Yes, the mpguino is a kit and does not use either OBDI or OBDII; it connects directly to the car's speed sensor, injector (just one) and switched voltage for its power and signals. It does NOT connect into or through any OBDI or II connector.
Got mine in the mail yesterday! Just in time for 4+ hour trip (errand) after work that I was dreading. Setup took two minutes and my girlfriend actually wanted to talk about FE
Am I correct in thinking you have basically four options for MPG display?
1. Factory-installed instrumentation
2. MPGuino for non-ODB, about $50, 4-wire install
3. ScanGauge2 for ODB2, about $150, plug&play
4. UltraGauge for ODB2, about $70, plug&play
So if you don't have ODB2 port, your only option is MPGuino? And besides supporting Darin and Ben and this website, what other advantages does SG2 offer over UltraGauge that is half the cost?
