I've been looking into whether there is a PC-based datalogger out there which will work on our cars, which as we know are not OBD-II compliant but use the Mitsi MUT-II protocol. While trawling round the web I came across some software called Evoscan, which claims to work with all 1996+ Mitsi's, including those that use the MUT-II protocol. This requires an OBD-II cable with a USB-Serial adapter, and I ordered the OpenPort 1.3 Mitsubishi cable from Tactrix ($89 US). I downloaded the Evoscan software ($25 US), but first attempts with the cable and software were unsuccessful, with connection timeout errors. Then I noticed something on the website about the Evo IV requiring pins 1 and 4 on the OBD socket to be joined. Looking into this further, it became apparent that all that is actually needed is to ground pin 1 as per the manual procedure for extracting fault codes from the VR-4.
I inserted a bent paperclip into the back of the OBD socket where the wire for pin 1 joins the socket, and grounded it out on the metal frame which holds the socket itself. This time, on connecting the cable and running the software, it connected without a problem. Screenshot of Evoscan is below:
There are 2 other pieces of software which I've also found that are compatible with this cable and I've tested with the VR-4:
Mitsulogger (which is freeware):
and EcuEdit (demo version with nag screens):
Enjoy!!
