Mobile technology and cloud data. Standard data acquisition systems utilize an on board data recorder, be it a data recorder and separate digital dash, or a data recorder dash. Information is saved and downloaded via either a removable memory card or download cable, to a PC. This method is dated, limiting and time consuming, requiring manually moving data files between multiple PC’s for viewing, using 1990’s era windows based software for programming and analysis and more importantly, not taking advantage of the mobility aspect of modern day mobile devices and cloud technology.
The CL1 Junior Dragster kit utilizes a vehicle mount mobile phone, running Racepak’s propriety D3 app and a vehicle mounted CL1 data box, to transmit sensor data via Bluetooth, from the CL1 to the mobile phone, for instrumentation, data recording and automatic uploading of data to an optional cloud account, for remote data review, on an internet connected device, anytime, anywhere in the world.
At the very basic level, a CL1 data box is mounted on the vehicle and connected to external sensors (temperature, pressure, rpm, etc.). A mobile phone, running the D3 App, is installed in the vehicle. The mobile phone then receives sensor data from the CL1, via Bluetooth, displays pit and engine information, uploads data via the cellular service of the phone to an optional cloud account and can also function as a data analysis program.
Very simple. Modern cell phones are more rugged, have far superior displays, processing power and wireless capabilities than data logging or display devices currently on the market. They are designed for constant abuse by the consumer, have incredible technical capabilities and the costs to duplicate their properties for data acquisition purposes would be astronomical.
NO. The CL1 data box contains an onboard 20 Hz GPS system, along with an external GPS antenna, providing highly accurate data for the D3 app.
The D3 app combines instrumentation, data recording, data analysis and device programming into a single location, on the vehicle mounted mobile phone.
The CL1 is merely a collection point for all external and internal sensor data, which is then wirelessly transmitted via Bluetooth, to the vehicle mounted phone running the D3 App.
8 external sensor inputs. There are four external sensor connectors on the CL1, each user programmed as an analog and RPM input.
Racepak provides an optional analog/rpm splitter, enabling the input of one rpm, one analog sensor per input
User defined from 1Hz to a maximum of 50Hz, per data channel
The CL1 data box, GPS antenna, three rubber mounting feet, four AA rechargeable batteries, USB charging cable and adapter, Engine/RPM harness, inductive rpm wire and mobile phone mount.
Four rechargeable, Ni-Mh, AA batteries.
What about battery life, as I don’t want to charge the box after every run.
No need! The CL1 has an advanced energy management plan, which keeps the box in sleep mode until an Engine RPM signal is detected. After a short period of inactivity, the box will return to sleep. A typical junior dragster day will use less than 20% of battery life
The D3 app also contains a sleep setting, allowing the phone to sleep until the CL1 data box awakens (from the tach signal) which then awakens the D3 app and phone. This function is optimized for Android devices, while IOS devices are not optimized for an external wake up signal. Instead, the D3 app can just be quickly tapped, bringing the app from sleep.
Racepak offers a complete line of RPM, pressure, travel, temperature and air fuel sensors.
Yes. If you know the calibration values for your RPM or analog (0-5V) sensors, Racepak offers an unterminated sensor cable (CL1 mating connector installed, no connector on the opposite end) which the user can install the mating connector for their sensors and connect to the CL1.
From the Settings icon on the homepage of the D3 app. remember the phone functions as the data recorder, so no need to “send” programming changes to the CL1 data box.
No. The processing properties of the D3 app and mobile phone provides highly accurate lateral and accel g data.
Low energy Bluetooth (BTLE) as it has proven to be highly robust and dependable in a variety of conditions. Remember, the onboard mobile phone is only receiving data from the nearby mounted CL1 data box, so there is no need for long range Bluetooth capabilities.
Yes. Consider the demands placed on a consumer electronic device, which typically lives in our pockets and is subject to constant abuse. Water, heat, cold, sand, dirt. Constantly taken in and out, turned off and on. Subject to continual drops, slips, and g forces and they typically continue to work

Yes. Since the phone functions as the data recorder, all data is stored locally on the phone. If the phone has Wi-Fi capabilities, as soon as the phone can access a Wi-Fi network, data is automatically uploaded to the customers optional cloud account.
It varies by the number of users. The account holder plus two remote user accounts is $9.99 month / $100 year.
In order to associate your CL1 with you, your team and remote users, the CL1 utilizes a unique serial number that must be registered before first use. This not only links your CL1 to your account, but to the vehicle mounted mobile phone, while also securing your account.

We have not found any issues with connectivity, at this time.
Racepak’s cloud service can upload and live stream data and has been tested with thousands of users, with no issues. Our software team has extensive experience in both the gaming and cloud industry, providing the most rugged, reliable and secure motorsports cloud data service, in the industry.
Racepak’s dedicated servers are located in the United States and hosted by one of the top ten cloud service providers, in the industry. This ensures reliable, 24-7 service with redundant backup and security measures for all your data.
While no technology is 100% fool proof, the hosting company selected by Racepak is ranked within the top 10 for cloud providers, servicing a number of Fortune 500 companies. Your data is in good hands.
Yes. Depending upon the optional cloud program chosen during the CL1 registration process, anywhere from 1 to 100 or more can view your data.
Only authorized remote viewers, with a unique passcode, can access your data.
Racepak has pre-loaded more than 2000 worldwide track maps into our map data base, providing simple and automatic overlay.
When the vehicle exceeds 11 mph / 5 ms and Engine RPM is detected, data transmission is initiated.
The short answer. Yes. The key area is display brightness, or Nits. A list of technical specifications can be found on this website.
Yes. As long as it has working Wi-Fi. We recommend any of the Samsung or Apple products.
Yes, remember the D3 app provides the same analysis functions regardless of the device on which it is installed.
Technically, yes. The challenge is size and mounting. If the table has active Bluetooth, you could pair with the vehicle mounted CL1 data box. You would not have data cloud upload, unless the tablet has cellular service. However, once connected to Wi-Fi (such as in the pit area) it will automatically upload data from the just completed outing.
If a cloud account is active, the data remains saved on the cloud server. If no cloud account is active, then all locally saved data on the mobile phone, is lost.
As the D3 app is designed for use with mobile devices, all the intuitive actions such as touch, swipe and pinch can be utilized. In addition, the superior resolution capabilities of modern tablets exceeds the capabilities of most laptops and PC’s proving greater detail.
Automatic. When the vehicle mounted phone and CL1 data box powers up, the CL1 data box is “checked” by the D3 app for the latest software version. If a newer version is detected, it is automatically installed and the viewer notified of the current installation action.
How do zero a run
No need. The D3 app automatically zeros the run, displaying data 1 second before the start, until the vehicle comes to a stop.
When the vehicle exceeds 11 mph (5ms) and along with a working tach signal, inputted into the CL1 data box.
No problem. The D3 app will still utilize Google maps when overlaying driving data. The map will be zoomed out more than if Racepak pre-mapped.
