PWC SSL Handbook
1. INTRODUCTION
This document outlines the implementation of the new Series Spec Logger as it pertains to the 2016
Pirelli World Challenge Series. All GT classes will require a MoTeC logger. This logger must be setup
via the guidelines set forth by PWC as outlined in this document. The Series Spec Logger will be open
for teams to use and configure themselves. Display settings, additional channels and sensors and
logging are all open for the teams to use as they see fit. Most other series around the world have very
controlled loggers, adding cost with no added value to the teams. We hope this program continues to
be open and encourage teams to use the data for driver coaching, system and engine checks and
doing their own compliance checking. This handbook will change and be updated as needed
throughout the year.
Please refer to the Pirelli World Challenge Technical Regulations for a complete list of rules.
2. WHERE TO PURCHASE
Teams are allowed to purchase their MoTeC logger from any North American MoTeC dealer. It is
highly recommended to purchase from a dealer whom you wish to be supported by. Your MoTeC
dealer will be your first contact for all support needs. Installation, setup and training are all things you
should consider in detail when deciding who to purchase from.
All MoTeC loggers will require a setup check before competing in the PWC series. This will help
ensure proper configuration and compliance within the guidelines set forth by PWC and listed in this
document. That check will be done by Christopher Brown of CB-Racing. He will be the main MoTeC
support dealer for the PWC series. If you have any questions regarding the PWC SSL please contact
him through email at: [email protected]
3. ALLOWED MOTEC LOGGER MODELS
Any L1xx or C1xx will be eligible for 2016 and beyond. Model numbers include: L120, L180, C125,
C185, C127 or C187. The last digit is the display screen size in inches. The CDL3, SDL3, ADL3 & ACL
are also eligible for 2016, and may or may not be eligible after 2016 due to software or hardware
limitations of future additions to the PWC SSL requirements. The older MoTeC loggers such as the
ADL, SDL and ADL2 are not eligible.
Essentially the newest range of MoTeC loggers will have all of the features required for PWC in the
foreseeable future. The older MoTeC dashes can not be upgraded with regards to certain functionality.
Hence some are eligibility for 2016 but not guaranteed beyond 2016.

Option List for Loggers:
These options may be enabled at any time, and never expire on the logger purchased for.
I/O Options: Activates additional sensor input pins on the back of the dash. On the 12x series
loggers this option is required for measuring boost pressure, but may not be required for normally
aspirated cars where all the required data is being streamed through the CAN bus. On the 18x series
loggers a number of inputs are already included. See table above for Analog Sensor Inputs.
Pro Logging: All data files created on MoTeC loggers can be opened in i2 Standard analysis
software. This software is free to download from the MoTeC web site. The Pro Logging option enables
data files created by the logger to be opened using i2 Pro analysis
software. The Pro software is also free to download and adds advanced
functions like shock histograms, advanced math equations, unlimited
graphs and worksheets, setup sheets, etc. i2 Pro only opens pro files, i2
Standard will open both Pro and Standard data files.
Memory / USB: This option doubles the onboard logging memory
and on newer dashes it also enables the external USB logging. Beginning
in 2016, all MoTeC L1xx and C1xx loggers will have the ability to utilize a
USB memory stick. Older models won't have USB but will have the
additional memory increased when buying this option.

T2 telemetry $ 2510 $ 2925 activates the T2 telemetry data stream *radios extra
Optional SLM - SHIFT LIGHT MODULE
The MoTeC SLM features bright multi-color LEDs which are ideally suited for a multitude of functions
such as shift lights, warning lights, yellow flag lights or brake lockup lights. This is the perfect way to
increase the functionality of your MoTeC logger to help the driver. It is easily adapted to any MoTeC
logger with or without a display. For many installations the steering wheel blocks the built in light array.
An external light module is easily mounted further up on top of the dashboard where it can be in the
peripheral view of the driver. Cost is $585.

5. Required GPS
The PWC SSL will require its own GPS. You may choose between
two models of GPS, the MoTeC L10 or RaceGrade BLv2. The L10
model is lower cost but suffers from increased variation in positional
data, essentially making drive line analysis difficult due to drift. The
RaceGrade model has much more accurate positional data useable
for drive line analysis but at an increase in
price. Only the positional data is different,
the speed data of either one will be similar
because speed is calculated from the
Doppler Effect rather than triangulation for
positional data. Both update at 10 Hz,
though a 20 Hz output is optional on the
RaceGrade BLv2.
The GPS antenna must be fitted on
top of the roof, and with a minimum
distance of 6" from any other antenna.
6. WIRING HARNESS
For teams utilizing the PWC SSL as their main data logger, any harness will be allowed. For teams
using the PWC SSL as a series logger only, a simple standard adapter harness is available and can be
specially configured for lengths upon request. The required connections for all cars are:
1. Battery Positive & Ground
2. GPS
3. CAN / OBDii
4. Boost Sensor where required
5. Download / PC connection
6. Yellow Flag integration is recommended but not required for 2016
CAN Connection
For cars which come already with the GT3 Spec Logger
connection, many of the required channels can be grabbed off
that CAN stream. For other cars, a direct connection to the
factory CAN bus with decoding information is required. If the
factory CAN is not available, OBDii may be used. Please refer
to the required channel list to make sure you can comply with
the regulations. CAN channels must come directly from the
originating source, and all vehicle CAN data transmission is
subject to inspection at any time.
Requirement for Boosted Cars
Boosted cars must have an external visually traceable wire lead from the main connector of the
dash straight through to the sensor. It can not be bundled with any other wires and shall contain only 3
wires; 0v, signal & 5v. Connectors in the path from the logger to the sensor, such as a firewall
connector, must also not contain any other wires. Connections, wiring pinouts and installation is subject
to inspection at any time.

9. DATA GATHERING
Data will be downloaded directly off all cars passing through tech. Logging memory will not be erased
during this download. For cars not going through tech, a USB memory stick must be turned in within 30
minutes of the conclusion of every session with the corresponding data files. PWC will provide one USB
memory stick to all teams.
10. Logger Serial #
All MoTeC logger serial numbers must be on file with PWC. This includes any spare units.
11. CONFIGURATION FILES
All logger device configuration files must remain open to PWC. No passwords are allowed without
disclosing them to PWC. Data files without the device config will be deemed non-compliant. The series
will keep a master copy of all configuration files to be used in the event of communication and sensor
verification, (i.e. CAN setup and boost sensor input identification).
12. MOTEC DATA FILE DETAILS
To keep data files standardized, some detail information guidelines are required. An example image of
the details editor is shown below.

14. YELLOW FLAG LIGHT SETUP
Optional Integration
The existing yellow flag system utilized in the Pirelli World
Challenge series already has the capability to integrate and
communicate directly with almost any data logger or display
including the entire range of MoTeC loggers. The MSE box has
an external digital output which signals when the yellow flag light
system activates. Similar to the output which drives their yellow
light, this digital output wire is ran directly into an input pin in the
logger. A yellow flag channel can then be logged within the data
allowing for easy determination of when the in-car yellow flag light
system is active. It can also be used to notify the driver via an
Alarm on the display AND activate the driver's shift lights by flashing them yellow. The driver's shift
lights are often in better than the current small remote mounted light simply because they are often
placed more in line with the driver's view and the driver is constantly watching them.
All new MSE boxes and wiring harnesses will have an external trigger wire available. Older
existing systems will need to be upgraded by MSE. Please contact Bruce Natvig at 765-316-3399 or at
[e-mail]
Below is an example of setting up the yellow flag wire onto the SPD3 input pin with a calibration
setting of low volts = active. This channel may then be used to create an alarm and under the SLM
setup to activate lights. It should also be logged at 10 Hz.

15. ANALYSIS SOFTWARE INFORMATION
MoTeC’s i2 data analysis software has been developed over a number of years with
valuable input from professional race teams worldwide. It delivers an extensive
package of powerful analysis tools that allows for customization by the teams.
The i2 software is available in two versions, i2 Standard and i2 Pro. Both may
be freely downloaded from the MoTeC website. The i2 Pro software features additional
functionality required for high end analysis such as custom math equations, shock analysis and
unlimited graphs. It is not required for PWC compliance checking nor basic driver or engine related
needs. i2 Standard will include all required PWC compliance equations so you can check your own
legality without requiring the pro option. i2 Pro can be purchased as an option code enabled on
individual MoTeC loggers. Once enabled i2 Pro remains active for the life of the logger, and all data
files can be opened with the i2 Pro software on any number of computers without limitation. No dongle
required. Both types of data files can be opened in i2 Standard, but only data files from pro enabled
loggers may be opened in i2 Pro.
Compliance checking is done with either version, often taking the form of a channel report
shown below. An i2 workspace will be made available with a standard set of graphs and reports as a
starting point for any team. The workspace will also contain all the tracks with sections all preset.
