Suzuki SV650 ECU Decoder
This is the Arduino code (for a PJRC Teensy 2.0) and necessary CAD/schematic files for creating a PCB to creating your own 2nd Generation SV650 ECU Decoder to replace the error lights & codes normally displayed by the stock dash unit.
This supports the following:
- Oil pressure warning light
- Neutral light
- EFI warning light
- Low fuel light *
- Display the water temp from the the stock water temp sensor
- Ability to decode EFI error codes from the SV650 ECU
- TPS adjustment indicator **
[*] Note: Untested.
[**] Note: Normally the 4 digit LED display shows the water temp. To show the TPS indicator or ECU error codes, you’ll need to use a “Suzuki diagnostic tool” (aka a paperclip) to short two wires per the shop manual.
