About Classic Auto Diagnostics

Automotive vehicles manufactured after 1996 are all equipped with some degree of On-Board Diagnostic (OBD2) capability. If you own a vehicle produced prior to that date, troubleshooting issues can be challenging, and critical system failures are often identified too late.

Challenge
Here at Classic Auto Diagnostics, we believe in preserving the classic nature of older vehicles while embedding the diagnostic capability of modern technology. We were determined to develop a method of monitoring essential operating parameters of non-OBD vehicles without modifying the original ECU.
Solution

Solution
At its core, our solution provides visibility of various system components either locally via a 5- or 7-inch touch screen, modern OBD app, or anywhere in the world through our cloud service subscription.
System Features
Upper and lower sensor thresholds can be manually set or automatically learned over a period of time. Once set, baseline deviations can be logged locally to an on-board SD card with the driver informed through visual or audible alerts.
Vehicle health can be captured via snapshots, where system parameters at any given point in time can be logged to the SD card. Configuration allows local logging:
- At a given cadence
- Upon an alarm condition
- When up to three sensor thresholds have been exceeded.
Onboard GPS permits vehicle tracking and visibility of other generic GNSS data. Minimum number of acquired satellites can be set to ensure accurate data is used for speed readings (when sent to factory speedometer)
Any changes in the vehicle's horizontal rest angle, or detection of GPS speed while ignition is off will result in an SMS alert and immediate upload of GPS coordinates.
Native ELM/OBD emulator provides real-time wireless monitoring using "Torque" or "Car Scanner" off the shelf apps. A combination of generic ISO15764 and custom PIDs are supported, along with the ability to view and erase logged DTC's
Cellular capability permits the upload of all parameters (every two seconds) to a cloud-based database for either real-time viewing or historical reference. Statistical analysis can be performed to identify historical trends, potentially identifying anomalous behavior that may not be immediately evident.
Low power consumption (< 10mA sleep mode will not result in any material difference to battery drain.
Road and engine speed can either be passively monitored, or intercepted, translated and sent back to the original speedometer or tachometer. If your wheel circumference, or engine firing (4,6,8 cylinder) has changed, entering an offset and translating the input will ensure correct speed is shown using the factory displays.
GPS speed can also be used as an input for redirection to the native speedometer. In addition, a test signal can be generated to assist in visual calibration.
Adjustable 3:1 voltage division for analog and digital sensors permit up to 15v on all voltage protected inputs.
