Hey all. I think this will be my first post and I have to say how mind blown I am that so many people so generously donated their time to this project. I never woulda thought this was possible. We got some smart (and seriously generous) ones here!
I'm posting in this thread because I too have a (94) VX. I just built up my iduino mpguino and I'm itching to get it hooked up.
I'm at this point:

Installation notes:
For Identifying where to tap into the fuel injector:
1. turn on the ignition, leave engine off.
2. Unplug an injector.
3. With a voltmeter, measure the voltage on each injector connection. One should be 12 volts and the other should be more like 0. You will want to tap into the one that is at 0 volts.

..and getting a little stuck. With the ignition on,
all of my injectors are reading 12 volts. Has anyone else run into this? What did you do?
According to
this diagram, the VSS signal comes in at B10 on the ECU. Can anyone confirm that one? Also, would you happen to have an ECU pin for the always-on +12 volts? Is this even where I should be getting the always-on +12 volts from? I suppose I could dig around with my voltmeter, but if someone had it handy, that would be wonderful.
Did anyone include fuses or other safety things?
Lastly, does anybody have all the nice calibrated MPGuino settings?
I hope that's not too many questions for a newb to throw down in the beginning. As you can see, I am very green, but very excited to learn from you all. Thanks in advance!
