So I’ve been spending my time working on the firmware running on the Teensy board which does all the ECU decoding. I’ve added support for displaying water temp and ECU error codes on the four digit LED display as you can see here:

As you can see from the video, I’m decoding the temp in Fahrenheit, but adding Celsius support would be really easy. All of the SV650 error codes; including the TPS adjustment indicator is supported. Right now the only real difference between my decoder and the stock dash is that you don’t need to short the two wires to read the error codes when there is an error- I automatically switch to displaying the codes when there is an error condition. It would be easy to support the default behavior of just turning on the EFI warning light and only showing the codes when in “dealer mode”.

All buttoned up in it’s enclosure:

I hope to be able to take video of the box on my race bike next week!
