If starting from an arduino, there is an archived version of the original arduino code here (which probably needs an archived version of arduino ide):

My first test was not a successful one. Quick jaunt to the Taco Bell for some dinner, and the MPGuino's data log looks all wonky.
Here's the setup
96 Civic EX - Automatic and Stock
VSS wire - C18 (Blue/White)
INJ1 wire - A04 (Brown)
Breadboard is wired with 22AWG single strand
VSS and INJ wire are 18AWG multi strand
VSS/Pulse Mile - 8208ul
MicroSec/Gallon - 0272500000ul
InjectorDelayuS - 72ul
These settings were taken from a 97 DX Coupe Auto (Wiki)
The following is the data collected. I pulled out a section where I was doing 40mph consistently on flat road.

Can anyone see any discrepancies?
Power/Ground is soley from my laptop to the arduino. Is this an issue? I figure no since i'm not requiring power for anything other than processing. I just don't know if the lack of chassis ground is my issue.
