Introduction
The VSpeak ECU Converter provides the data of the Swiwin ECU on the telemetry system of
your remote control system.
The ECU Converter calculates the fuel consumption and also transmits it to the respective
transmitter of the model pilot.
Settings of the VSpeak converter can be made directly from the transmitter for Jeti, HoTT and
PowerBox, for all other RC systems with the aid of a Micro SD card.
Always follow the settings for Failsafe (section 1.1 Connection diagram / Failsafe).
The VSpeak ECU Converter can be software-updated by the user.

1Hardware
Data LED: green(flashing) →receiving data from the Swiwin ECU and data transfer to the
receiver (at Jeti Sensor only then, if JetiBox buttons are activated)
red (flashing) →no data from ECU–but the connection to the telemetry System
is well
The blue LED is blinking every second to signal the normal function of the ECU Converter.
Use the blue UNI servo plug to connect to the Swiwin ECU pin header labeled TELEMETRY.
The black single-pole UNI servo plug is plugged into the receiver on the throttle channel.
With the Futaba S.Bus2, Jeti EX Bus and Powerbox P²Bus the connection has no function, the
throttle value is transmitted via the respective telemetry bus.
The connection between the VSpeak ECU converter and the remote control system is made
with the 3-pin servo patch cable except in the case of Spektrum, there with the special cable
(see following pictures).
The attachment of the VSpeak ECU converterin the model can be done with velcro tape, double
sided tape or cable ties.

1.1 Connection diagram / Failsafe
As can be seen in the following graphics, the VSpeak ECU converter
must be connected between the receiver and the Swiwin ECU. The
throttle signal from the receiver and the telemetry data are
transmitted via the 3-pin servo cable with the blue UNI servo plug.
Set on the ECU:
[BUS]ThrottleCha: 3
TelemetryMode: 1/1
… and the required time for
FailSafeTime:
1.1.1 Jeti Duplex Sensor, Multiplex, HoTT, FrSKY and JR PROPO
For the receiver throttle output Failsafe must be set to no signal. The time until failsafe should
be set to 0 in the remote control system; the FailSafeTime that can be set in the ECU then
applies.
If it is not possible to set "no signal" for FailSafe, then at least Throttle Min should be output
for FailSafe, i.e. -> Turbine Stop (here, of course, set the time until Failsafe in the remote control
system accordingly).
1.1.2 Spektrum
The only difference with Spektrum is the special 4-pin telemetry cable instead of the 3-pin UNI
patch cable - the same applies to FailSafe as described under 1.0.1.
1.1.3 Jeti EX-Bus, Futaba S.Bus2, Powerbox P²Bus
With these systems, the throttle signal is transmitted via the respective telemetry bus, so that
the 1-pin Throttle cable of the VSpeak has no function and is not connected.
Failsafe is transmitted from the telemetry bus to the ECU converter, any settings in the remote
control system have no effect here - only the FailSafeTime in the ECU is effective.

2Telemetry
The voltage for the VSpeak ECU Converter is supplied by the receiver.
The Button of the ECU Converter can be used to switch between the systems Jeti Duplex,
Multiplex, HoTT, Futaba, FrSky, JR PROPO, PowerBox and Spektrum, s. section 2.0.
2.0 Selection of the telemetry system / Parameter file "SWIWIN.TXT"
When you turn on the Telemetry System is signaled by a LED for a period of 3 seconds. While
the blue LED flickers, the STATUS LED shows the chosen telemetry system:
green Jeti Duplex EX (s. section 2.1)
red Multiplex (s. section 2.2)
green (flickering) HoTT (s. section 2.3)
red (flickering) Futaba S.BUS2 (s. section 2.4)
red (flashing) Futaba S.BUS2 V10 (s. section 2.5)
green (flashing) FrSky S.Port (s. section 2.6)
red/green (flashing) JR PROPO (s. section 2.7)
red/red/green (flashing) PowerBox (s. section 2.8)
red Spektrum (s. section 2.9)
Double-click on the Button (similar to the double click of a computer mouse), the telemetry
system can be switched.
To preserve safety during the selection of the telemetry system, the ECU Converter does not
transmit any information until a restart.
The setting is saved.
Parameter file „SWIWIN.TXT“
With the remote control systems Jeti Duplex, HoTT and PowerBox the parameterization can be
done directly at the transmitter, for all other systems the parameter change can be made via the
file „SWIWIN.TXT“.
By inserting an SD card (without file "SWIWIN.TXT") into the Micro SD card slot of the ECU
converter and switching on the converter, the converter recreates the file "SWIWIN.TXT" with
the parameters currently set in the converter. Now you can look at the parameters in the "set
value" column of the "SWIWIN.TXT" file using an editor (Windows Accessories / Editor) and
change the values. The parameters are largely self-explanatory, the permissible value range is
in the "value range" specified. To change the parameters in the ECU converter, the modified
"SWIWIN.TXT" file is now reinserted into the SD card slot and the converter is switched on.
The Data LED green/red signals the status of the Read/Write process of the SD card:
red flashing: Card not readable by the ECU converter
green flashing: Writing / reading the parameter file "SWIWIN.TXT" -> OK
green/red flashing: Parameter transfer of "SWIWIN.TXT" incorrect
With green / red flashing, not all parameter changes have been accepted in the ECU converter,
e.g. because of invalid characters or values outside the range "value range". The ECU converter
then re-created the "SWIWIN.TXT" file with the data currently stored in the converter. You
should look at it again in the editor and compare it with the parameter changes you have in
mind.

ECU converter Swiwin Version: 1.0 www.VSpeak-modell.de Page 7/43
The values in the areas "general" and
"alarms" are applicable for all remote
control systems:
-> global parameters (see next page).
The other sections in the file
"SWIWIN.TXT" are related to the
particular remote control system and
have their meaning only there.
Note Parameter change:
Do not delete lines and do not add any
lines.
Override the parameters instead of
inserting characters.
Only the area "set value" is
authoritative.

Global parameters
general
FuelFlow @2.5V/@4.0V Fuel tanksize
The VSpeak ECU converter can calculate the current FuelFlow and the fuel
consumption on the basis of the ECU pump voltage. The necessary parameters can
be adjusted here, as flow values in ml / min at each 2.5V and 4.0V pump voltage.
Tips for determining the fuel flow rate can be found in the appendix of these
operating instructions.
Fuel tanksize is the capacity of the main tank in ml.
FUEL rounded
The display accuracy of FUEL (ml) can be set here.
Rounding the display makes sense, when using speech to reduce the announcement
syllables.
Taxi Tank
For models where a taxi tank is plugged into the main tank until the model is lifted
off, set "Taxi Tank = ON". If the turbine is in the "Running" status, then when
THROTTLE = 80% is exceeded for the second time, the FUEL will "reset", ie the
displayed FUEL is only once set to "full" (the value set at "Fuel tanksize") again at
this time.
Throttle Offset
The Throttle Offset is used to adapt the throttle display to the RC display on the
Swiwin GSU.
When delivered, this is set to 0%, the entire throttle range is displayed, ...
starting with 0% Min (Stick Min, Trim Low)
over ~10% Idle (Stick Min, Trim Max)
up till 100% Max (Stick Max, Trim Max)
Set the throttle value here as an offset that is displayed when you are idle.
From now on the Min ... Idle area is "hidden", 0 ... 100% then corresponds to Idle ... Max.
RPM factor
The actual turbine speed is the displayed value multiplied by the parameter RPM factor.
Throttle->ECU
Here you can set the servo channel via which the throttle
signal is transmitted from the VSpeak converter to the
ECU.
Throttle->ECU and [BUS]ThrottleCha
must match.
alarms
The parameters are largely self-explanatory, lower values as "low" thresholds and
exceeding of the "high" thresholds trigger alarms, with "OFF" the respective alarm
is deactivated.
The "low..." alarms are activated after at first exceeding the "Low ..." alarm
threshold. The low RPM alarm ends at PUMP = 0.000V, which means that these
alarm is suitable for signaling a turbine flameout.

ECU converter Swiwin Version: 1.0 www.VSpeak-modell.de Page 9/43
2.1 Jeti Duplex EX
The VSpeak ECU converter supports the two Jeti telemetry protocols Jeti EX Sensor and Jeti
EX Bus.
In the delivery condition and after every change of the telemetry system (see section 2.0) the
Jeti EX Sensor is always activated. This means that the VSpeak ECU converter can work with
every Jeti receivers can be connected to the Ext port (this receiver port is always set to
JETIBOX/Sensor on delivery) - otherwise the relevant port would have to be set to
JETIBOX/Sensor or Telemetry Input.
Using the Jetibox (... - emulation in the Jeti DC/DS transmitter) the protocol in the VSpeak
ECU converter can be switched to Jeti EX Bus. The change of the telemetry protocol is only
effective after restarting the VSpeak ECU converter. The EX Bus must also be set on the
relevant Jeti receiver port.
The main differences in the use of the two Jeti protocols are (see section 1.1.3),
that with Jeti EX Bus the throttle channel is also transmitted via EX Bus,
the black, single-pole UNI servo plug (throttle channel) is therefore without function, and
no special Failsafe settings need to be made for the receiver throttle channel
With the Jeti EX Sensor, the connection and the setting of Failsafe are accordingly
section 1.1.1.
The following chapters apply equally to both protocols.

Alarms
Irrespective of the possibility to program alarm thresholds for the "EX" values in Jeti
transmitters the VSpeak ECU Converter has the ability to set alarms (by using alarm codes) that
are ECU status depending. These alarms can also be announced by the Profibox as voice
messages.
As can be seen in the table, the alarms for F-RES and RPM can be switched OFF, if no alarm
is to be given at BATT and EGT, the alarm thresholds can be set to "inaccessible" values.
Permanently pending alarms, e.g. FUEL or BATT, max. 3 times repeated.
FUEL
The alarm Fuel is signaled when the fuel rest is lower than the F-RES set value.
BATT
The alarm BATT is signaled when the battery voltage is lower than the BATT set value.
RPM (turbine)
The alarm RPM is signaled when the turbine rotation speed is lower than the RPM threshold
value.
The speed monitoring is started after at first exceeding RPM alarm threshold and ends with
Pump = 0.000V
The RPM alarm is suitable for signaling a "turbine flameout".
EGT
The alarm EGT is signaled if the temperature exceeds the value set at EGT.
F-Flow / Pump-V @ 2.5V respectively 4.0V
FUEL-Flow are the two parameters for the current fuel flow at 2.5V or 4.0V pump voltage.
The two parameters can be determined with the help of a flow meter - or, if you don't have one
at hand, in the following way: You can run the turbine with 2.5 or 4.0V pump voltage for a
period of 1 minute and measure it fuel used. A more precise result can be obtained by carrying
out the measurement over several minutes and dividing the amount of fuel consumed by the
number of minutes (see appendix).
FUEL Tank Size
Volume of the main tank in ml.
FUEL rounded
The display accuracy of FUEL (ml) can be set here.
Rounding the display makes sense, when using speech to reduce the announcement syllables.
Taxi Tank
For models where a taxi tank is plugged into the main tank until the model is lifted off, activate
"Taxi Tank ". With "Tank Size" the tank volume of the main tank has to be set. If the turbine is
in the "Running" status, then when THROTTLE = 80% is exceeded for the second time, the
FUEL will "reset", i.e. the displayed FUEL is only once set to "full" (the value set at "Tank
Size") again at this time.

Throttle
Offset
The Throttle Offset is used to adapt the throttle display to the RC display on the Swiwin
GSU.
When delivered, this is set to 0%, the entire throttle range is displayed, ...
starting with 0% Min (Stick Min, Trim Low)
over ~10% Idle (Stick Min, Trim Max)
up till 100% Max (Stick Max, Trim Max)
Set the throttle value here as an offset that is displayed when you are idle.
From now on the Min ... Idle area is "hidden", 0 ... 100% then corresponds to Idle ... Max.
Servo (…only Jeti Telemetry "EX-Bus" )
Selection of the Jeti-Servo channel via which the throttle signal is transmitted to the VSpeak
ECU converter via the Jeti EX-Bus.

For the values indicated in the above table with "Alarm", alarm thresholds can be set with the
aid of a Micro SD card and the parameter file "SWIWIN.TXT". Furthermore, the MSB
addresses can be set as desired - a double address assignment within the ECU converter is
excluded.

2.2.3 Turbine status
To display the turbine status, texts are stored in the multiplex transmitters as well as in the
"gooseneck" telemetry display.
These do not 1 : 1 correspond to the status messages of the Swiwin ECU.

2.3 Graupner HoTT
Using the HoTT System there are 2 ways to transmit telemetry data, on the one hand as "text"
and on the other hand only the pure values.
Using text mode it is possible to establish a bi-directional data transfer, meaning you can use
the keys of the radio or the Smartbox in order to change/enter values in the sensor. Using speech
output is not possible in this mode.
In data-mode the values are only transmitted in a fixed format in one direction. The format is
defined by the sensor type. In this mode it is possible to have speech output for the sensor
values.
2.3.1 Sensortype
The VSpeak ECU Converter for HoTT is a GAM (General Air Modul), a ESC (Electronic
Speed Controller) –or a VAR (Vario). Please select this sensor-type on your radio or Smartbox.
2.3.2 Textdisplay
Using the text-display you can see the current ECU data and you can also change parameters
of the ECU converter.

2.3.3 Data-Display/Speech
2.3.3.1 GAM - General Air Modul
"EIN" indicates that the turbine is in the "Running" status.
Since the GAM can only display temperatures up to 235°C, the temperature is divided by 10.
If you see a value of 45°C on the display, you have a "real" temperature of 450 - 459°C.
The fuel level is shown as gauge in % and as numbers in ml. To calculate the percentage of
tank volume value FUEL-Size is 100% fully set when turned on.
2.3.3.2 ESC - Electronic Speed Control
The ESC temperature display is limited to 235 ° C, so the turbine jet temperature is shown
divided by 10, or the other way around: 45 ° C in the display corresponds to 450 ... 459 °C.
The fuel consumption is displayed on the display as capacity value, ie, 2050mAh are 2050ml.
On the other hand, the percentage tank level is displayed as the current, ie, 68.0A correspond

to 68.0% tank level. The tank level is thus easy to read via the associated bar display. To
calculate the percentage of tank volume value FUEL-Size is 100% fully set when turned on.
2.3.3.3 VAR –Variometer
The HoTT Vario offers the possibility to display texts, in the example two lines with an MC20.
The bottom line shows the turbine status or error messages. If the turbine is in the "Running"
status, the lower line shows the EGT and the remaining fuel in ml.
The tank level is converted in a percentage and displayed as altitude, e.g. 68m corresponds to
68% tank level (can be used for the speech output). To calculate the percentage of tank volume
value FUEL-Size is 100% fully set when turned on.
Furthermore, the alarms according to section 2.3.4. are also effective here.
2.3.4 Parameterization The change of sides takes place
with Enter and ESC button of the
SmartBox or with the appropriate
buttons on the HoTT transmitter.
The parameter is selected with
the INC- and DEC-buttons of the
SmartBox
(or the buttons oft he Hott
transmitter) „>“.
With or the value of the
selected parameter is enabled for change
(inverted).
Witht the value can be increased,
with it can be reduced.
