin Mode

In this mode, only 3 small dials of the dashboard are active, providing the value of the vacuum intake (Manifold Absolute Pressure) of the corresponding cylinder (Keihin only), thus providing  reference values for syncronising butterfly valve (throttle) opening.

Triumph: The display resolution is 10 hPa, the synchronization is correct if the difference is from 0 to 10 hPa.

KTM: here is the display resolution 1 hPa


Not all tests are available on all motorcycles.
Test components of the motorcycle.
Each test lasts around 10 seconds:

- (lower left column) Tests  certain components of the bike, the test takes about 10 seconds.

 Double-Click on each circle “   ”    to test:

How to KTM: After downloading a FI-map, start the engine and let runnig it idle (without touching accelerator) for 15 minutes, then turn it off.

How to KTM: After downloading a EP-map, Following a mapping download into the ECU, turn off the ignition (key) , turn on the ignition, slowly rotate the Throttle until full throttle then slowly close the throttle, turn off the ignition.

Adjusting the throttle cable
The idle speed control stepper motor will be completely retracted and the throttle valves completely closed.
Switch the ignition switch off, WITHOUT exiting or disconnecting the software, and adjust the throttle cable clearance.
No Yes No No
*** Warning: the metal part of the candle must be in contact with the mass of the bike under threat of destruction
     of the coil.

- Adjustments (Keihin except KTM):

 Adjusting exhaust butterfly  valve (EXBV)

 (See workshop manual), the 3rd dial displays the position of the valve (%) in this setting.

Adjust Idle Stepper Control Valve (ISCV) and TPS

Occurs in several steps (see workshop manual).


The 3rd dial displays the voltage of the TPS (Throttle Position Sensor) for adjusting its position.

Adaptation Reset (
formerly Reset TPS)

See the procedure in section "Map Edit".

KTM only Adjusting the throttle cable :
The idle speed control stepper motor will be completely retracted and the throttle valves completely closed.

Switch the ignition switch off, WITHOUT exiting or disconnecting the software, and adjust the throttle cable

- Adjusments SAGEM :
In this mode all readings of the instrument panel are inactive.
All other indication areas (sensors, test values, error code,  battery voltage) are activated.

TPS Reset

Resets the closed throttle position (sets to a high value). Then start the engine and let idle for 60s to allow the ECU
to trim to the correct value.

Setting CO

Double- click on the line to access this setting) for adjusting the idle fuel trim.

Long Term Fuel Trim

Double-click to adjust. (for models fitted with Lambda sensors only)

Idle Stepper

Double- click to "adjust IACV".

 It is possible to reset the last two parameters in the context menu available; right click on the arrows to adjust
 the setting (
this feature is available only in TuneECU for Windows).

Walbro ECU settings (Benelli TNT, Tornado 1130 & TREK)
Note: For the Walbro models is when using TuneECU for Android, still a converter cable,
            FTDI-USB-RS232 12V, required.

- Reset TPS: 
resets the closed position of the throttle.
- Idle Fuel Trim (CO): (
double click on the line to access this settinglets you adjust the fuel richness at idle.
- Global.Injection correction: Double click on "Global.Inj.correction" and adjust the parameters.
  (Recording in the ECU will be effective only after the value turns gray)
