good product for OBD-II interface for performance – A301 Vehicle Car OBD Multi-Function Trip Computer - Black (3.0" LCD) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Purchased for display of fuel consumption, after some reprorgamming and two test trip, very useful tool for the two Gasoline Trucks, but not accurate for Diesel (as expected): 2003 Ford F250, 2000 Explorer SUV XLS and 2005 Dodge RAM Diesel Cummins 5.9. Once the 330value was adjusted using 500Km tank-fill tests, the trailer load factor was accurate around 2% and I believe the "instantaneous value": the air intake measures also helped me tune the Fords cold air location a bit
expect to study the vehicle economy using the tank-fill method calculations in the brochure over 1000KM to "tune" the device. Write it down; the A301 has no memory between vehicles: you always start "fresh" from default
very useful for one work vehicle at a Farm in CANADA and helps to tune out economies to about 10-15% which at $1.30Cd per liter can be significant over a longer period of time
good device to tune up the vehicles economy, modify the air flow, habits, load factor in a truck, night time use required me to find the backlight and contrast settings; the manual is poor, fast & easy to hook up with only the one plug
