1. PREFACE
This manual contains instructions about PowerTRONIC; its use, care, maintenance and
technical data.
Please read this Manual carefully. Operation in accordance with these instructions is a
prerequisite for proper use of the system.
We hope that the use of our product transcends into an experience.
2. SETTING UP THE R-TUNE PowerTRONIC TUNING SOFTWARE
System Requirements
Minimum Recommended system configuration
OPERATING SYSTEM
WINDOWS XP/VISTA/7/8/10
RAM
512 MB (minimum)
USB Type A port
2. B. Setup Walkthrough
-
Open/Extract (using winzip/winrar/7zip etc) the setup.zip file and run setup.exe.
-
Follow the installation wizard to complete the installation process.
-
The setup automatically places a shortcut to R-TUNE PowerTRONIC2.0 on your desktop.

2. C. Connecting to device
a. PowerTRONIC comes with the SiLabs CP2104 chipset for USB communication. You
will need to download the drivers for your computer from here. Alternatively, you
can search for ‘CP2104 VCP’ and download and install appropriate drivers.
b. Once installation is complete, plug in PowerTRONIC to the computer using the
shielded USB 2.0 cable provided, wait till Windows notification alerts you of a new
device and finishes installation (first time use), then click refresh icon next to
connect button, click on drop down list and choose the appropriate port number
and click connect.
c. If you are not aware of the port number, you can go the device manager -> ports
and look for CP2104 com port number, this is the port number allocated by
windows for the device. Select this number from the drop down list on R-Tune PB
and click connect. On successful connection you will have ‘Connected’ status and
a free running status bar on the bottom right indicating data exchange in progress.
d. PowerTRONIC is a USB powered device, so it does not need to be connected to a
vehicle or specifically turned on to establish communication with the computer.
3. QUICK START –
 Connect the injector and ignition coil. Each injector and ignition will have two
connections to PowerTRONIC – one side going to the actuator (injector or ignition
coil) and the other side towards stock ECU (Refer installation guide for your vehicle)

Connect the ground terminal to a battery/chassis ground. Ensure this connection is
free of paint, and other insulating materials. It is important the ground is good

Start the bike. If the bike refuses to start, refer Troubleshooting


Setting load input type, and min-max calibration of the same, you can choose
injection pulse width or Throttle Position
 Start mapping if needed, or use the base maps provided.

4. C. Fuel Mapping
This screen shows the Fuel Tab which is a Fuel Map
This table is used to control
fuel delivery. You can increase
or decrease delivered fuel
quantity. The fuel tables are
arranged RPM vs Load, min
load at the bottom and max
load at the top, min RPM on the
left and max RPM on the right.
To make any changes on the map you
can either individually type in the
values on each cell or select multiple
cells and right click which will give
you options to increase or decrease
by percent or value or set the exact
value .You can copy values from any
cell and paste it in any other cell
The default values are set to 0
(Stock/Original calibration). As
long as the values are at ‘0’ the
fuel injection quantity is just
like the original ECU i.e. no fuel
quantity modulation. Any value
more than 0 increases fuel, and
less than 0 decreases fuel,
controlled as a percentage of
original quantity. The nonnegative difference between
the table value and 0 is the
difference in percentage
changes
Note: Value Range -> -25 to +25

4. D. Ignition Mapping
This shows the Ignition Tab
This table is used to control the ignition timing of the engine. You can increase or decrease
ignition timing of the engine.
The ignition tables are arranged RPM vs
Load, min load at the bottom and max
load at the top, min RPM on the left and
max RPM on the right.
The default values are set to 0(Stock
calibration). As long as the values are at
‘0’ ignition timing is just like the original
ECU i.e. no ignition timing modulation.
To make any changes on the map you
can either individually type in the
values on each cell or select multiple
cells and right click will give you
options to increase or decrease by
percent or value or set the exact value
Any value more than 0 advances ignition
timing and less than 0 retards ignition
timing. The non-negative difference
between the table value and 0 is the
difference in ignition timing (in degrees)

.You can copy values from any cell
and paste it on any different cell.


Note: The rev extending feature is available on engines where the rev limiter is activated
by a fuel cut only, where engine synchronization is derived from ignition signals.
When the revcut eliminate mode is active, engine rev cut can be controlled by ‘Limiter at
RPM’ field in
Conditions to enter revcut elimination mode, in the defined order1. Load has to be above Load index
2. RPM has to be higher than RPM index
16
Example – For KTM duke the parameters ‘Injector override above RPM index’ =10 and
‘Injector override above load index’ =8, means once the load is above load index 8, AND
THEN when the RPM index is above index 10 (9000RPM), then the revcut eliminate
mode is activated.
Note: These settings are best left to advanced users with the proper equipment to determine the proper
adjustment required.

4. F. Calibration
8.1
The RPM index on the fuel and ignition tab
can be calibrated using the table RPM Index, there are
a total of 20 RPM columns on the fuel and ignition
tables that can be split accordingly
18
4. G. Traction Sensitivity
Allowable values
from 0 - 250
PowerTRONIC comes with two user selectable types of traction sensing1. TRACTION BY RPM/TIME – By deriving change of RPM at every combustion cycle which
is normalized to 1 sec and checked against the traction sensitivity table.
TRACTION BY RPM - By sensing RPM increase at every combustion cycle as a percentage
change over RPM at pervious combustion cycle.
19
4. H. Traction Attack
8Allowable
values from 0 - 50
20
Traction by RPM/Sec
This mode normalizes the rate of acceleration to increment over one second,
Traction by RPM
Traction looks at RPM increment as a percent over previous RPM
21
4. I. Setting Traction control
 Select the type of traction sensing
 Monitor the traction data in the ‘TrcRPM Status’, this is the instantaneous data the
ECU is capturing in real time, a value higher than this would activate the traction
sense and control, the traction data is converted to a unit (TrcRPM Status) that
makes it easier to use, it’s a value between 0 to 250
 Calibrate the table accordingly, based on RPM vs Load
 Test effectiveness of the sensitivity calibration by setting the entire traction attack
table to a value above 25 (ignition cut), this would mean anytime the traction module
senses a slip, the ignition will be cut, which is easier to perceive than an ignition
retard
 Test vehicle with multiple throttle positions and RPM to check if the ignition cut is
coming in when required, readjust accordingly. Then, if needed, adjust the traction
attack table to retard timing by a value 1 to 25 degrees to attain seamless reduction
of power.
The ignition retard for traction is recommended only for experienced/professional
users/tuners.
