I have today finished building my own MPGuino based on the these schematics

/trunk/mpguino/ - opengauge - Open Source Fuel Efficiency Instrumentation - Google Project Hosting (the 13 version)

I plugged it in and got no injector pulses though the VSS was working. After quite a bit of checking I realised that I had been here before. I needed to replace the 50K input resistor on the injector with a 1k. See my previous post

That sorted things, and is what I had on my test rig cobled together when I first tried to get this working. Im now going to switch the 50K VSS for a 1K (perhaps 1.2K what the hell).
