  • The free account will allow for the creation of two Car projects and downloads of free files, such as OEM based 3-stage tunes for MSV70 & MSV80.

    Future tiers will include "Advanced" and "Pro" which will include significantly more functionality, including custom tuning and the use of the Bimmerlabs tuning database.

  • Latest Update: N51 tunes! (and GM912 update)

    Ok, so for whatever reason - lately I've received a ton of requests for N51 tunes - custom or otherwise. Before, these came along so seldomly, it wasn't worth the effort (like 3 a year, maybe).

    I think I got 3 requests today alone. On one hand, I don't have something specific already made. On the other hand, we already have it mapped out, and have an RSA delete available. So, expect an update soon - I haven't gotten to all the requests, but I have seen them and am aware of the demand.

    On the GM912 front, we have 330i flashes available for them - but it turns out, there are two EGS computers with different programs, so we pulled the files until that could be sorted out. Preliminarily, the difference appears to be cars with paddle shifters vs those without - so once that's sorted, expect those to be available again.

  • About Us - What is Bimmerlabs?

    Several years ago, DIY tuning of cars like the E46 M3 was basically impossible. The information was locked away, and something simple like coding out an error code would cost hundreds of dollars.

    A group of enthusiasts from all over the world got together and 'cracked' the DME - basically, we just figured out what made it tick. Now an EWS delete/flash tune that used to cost $3000 is less than 1/10th that price.

    As we were working on the E46 M3 computers, we started to develop skills in things like disassembly and hex editing. We were also using programs like TunerPro extensively (and somewhat, WinOLS and programs like it). However, the abilities of these programs left lots to be desired - building an XDF for TunerPro its very time consuming (MSS54, which I'd consider 'simple' by modern standards - has ~4,000 unique parameters), and it has bugs and lacks features. WinOLS has more power, but it's locked up and expensive.

    At some point, we realized automated XDF generation made a lot more sense. But another issue is for each car, there could be 20 or more program variants - which means every one of them has different addresses, or 'offsets', for each parameter. Each parameter for each program version had to be found by hand - again, time consuming and nearly impossible to do manually.

    We started Bimmerlabs because existing tools could not effectively solve these problems. TunerPro can hardly even handle the amount of parameters on a modern car (10,000+), and if you have files from two program versions you can't do anything with them. WinOLS has some abilities to align files from different programs, but licenses are expensive and the scale of it's abilities didn't fit our goals.

    Our Tools

    We built some early tools to solve these problems - an XDF generator that could parse unlimited amounts of parameters, a binary search tool that could find missing parameters across different program variants, tools to correct checksums, RSA signatures, and generate files for flashing - but the rub was, they were only available to us and were not friendly to use (most of them being command-line only scripts).

    Bimmerlabs.com is basically a web-based API for accessing these tools, and a launch-pad for things like custom DIY tuning and flashing of a large number of modules.

    Currently, the 'beta' version (0.9.10) of Bimmerlabs has a number of capabilities - although these aren't all exposed to the public.

    • Automatic Checksum correction
    • RSA signature correction (for some models) - meaning no 'boot code' mods are required
    • Reading and Writing of BMW proprietary 0da/0pa flash files
    • Converting binary files to BMW, hex, or .bin format (with checksums corrected etc)
    • Managing custom and 'stock' files for specific BMW models (even for one engine, like the N52, there are dozzens of variations for each model)

    See our list of fully supported DMEs here.

    The current tools allow us to offer 'Stage 0' tunes for specific N52B30 powered models - which allow you to run a factory '3 stage' tune on lower-powered models at no cost. For example, a factory '330i' tune for the E90 328i never existed - but we have created one! We can also offer several other services that aren't available for DIY use - swap tunes, EWS deletes, etc.

    This is just the beginning of what we are working on - the eventual goal is custom DIY flashes for basicaly any BMW model, including BMW transmission tunes. Editing of files will be done through the Bimmerlabs API - no external software neccesary.
