v4.1 board design finished!

I’m happy to announce I’ve finished with the latest design of the SV650 ECU Decoder which has a number of improvements:

  • Add button for switching the display modes
  • Add support for detecting “very low fuel” on 2005-07 models
  • Improve battery voltage measurement circuit
  • Small tweaks to the layout and silkscreen

The board design has been sent to OSH Park for fabrication and hopefully I’ll get them in about 2 weeks.

Here’s a rendering of the new PCB design:

Update: So some testing of this board is showing some problems, including a possible problem which causes the Teensy board to be damaged, so I’m currently suggesting people not use it!

Parting out 2008 Ducati 1098S with 916 miles

Bought this bike salvaged for a project. As you can see, it had a lowside on the left side. I kept the front wheel, forks & frame as they were straight. Selling all the parts I don’t need and that are in good condition. While some of the parts here probably don’t belong on a show bike, everything here is perfectly usable and I’d be using it if it was useful for my project.

All parts are in very good condition unless otherwise mentioned; I threw away anything that was very damaged. Please be sure to check the pictures for more info.

The 2013 AFM Season in Review

So I had planned on doing regular reports after each and every AFM round during the 2013 season. But after missing the first three rounds due to mechanical problems and then a constant struggle to not just develop a new bike, but make it reliable enough so I could just concentrate on my riding, I ended up having a really hard time talking about the project in the kind of positive manner that I wanted to.

Not to say I figured this year would be easy- building a one-off custom race bike is of course going to be fraught with lots of challenges, but frankly, the problems I ended up having left me exhausted and the last thing I wanted to do was share them with the world.

In the end though, I wanted to make sure to have a record of 2013 and take the time to thank my sponsors and everyone who helped me if for no other reason so that when things go better next year we’ll be able to look just how far things have improved.

So, long story short, back in October 2012 we started off with this poor 2008 Ducati 1098S with less then 1,000 miles:

Doner bike

SV650 ECU Decoder Part 4: Third time is the charm?

Part 1 is here.
Part 2 is here.
Part 3 is here.

So my v2.0 boards were a complete dud.  Turns out some how I messed up the design and ended up wiring up the connector to the wiring harness backwards so nothing works.  Wasn’t a complete disaster- I was going to have to do another revision of the board either way, but it does slow things down.

SV650 ECU EFI warning decoder/dash replacement

So I finally finished the design of my very first PCB and placed an order with OSH Park to get some samples. The basic premise is I needed a way to decode the data stream from my 2nd gen SV650 ECU to know when there is a problem with the fuel injection system with the race bike. Also, ideally, I needed a way to know what the specific error codes are.

Normally you do this with the stock dash, but I wanted to use my GPX Pro dash and didn’t want two dashes on my race bike. Unfortunately, the PCB on the dash is just one large unit (including the tachometer) and so there wasn’t an easy way to just use the parts I needed (a red idiot light and the LCD which displays the error code).
