OK I found the yellow/green wire under the dash on the drivers side above the fuse block ( the ECU is right there too). That made everything work much better and I was able to get a rough speed calibration for my car of 8100 pulses ( I went 50 MPH on the speedo and tried to get MPGuino to indicate 54.16 for the 8.333% difference) close enough for now.
It did freeze up on me once and there is one part on the back that I noticed gets a little warm is this normal or might I still have some connection problem?
So, from here, if I understand this right, once I get actual mileage from the next tank I start adjusting the injector input until I can get actual and MPGuino mileage to match right?
