Has anyone tried a "CarChip E/X OBD recorder" ?

This device is smaller than a cigarette packet, but plugs into your car's OBD connector, and records up to 300 hours of data, which can be played back via a USB connection into your PC. They cost around AUS$286
There's a cheaper 75 hour version available for $217.80

(There's a review in the October issue of "Silicon Chip" magazine.)

Has anyone tried one of these in a Liberty?

There are three basic OBD-II protocols in use, each with minor variations on the communication pattern between the on-board diagnostic computer (ECU) and the scanner console or tool. While there have been some manufacturer changes between protocols in the past few years, as a rule of thumb, Chrysler products and all European and most Asian imports use ISO 9141 circuitry. GM cars and light trucks use SAE J1850 VPW (Variable Pulse Width Modulation), and Fords use SAE J1850 PWM (Pulse Width Modulation) communication patterns.

So if it can read any of these it should work. Remember this is only a read and you will not be able to change or tune any part of your ECU.

Download a copy of Ecuexplorer and a cable. A lot cheaper.
