You can download stock ROMS to look at from, just scroll to the bottom half of the page, fnd the year and model, and the most current revisions should be there.Īll there is for the Baja are the two that i have posted for the 05 5mt baja T. To open the ECU ROM images, you need to have them downloaded individually and in a folder somewhere. When you open enginuity go to edit and then definition manager and make sure it is following the correct path to your definition file. when you download and unzip it you need to move it to the enginuity folder. It must be in the enginuity folder and is labeled 'ecu_defs.xml' the newest definition file is 4,777 KB (large because it inclueds all of the CEL's.) If the file is not there for osme reason you can download it seperatly from. When you download the most recent version of enginuity, the most current definition file is included. Where are these definitions? And what are they? How can I play with the software? Also the car is auto, would that matter? Now I wanted to look into enginuity for the maps etc and I cannot open anything. You can do it for $75 yourself using the same free opensource tools that the WRX guys do.

If you are interested I can give you some of my maps to look at, all you have ot do is download the free software to view them. You can also read and erase codes with this and turn off CELs (if you go catless for example).Īnd you can do datalogging with programs like tari ecu explorer (also free)

So I have made a baja specific stage II STi map to run my baja T with VF39, sti uppipe, catless downpipe and sti intercooler. I basically changed all my table axis to match the 05 sti the best i could (some tables have more/less resolution) and from there based my maps on sti maps.

You obviously have to know what you are doing to some degree. Then once you have it you can edit it in a program (I prefer Enginuity), At this point ide reccomend making a copy of your ecu as a backup. This lets you read and write to your ecu. Order the tatrix cable, go to and download ecu flash.
