- One 0-10v input channel
Digital LED display Gauge
- 4 digit LED
- Selectable refresh rate
- Brightness adjustment via variable resistor
Multiple Digital LED display Gauge Support
JAW 1.041 Supports daisy chaining of upto 4 LED display Gauges to show; AFR/Lambda, EGT, Boost, RPM
More info about the Multiple LED Display Gauge support is available here
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.
Sourcing Components/Parts:
You will need to purchase the following to complete the kit. Before you order the components it would be a good idea to read this first for mod ideas.
- Bosch 4.2 LSU Wideband Sensor, info here
- Harness for sensor if you do not want to use the included terminals, info here
- EGT Probe, info here
- Wires, use multi stranded with a rating of 3 amps
- Component List for JAW 1.041, I recommend you buy them from www.futurlec.com as they offer the best prices. The cost of the components is ~ $10 USD
- Components List for Display 1.01, the cost of the components is ~ $6 USD.
- The case is available from here for USA and here for outside USA
Warranty
There is a 1 year warranty on the microcontroller and PCBs.
Refunds
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.
