6. RADIO / SPEED-CONTROL SET-UP
In setup mode the NOSRAM MATRIX EVOLUTION ISTC stores every step when you press the SET button.
All the settings will be stored in the speed-controls memory even if the speed-control will be disconnected
from the battery.
TRANSMITTER SETTINGS
Setup the following basic functions on your transmitter (if available):
Throttle travel High ATV, EPA High ATV, EPA
Brake travel Low ATV, EPA, ATL
Throttle exponential Throttle exponential EXP, EXPO
Neutral trim SUB Trim
Servo reverse Throttle reverse
If your transmitter doesn't offer any of above functions, it's already in „basic setup" mode.
• Ensure that the speed-control is not connected to the drive battery and is switched off.
• Remove motor pinion or ensure that the wheels of the model are free to rotate.
• Switch the transmitter on and set the transmitter throttle stick to neutral.
• Connect the speed-control to the battery, and switch the unit on.
• Hold the SET button pressed for at least 3sec using the supplied plastic screwdriver.
 You entered setup mode and the SET LED flashes blue (it will flash until the setup is completed).
• Leave transmitter in neutral position and press the SET button once.
 Neutral setting is stored , MODE LED flashes yellow and the motor beeps.
• Hold full throttle on transmitter and press the SET button once.
 Full-throttle setting is stored, MODE LED flashes red.
• Hold full brake on transmitter and press the SET button once.
 Brake setting is stored, LED's glow red (MODE) and blue (SET).
• This completes the setup procedure and your NOSRAM MATRIX EVOLUTION ISTC is ready to use.
• If you make a mistake during the setup procedure, don't worry: Disconnect the battery for about 10sec
and start again from the first step.
• At the end of each run switch of the car, and then switch off the transmitter.
• At the start of each run switch on the transmitter first, then switch on the car.
• For storage of the car, disconnect the drive battery at any time!
CHECKING THE FUNCTIONS:
Check the LED's when moving your throttle stick and you will see if everything is setup correctly.

8. SPECIAL FEATURES
Smart-Temp-Readout-System: As a world-exclusive the NOSRAM MATRIX EVOLUTION ISTC allows
you to read-out the maximum internal temperature that the speedo reached. To save it to the memory you
have to briefly apply brakes after the run before you turn the switch off. You can convienently read-out the
temperature back in the pits since it remains stored until you turn it on the next time regularly (which will
reset the memory). This new feature allows you to accurately check if all is running well or if you're close to
shutdown already.
How to read-out the temperature:
 Switch at „OFF" position.
 Keep MODE button pressed while you turn switch to „ON" (then release button)
 SET LED will start to flash blue (MODE LED is off), now count the number of flashes.
• Thermal shutdown of the speedo would occur at 5 flashes.
• The higher the number of flashes, the cooler the speedo ran (e.g. the better it is!).
• Every flash over 5 equals to ~8°C lower internal temp. (e.g. 10 flashes is 40°C below shutdown)
Launch Control: Well known and famous from our brushed speedos! Now also available for brushless, the
launch control allows „rocket like" starts. After activation it gives you more power one time for the start (this
feature is only recommended to be used with touring cars on high traction surfaces!).
How to activate launch control:
 Hold trigger of transmitter at full brake for 5sec before start. Ready and active!!!
SmartCell System: Ready for the next battery technology – LiPo batteries! NOSRAM's exclusive and
smart SmartCell System ensures that LiPo batteries can be used safely without accidentially deep-discharging
of the cells. The motor function will be shut-off and the SET LED will flash if the system recognises very low
battery voltage.
Tip: We recommend using value 2 for 4-6 cells NiMH racing purposes, which disengages the LiPo protection.
XPS.2 Brushless - Power Profiles: An all new brushless technology which results in more power
and better driveability. Depending on the status of the car (start, acceleration and full speed) the software
calculates the perfect motor management. Higher value means more overall power and aggressive response.
Caution: Do not advance mechanical timing on the motor. Leave the motor timing on minimum timing, which
equals to 2mm on the sticker.
PMS.2 Brushed - Power Profiles PMS.2 Brushed - Power Profiles PMS.2 Brushed : The known and world's winning PMS.2 Brushed power programs
have been implemented into the NOSRAM MATRIX EVOLUTION ISTC aswell. Higher value means more overall
power and aggressive response.
Automatic Brushless / Brushed Adaption: The NOSRAM exclusive Automatic Brushless/
Brushed Adaptation detects the connected motor type during turn-on/initialisation and adjusts the correct
brushless or brushed operation automatically. No adjustments required by yourself, apart from the correct
connection of each motor type (don't forget the hall-sensor-wire for brushless!).
Caution: Keep in mind, when swopping between brushless and brushed motors, that the chosen mode values
will be identical!
Changing Mode settings without the transmitter: At race events you usually do not have
access to your transmitter, but never mind since you can simply disconnect the receiver lead from the receiver
and change the MODE settings as described in section 7 „Mode Programming".

7. MODE PROGRAMMING
All modes are available for brushless and brushed motors (speedo adapts automatically). The NOSRAM
MATRIX EVOLUTION ISTC features 4 modes which enable you to adjust it to YOUR special requirements. The
factory settings are shown in grey colour.
• How to get into „programming the modes"
• How to check the stored values
• How to change the value
• How to get to the next Mode
• How to leave the programming mode
• Table of settings, values and modes: see below (grey-shaded values show „works default settings").

• Touring Car: Brushed: 3-5
• 1/12: Brushed: 2-3
• 19/27T motors: Brushed: 5-6
MODE.3 (Initial Brake): Allows you to set a certain level of „hand-brake-effect".
MODE LED Value 0 Value 1 Value 2

Team Tips: A good starting point for the brake setting on your radio is 80% (bonded) and 70% (sintered)
for all classes. Make sure you do the radio-setup with all settings on the radio on 100%.
MODE.4 (Automatic Brake MODE.4 (Automatic Brake MODE.4 ( ): Allows you to set a slight braking action in neutral range.
MODE LED Value 0 Value 1 Value 2
Yellow/Red (same Yellow/Red (same Yellow No Automatic Going from lowest to highest automatic brake setting
time) Brake
Team tips: For brushless motors you achieve the same natural slowdown as a brushed motor with no autob-
rake when you set value 2/3 (for bonded magnets) or 0/1 (for sintered magnets).
Works-Default-Settings: All NOSRAM speed-controls come factory-adjusted (defaults are grey-
shaded above). If you loose track of the modes, you can restore the works default settings. With the transmit-
ter switched on, hold the SET button pressed while you switch on the speed-control. This simple action returns
the unit to the NOSRAM works default settings.
Power Capacitor: Never disconnect the power-capacitor! It offers increased punch and additional pro-
tection.
FreezeDrive Design: NOSRAM's secret FreezeDrive Design results in lower speedo temperature under
all racing conditions and for both brushless + brushed. Sorry, no further details to be disclosed. Simply a step
ahead of the competition!
Forward/Brake: Uncompromising and outstanding performance for top level competition was the target!
Therefore the NOSRAM engineering team developed a pure forward/brake competition speed-control without
reverse function.
Sensored Brushless Technology: Enhanced Digital allows the perfect knowledge of the brushless
motor's magnet position. This results in perfect motor control at high and low RPM's, as well as perfect brake
control.
Multi-Protection System, 3-way protection: The perfect protection against short-circuits
(motor), overload and overheating. If your speed-control faces overload, the motor function will be shut-off for
protection and the SET LED will flash, although the steering function is maintained. Let the speed-control cool
down for a few minutes. If you experience frequent shutdowns, check for the following:
• Correct gear ratio (refer to motor manual for gearing recommendations)
• XPS.2 setting too high (higher value will heat up motor a • XPS.2 setting too high (higher ue will heat up motor and speed
• Motor is too strong or motor is damaged. • Motor is too strong or motor is damaged.
 Press MODE button for 3 or more seconds.
 Count the number of flashes of the blue SET-LED
(1x = value 1, 2x = value 2, etc.).
 Press SET button to increase value by one step.
