I am new here...thanks for all of the great info. I have recently started a new job requiring a 140 mile commute at times. I purchased a 2002 Honda Civic and have been pleased with it's efficiency but always want more MPG's.
I thought I'd start with a Scangauge II (purchased from Ecomodder) and received it today. I plugged it in to the OBDII port on the Civic and it powers right up but never connects. It just says "connecting.." but it never actually connects.
I unplugged the battery for 15 min, checked fuses, the cig lighter works, pulled the ECU fuse for 10 min, sprayed OBDII port with contact cleaner and am at wits end.
Any help would be greatly appreciated!!
