OBDII Automotive Scan
Tool and Virtual Dashboard
Recently I came a cross an useful tool
for our 993s, it is a small investment compared to the amount the data
and information it can provide. I have tried the scan tool on both
of my Porsche 993 and the BMW and it worked well for both cars.
The OBD2 scan tool basically is a cable/software
combination that can turn your laptop computer into a portable flight data
recorder for your OBD2 equipped car, it does a lot more than just record
data, it can tell you the fault code that set off your check engine light
and the o2 sensor readings in real time, a very helpful feature for someone
who is tuning their car.
The OBD2 scan tool can be purchased directly
from Alex on his web site at www.obd-2.com
mentioned that you heard about this product from my web site and Alex may

|Here are some explanation
in regards to OBD2
OBD is a abreviation for
On Board Diagnostics. OBD-1 is in reference to Title 13 California
Code 1968 tiltled "Malfunction and Diagnostic System for 1988 and Subsequent
Model Year Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles
with Three-Way Catalyst Systems and Feedback Control." filed on 11-15-85.
This required cars sold in California to have a on-board computer processor
for on-board self diagnostics of computer sensed emission related components,
fuel metering device and EGR (exhaust gas recirculation system). A partial
or total malfunction that exceeded exhaust emission standard would illuminate
a MIL (malfunction indicator light) and provide on-board indentification
of the malfunction location. To provide malfunction location information,
codes are stored in on-board computer memory. To read codes manufactures
use methods, such as flashing MIL light or various serial data protocols.
OBD-2 is in reference to
Title 13 California Code 1968.1 titled "Malfunction and Diagnostic System
Requirements-1994 and Subsequent Model-Year Passenger Cars, Light-Duty
Trucks, and Medium-Duty Vehicles and Engines. filed on 8-27-90 to Air Resouce
This requires a standard
electrical connector, open source standarized diagnostic trouble codes
(DTC), data, and communication protocol with more specific self-diagnostic
on-board monitoring of emission malfunctions.
