I just got my new MPGuino straight from opengauge.org in the mail a couple of days ago. I hooked it up to my '93 Geo Metro Convt today and I am seeing 999 MPG instant. I believe I used the default setup on everything with the exception of vehicle weight (I think I put something in like 1600 or so). Anyway, if I am driving 35 MPH and go to screen #1 it shows:
9999/"working MPH"
9999/"working distance"
If I go to screen #8 it shows:
1.4/G0000000 (never changes)
1.4/G0000000 (never changes)
Can anyone help me troubleshoot this thing?
I have the unit hooked straight to the ECU (well, using the wiring harness at the ECU). You can see my install here (work in progress):
