Planned Future features via firmware update:
- Saving ~30 minutes of datalogging information to onboard EEPROM, 10 samples/second
All the hardware is in place for the new functionality, it should just take a new firmware to make them work. I can not guarantee that all the planned features will materialize, so do not buy this based on the planned future features.
Additional Parts Required:
You will need to purchase the following to complete your wideband
- Bosch 4.2 LSU Wideband Sensor, info here
- Harness for sensor if you do not want to use the included terminals, info here

60 day money back guarantee of full purchase price, including shipping.
Misc
Serial communications for programming the analog outputs, firmware upgrades, real-time datalogging and EEPROM downloading requires a PC with Windows 98/XP/Vista, Microsoft .Net Framework, and available serial port or serial-to-usb converter.
For easy debugging, there are 27 debug pads clearly labeled on the underside of the PCB. Schematics and debug guide are included in the documentation.
