You may eventually decide that you want to donate to the guys who are working so hard on developing the project, but other than that there are basically only two things you will need to for getting started that cost a small amount of money money other than a laptop.

RomRaider is an absolute bargain in the world of ECU tuning, in that most of what you need to use it is available to you free of charge.

**To download many of the resources you will need (described below), you will need to join this forum so you can download the needed files from it. In case you came to this Wiki first, and haven't been to the forum, the main forum for developing RomRaider for BMW MS41 DMEs is here: Some of the nuances of using RomRaider for a BMW DME are a bit different than the situation is with a Subaru, so oftentimes the information that we can get from the main RomRaider forum that applies to Subaru tuning does not apply to us. Currently there is only a 'developing the definitions and reverse engineering the software' forum (paraphrasing the purpose of the forum), so it can be a little difficult for a person to come up with all of the necessary information to setup RomRaider and start using it to tune his or her Bimmer. One downside of RomRaider for us Bimmer fans is that so far there hasn't been an actual tuning forum for it yet. This is a bit of work though, since you normally have to move over the data from a lot of your maps into the 41.2 tune (.BIN file). Still, the 41.2 is considered to be the best of the bunch, and many people who have lower numbered versions of DMEs flash the entire 41.2 tune into their DME to gain its features. The DME MS41.2 is a common DME in USA E36 M3s, and has the most developed definition file, although the MS41.1 ID60 and a couple of other versions are not too far behind. RomRaider needs individual 'Definition' files for different versions of ECUs or in our case 'DMEs,' see below.ĭifferent DME versions' definition files are developed to differing levels of completion because the coding in them is different (but similar in many cases I guess), and therefore they require individual reverse engineering efforts to develop. Luckily for us, not too long ago some geniuses who like E36 M3s started developing the definitions for the MS41 series of DMEs (41.0, 41.1, and 41.2). The basic RomRaider tuning interface software also includes an additional datalogger screen, and some very advanced functionality with it, but more on the logger function later. INTRODUCTION:RomRaider is a great little free engine tuning program, developed originally by a community of Subaru guys.
