I personally would buy a handheld scanner. I got one for $80. Its a cheap one, but it does everything I need. It reads the codes, and lets me delete them.

this, combined with Digimoto software, will allow you to watch realtime statistics (intake temp, coolant temp, RPMs, speed) along with graphs of all the prementioned while driving from Point A to Point B. Allows you to compare RPM's with MAF Rate to see what RPM's might give best Air Flow, etc.
You are only able to see if you have a CEL or not nana.gif

found some info about OBD protocols:
An OBD-II compliant vehicle can use any of the five communication protocols: J1850 PWM, J1850 VPW, ISO9141-2, ISO14230-4 (also known as Keyword Protocol 2000), and more recently, ISO15765-4/SAE J2480 (also known as CAN).
As a general rule, you can determine which protocol your vehicle is using by looking at the pinout of the DLC:
Pin 2_______Pin 6 _______Pin 7 ______Pin 10 _______Pin 14 ________Pin 15 _______Protocol
MUST________ - __________ - _______MUST___________ - ____________ - ________J1850 PWM
MUST________ - __________ - ________ - _____________ - ____________ - ________J1850 VPW
_ - _________ - _________MUST________ - ____________ - ___________MAY ______ ISO9141/14230
_ - _________MUST _______ - _________ - ___________MUST _________ - _________ISO15765 (CAN)
In addition to pins 2, 7, 10, and 15, the connector should have pins 4 (Chassis Ground), 5 (Signal Ground), and 16 (Battery Positive).
<span style="font-size:12pt;line-height:100%">UPDATE!</span>
According to WebTech pin #7 is K-line, pin #15 is L-line. So our OBD-2 protocol is ISO9141/14230
I found a site with nice DIY about OBDII to PC cable.
http://www.planetfall.com/~jeff/obdii/
It says that that interface will support ISO9141-2 / SAE J1962 (OBD-II).
Schematic looks very simple and should cost not more than $10.
What do you think?
Who wants to try?

Yes they do, but they use different software so you won't be able to read a Korean spec ECU with US software.
