  4.2.1 Save/load Live Data

  ---

  
  
  Click the Save log button to store a Live Data session.
  
  
  
  Select the parameters and number of samples to be saved from the Save log dialog.
  Choose your desired filename and directory and click the OK button.
  
  
  
  Previously saved log files can be reviewed at any time by using the Load log button.
  
  Real-time playback is available for the Live Data Graph and Vehicle Dynamics display after loading a log by pressing the play button next to the time slider.
  
  
  
  

  4.2.2 Live Data log format

  ---

  A Live Data log is saved as a CSV* file inside a ZIP container. Any ZIP compatible unpacker can be used to extract the CSV file inside, which can then be used in almost any spreadsheet and database applications.
  
  Subtitles will be saved in the commonly used .srt format, which you can then edit into your own driving videos using third party applications. Please note that logs saved in this format can not be loaded back into RSTuner.
  
  
  
  Example of a video using live data subtitles generated by RSTuner.
  
  
  
  * Starting with RSTuner 1.6.7 - If you have old Live Data log files made with previous RSTuner versions and wish to convert these to the new CSV format, simply load them in the latest RSTuner and re-save them.
  
  
  
  

  4.2.3 Live Data for engine recalibration

  ---

  The best way to log data for engine recalibration purposes, is to make a 3rd gear full throttle run, with traction control switched off.
  
  Making the full throttle data log run:
  • press tab Live Data Graph
  • press settings button and select the parameters you want to see on the screen (example: RST default profile)
  • press the Live Data button at the top of the screen to start recording the engine parameters. The Live Data Graph has an auto scale function
  • drive away, shift to 3rd gear @ 2000 rpm
  • press the throttle pedal fully until redline on your tachometer
  • find a spot to park the car safely
  After the run is done do the following;
  • press Save Log button at top of screen --> Save Live Data session
  • Click 'toggle all' button to select ALL parameters for saving to a log file
  • Click 'Save as' button to save the log file
  NOTE: Disconnecting from the car before saving the logged data erases all previous logged data. Save the logged data first !
  
  
  
  

  4.2.4 Live Data interval

  ---

  (applicable to CAN vehicles only)
  
  Our newest RSTuner hardware has become so fast that in combination with the bandwith and speed available on the CAN network it is possible to overload the ECU with Live Data requests. To prevent this a certain amount of throttling of the requests is necessary, which is what the interval setting does. A higher setting means more time between requests and thus less stress on the ECU. If you experience 'gaps' or pauses in your Live Data logging, a higher interval might be required. However, a higher interval means less accurate logging, so the ideal setting is the lowest one that does not give you problems.
  
  This setting also affects Performance Analyzer accuracy (since it uses live data requests to get engine data).
  
  
  
  

  4.3 Diagnostic trouble codes

  ---

  After a connection has been established, ECU fault codes are automatically retrieved from the ECU.
  Stored codes are highlighted in orange and present codes in red.
  
  Stored codes mean there was a problem, but it is not present anymore.
  Present codes mean there is currently a problem.
  
  
  
  The DF codes listed are the official Renault fault codes.
  
  Clear existing codes after making necessary repairs, by pressing the Erase DTC button (if you have access to multiple ECUs, select the proper target ECU first).
  
  
  
  After successful erasure of the codes, use the Refresh DTC button to refresh the current state of DTC for all available and supported ECUs.
  
  
  
  

  4.4 Performance Analyzer

  ---

  
  
  The Performance Analyzer (from hereon abbreviated to PA) allows you to measure the performance of your vehicle.
  
  (also see 4.2.4 Live Data interval if you are experiencing problems with your measurements)
  
  
  
  How it works
  
  The PA measures engine speed reported by the ECU, many times per second. Based on this, the PA calculates wheel performance from vehicle weight and acceleration rate. All that is needed is a simple full throttle in gear test of the engine on a flat road surface. Obviously it is important to use the correct vehicle weight including driver weight.
  
  How to make a PA log
  
  Using the PA is very simple. Start the PA by filling in the total vehicle weight and pressing the Activate PA mode button.
  The PA is now activated and waits for the throttle WOT trigger to start collecting performance data.
  Start driving and accelerate slowly to 3th gear, now press the accelerator pedal to the floor from low revs down. When it is time to shift to higher gear release the accelerator pedal. PA will automatically abort collecting data.
  
  PA will now display calculated wheel power -torque and -horsepower on the screen. Total drag power is also shown which is the amount of power your vehicle needs to overcome air resistance. You may save the PA log for later analysis. Or make additional logs driving in the opposite direction for wind speed correction.
  
  
  
  The following conditions will help the PA to produce the most accurate performance results.
  • Correct total vehicle weight including fluids and driver weight.
  • Correct tire size stored in ABS ECU.
  • Flat road surface.
  • No or little outside wind.
  
  
  The vehicle weight specified should be the current weight of the vehicle at the time of the test. Including number of occupants, fuel tank level, any items being carried in the car.
  Underestimating the vehicle weight will produce lower performance figures.
  Overestimating the vehicle weight will do the opposite.
  
  Aerodynamics
  
  PA takes into account aerodynamic drag when calculating engine performance. Vehicle drag co-efficient and frontal area are the parameters required to calculate power lost to aerodynamic drag. These parameters are known by RSTuner after connection to the vehicle.
  
  How does the PA compare to a chassis dynamometer?
  
  PA gives real world performance figures in power at the wheels. Not a single correction is made during calculation of the result. This is the power that the vehicle is putting down onto the road, plain & simple.
  Every chassis dynamometer is different with different cooling setups. Therefore results will vary amongst different dyno’s.
  
  NOTE: PA results are influenced by outside conditions like wind and road surface.
  
  SAFETY CONSIDERATIONS: Always perform PA testing with 2 people. The vehicle driver must have his eyes on the road at all times. PA should only be used on private roads and test tracks. Under no circumstances should performance analyzing be carried out on the public highway or in any other situation where its use may break speed limits or contravene any laws. Fastchip takes no responsibility for inappropriate use of the PA.
  
  
  
  

  4.5 Reading data from the ECU

  ---

  Before reading or writing the control unit, read 6.0 Reprogramming precautions to ensure a successful procedure.
  
  

  4.5.1 Read ECU

  ---

  
  
  RSTuner allows you to backup the ECU software. Always carry out this procedure BEFORE attempting to write the ECU with updated software.
  
  For reading or writing the contents of the ECU the engine must NOT be running.
  Before reading or writing the control unit, read 6.0 Reprogramming precautions to ensure a successful procedure.
  
  
  
  Wait patiently until RSTuner has finished and saved the ECU contents to hard disk.
  
  
  
  

  4.5.2 Read CAL

  ---

  
  
  Performs a calibration read instead of a whole readout of the ECU. Typical calibration file size is 32 kB – 64 kByte.
  Not supported by every vehicle type.
  
  
  
  

  4.6 Writing data to the ECU

  ---

  Before reading or writing the control unit, read 6.0 Reprogramming precautions to ensure a successful procedure.
  
  

  4.6.1 Write ECU

  ---

  
  
  NOTE:

  Mégane II and Clio III owners NEVER ATTEMPT A FULL WRITE OF THE ECU WITHOUT A SUITABLE BATTERY CHARGER ATTACHED.

  (See 6.0 Reprogramming precautions).
  
  Allow you to write the ECU memory content. Always make a backup of your ECU first, if not done so already.
  
  For reading or writing the contents of the ECU the engine must be stopped.
  Writing the ECU is at your own risk. Read 6.0 Reprogramming precautions and 9.0 Disclaimer before usage.
  
  Choose the correct file for your ECU. Choosing the right file is your own responsibility. Programming the wrong file may result in ECU failure or engine damage. Also read section 5.0 Which calibration file to use.
  
  A write ECU procedure may take up anywhere between 10 ~ 30 minutes to complete, take the necessary precautions to ensure the procedure will complete successfully.
  
  NOTE: After each reprogramming ECU learning values such as, idle offset, fuel trim etc. are erased and set to their default values. Allow up to 10 drive cycles for the ECU to complete learning these values again. This learning behavior can cause unstable idle rpm after reprogramming.
  
  
  
  

  4.6.2 Write CAL

  ---

  
  
  Performs a calibration (partial) write of the ECU. Typical calibration file size is 32 kB to 64 kB.
  
  Calibration writes allow for faster ECU reprogramming, but only writes a small portion of the ECU’s memory. Therefore before writing, always verify the software version number equals the file software version number. The calibration numbers are of less importance, but the software version numbers always have to be equal to each other.
  
  
  

  Verify software version dialog

  
  
  Also see 5.0 Which calibration file to use.
  
  
  
  
  
  
  
  

  5.0 Which calibration file to use

  ---

  NOTE: Programming the wrong software version can inflict permanent damage to the ECU and its sub-systems.
  
  On the Fastchip.nl ECU calibration download page all files are named xxxx_xxxx. The first 4 digits mark the software version, which tells the ECU what to do. The second 4 digits mark the calibration version, which tells the ECU how to do things. So if you see a file named 6400_2A07.rst it tells you, its software version 6400 and calibration version 2A07.
  
  Now, how to determine the correct file download for your car?
  
  Let's assume you have a 172 Clio II. Connect to the car with RSTuner and look at the status bar after connection is established. Here you can see the car's VIN: VF1 CB15 0629638376.
  
  Go to the proper download directory on the ECU calibration download page, according to the car's type designation. In this particular case CB15.
  
  Now look which software version the ECU is running. The first 4 digits, remember? You can find this on the ECU information tab. In this case 6400.
  
  
  
  In case you want to carry out a total ECU reprogramming (.rst file Write ECU) you need to use a .rst file that begins with software version 6xxx_xxxx. Programming anything else could do harm, see above statement.
  
  Examples total ECU reprogramming (.rst file Write ECU)
  • 6100_2AB0 --> 6500_5404 OK
  • 6400_2A07 --> 6500_5404 OK
  • 6100_2AB0 --> 7300_5B10 NOT OK CAUTION
  • 8000_7802 --> 8100_7803 OK
  
  
  In case you only want to perform a partial ECU reprogramming (.cal file Write CAL) you need to have a .cal file that begins with the same software version number, in this case 6400_xxxx.
  
  Examples partial ECU reprogramming (.cal file Write CAL)
  • 6400_2A07 --> 6400_5400 OK
  • 8100_7802 --> 8100_7803 OK
  • 9100_4008 --> 9100_4005 OK
  • 6100_2AB0 --> 6500_5404 NOT OK CAUTION
  
  
  
  
  
  
  

  6.0 Reprogramming precautions

  ---

  --------------------------------------------------------------------------------------------------------------------
  Reprogramming the ECU is for your own risk at all times !
  --------------------------------------------------------------------------------------------------------------------
  

  
  Re-writing the ECU can take 2 - 50 minutes, depending on the ECU in use and size of upload file.
  
  Whenever performing an ECU reprogramming, make sure you program the correct software version compatible with the software that already resides on the ECU. ( See also section 5.0 Which calibration file to use )
  RSTuner software has a unique feature in the form of a "Verify software version dialog" which gives the user the chance to verify the software version he/she has chosen against the actual version that resides on the ECU, before each reprogramming session.
  Programming the wrong software version can inflict permanent damage to the ECU and its sub-systems.
  
  A 100% battery condition + 10A battery charger are crucial when performing a full ECU rewrite.

  6.1 Clio III battery discharge

  ---

  During reprogramming the engine cooling fans come on. This will quickly discharge the battery which might lead to a programming failure. Therefore it is highly recommended that you remove the cooling fan relay located in the engine bay next to the battery before each reprogramming.
  
  
  
  Remove lid to gain access to the cooling fan relay (7) ,towards the front of the car. Unplug it before every reprogramming sequence. Do not forget to install the relay again after reprogramming is done.
  
  NOTE: Unplugging this relay will only disable the high speed cooling fan.
  
  A battery low charge signal may be heard during reprogramming, but do not interrupt the programming sequence. Always let the programming continue until it is finished.

  ---

  Our RSTuner Premium version offers a 'Flight Data Recorder' which can record many hours of engine live data on its internal storage without the use of a laptop, simply by pressing the control button. Up to 64 sessions and approximately 100 hours* can be stored before the user has to transfer them to their PC for review purposes. Furthermore, RSTuner Premium allows you to set any available engine parameter as a trigger for the output channel.
  
  * Total recording time varies on the vehicle you are connected to and interval setting (see 4.2.4 Live Data interval).
  
  
  
  
  
  

  7.1 Stand-alone data logging

  ---

  Please note: before being able to use the stand-alone features of your RSTuner Premium, you must first have:
  • connected to your vehicle with RSTuner software at least once (this stores the car's VIN internally, which will be referenced by the data recorder.)
  • accessed the RSTuner Premium Control Panel at least once (this writes the proper configuration for your vehicle to the internal memory)
  Now your RSTuner Premium is ready for stand-alone functionality.
  
  
  
  Please note: Whilst pressing the control button and it doesn't respond, release and wait atleast 1 second before trying again. (anti- bounce delay)
  
  Start manual gauge data output (gauge module support)
  • Make sure engine is running
  • Start gauge data output by pressing the control button for more than 1 second until the GREEN indicator LED comes ON (engine must be running)
  The VCI will try to establish communication with the engine ECU and start with gauge data output.
  
  
  
  Start recording
  • Make sure engine is running
  • Start data recording by pressing the control button for more than 3 seconds until the ORANGE indicator LED comes ON (engine must be running)
  The VCI will try to establish communication with the engine ECU and start with data recording.
  
  
  
  Stop recording
  • Stop data recording by pressing the control button for more than 1 second until the indicator LED goes OFF.
  Important: Stopping the engine or powering down the interface while it is recording will cause a loss of the last recorded data session. Always stop recording first.
  
  
  
  Erase recording
  
  When not logging, press the control button for more than 10 seconds until the RED indicator LED comes ON, to erase ALL logs.
  Important: This will erase ALL logs currently stored in the interface. Your config will not be erased.
  
  
  
  Indicator LED
  • RED Transmitting data to vehicle
  • GREEN Receiving data from vehicle
  • ORANGE When all 64 data sessions are used, the orange LED comes ON when data recording is started. This means that recording will be combined with the last session (no new session will be created) .

  ---

  
  
  Interval (applicable to CAN vehicles only)
  
  See 4.2.4 Live Data interval.
  
  
  
  Include AD / wideband requests (connector inputs)
  
  Tick the box, if you want to process the connector inputs (4) as well. If not, it's best to leave it off since it slightly improves Live Data logging frequency.
  
  
  
  

  7.2.3 I/O Trigger

  ---

  
  
  RSTuner Premium allows you to set any available Live Data parameter as a trigger for the output channel.
  • Select the parameter you wish to use as trigger, it will show you the theoretical range of that parameter (this may go beyond the practical range)
  • Set 'Trigger ON' to the value above or below which you want the output to turn on
  • Set 'Trigger OFF' to the value above or below which you want the output to turn off
  • Save configuration
  The I/O trigger can be reset & disabled by using the 'Reset / disable trigger' button.
  
  For information about connecting hardware to the I/O see 8.0 Input / Output (IO).

  8.2.1 Sample relay circuit

  ---

  The following circuit uses a Bosch Automotive Relay, Part Number 0-332-204-150. When and how the relay turns on and off by tracking any engine parameter or A/D channel value is configured in the RSTuner Premium Control Panel. The output can be used as a status indicator or external high current device control. NEVER use the interface to control relays where safety is an issue or vehicle damage may occur. Do not forget to add the driver protection fuse.
  
  
  
  
  
  

  8.2.2 Sample light circuit

  ---

  The following circuit uses a 12V warning LED with acoustic warning signal.
  When the light / buzzer turns ON and OFF by tracking an engine or A/D channel parameter, is configured in the RSTuner Premium Control Panel. You can use any type of light/color you want, as long as it does not draw more than 100 milliamps when lit. If it does you will need to add a driver relay to isolate the interface unit from the larger current draw (see 8.2.1 Sample relay circuit,).
  
  
  
  
  
  

  8.2.3 Sample analog circuit

  ---

  With our Pro / Premium interface, you can integrate 0-5v analog signals from various sensors such as EGT, wideband and others right into our Live Data logger. You will have real time data from those sensors right next to your engine Live Data such as TPS, RPM, KMH, etc.
  
  The following circuit shows the connection between the 0- 5v analog output from an aftermarket wideband controller or EGT sensor (exhaust gas temperature) using the supplied pigtail connector.
  Refer to the manufacturer’s documentation on how to connect and configure their device.
  The analog signal may be connected to any of the four analog inputs.
  RSTuner software has predefined inputs for Techedge and Innovate wideband controllers.
  
  Techedge Wide Band O2 - TE 2A0: result = volts / .5 + 9
  Innovate Wide Band O2 - LC1: result = volts / 0.3324 + 7.35
  Raw voltage: result = volts / 1 + 0
