A few of you might have noticed a couple ports (which look like this) http://i6.photobucket.com/albums/y214/ezzab69/dataconnections.jpg
beneath the left hand side of your steering column and wondered what they were for. If you did and thought they’re diagnostic ports, then you’d be right! :) (It looks like a ODBII compliant port, but it isnt because it uses an entirely different protocol, i think its called the MUT protocol, and its what mitsubishi uses in thier factory and service centres)
I got my hands on this cable which connects to these ports to my laptop via a USB port.:D

It offeres realtime readouts of heaps of things like Throttle Position, Engine RPM, Speed, Battery Level, Airflow per engine revolution, Intake Air Temp, Timing Advance, Barometer readout, Oxygen Senser readouts, Fuel Trim (Low, Mid and High), Fuel consumption, and heaps more. It can also be used to view and/or clear DTC's (Diagnostic Trouble Codes). Also the diagnostics can be shown on graphs or on graphical guages which you can build youself, and logged diagnostics can be played back as recorded telemetry on the table, graphs or graphical guages.
I thought it would be interesting to be able to monitor some of these readouts, but then after playing with it for a while i started getting over confident and started tweaking settings which i really didnt know what they did.
I didnt seem able to change anything performance wise, but i did manage to cause 2 diagnostic trouble codes to be displayed on my car's dashboard (blinking engine light and blinking antilock breaks light). The car even got to the point to where it wouldn't start, it would start then die after 1 second of being on :rant: ! so i started freaking and put all the settings back to how they were, and now the car is back to normal, except i think the idle is slightly rougher than what it used to be, i might just be over analysing how the car runs though. Now i'm sort of scared to use the cable and its now sitting in my room!
A couple other things, it says it should be able to moniter the abs computer but i didnt try it, though it could be interesting. AND it has an ON THE FLY dyno feature which i haven't tried either because i'm not into superfast illegal driving atm! (I dont have any demerit points left and i'm on a 12 month no points agreement)
Here's a short video of what i did tonight, sorry about the quality, i used my phone camera and its at night.

Just thought this might spark some interest in some people.
