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.

Anyways, I just finished the v3.0 board design which:

  • Fixes the pin out on the wiring harness connector
  • Adds a 5mm LED for low fuel light warning
  • Adds some holes in the PCB for adding standoffs to support the LED display
  • Removes the terminal block option

Most everything should be pretty self explanatory, but I wanted to take a minute to explain the last item. The first version of the board didn’t have the OEM connector for plugging directly into the stock wiring harness, instead I had a terminal block to connect the wires. I ended up removing the terminal block from this version because:

  1. I figured the majority of people would use the OEM connector
  2. I was a bit worried about the reliability of using a terminal block- especially in racing
  3. Adding the fuel light meant less available PCB space and needing to add a 6th connector
  4. People can order the board without the OEM connector and solder directly

Anyways, I just submitted the order to OSH Park today- should be a part of March 27th’s panel, and so I should have the boards back by mid-April.
