These rules have been developed to govern tuning discussions. Posts and posters running afoul of these rules will be treated harshly. These rules may change.
1. Board members and administrators need to respect laws and act fairly. Together, we will endeavor to promote honest behavior and discourage the opposite.
2. Any information/knowledge that has been obtained by an individual will not be shared if that person does not have a legal/written right to do so. "Information" includes any vendor's DAMOS files, strategies, screenshots, proprietary software. The tune you purchased (or that came with your car) may not be yours to share; it is certainly someone else’s work product. If you were employed by a tuner and have a confidentiality/non-disclosure agreement, obey it. Members assume personal liability by acts to the contrary.
3. Any vendor believing that information is being posted illegally or in violation of agreements should use Report Post and provide factual/legal basis for the objection. Threads/posts may be locked/hidden during discovery.
4. Members need to recognize that there are grave inherent risks to using information garnered via these discussions. The Board and Autoguide assume no responsibility for what Members do to their cars as a consequence (e.g. bricking their DMEs, breaking their vehicles, resulting injuries, etc).
OP's original post now follows:
So a few weeks ago I stumbled upon this thread: Comprehensive MSS54/MSS54HP DME Information
Some of you might know/seen that I already started to attempt to find some of the maps/tables myself.
Our DME has well over 2,000 maps/tables/values but only about 100 need to be altered to make a custom tune.
The MSS52, MSS54, MSS54HP are all remarkably similar, so a lot of the work that has been done on m3forum will carry over.
With the blessing of the p0lar on m3forum I've decided to get the ball rolling over here.
Its quite easy to read/write your DME with a ~$20 cable called the Galletto 1260.
Quite a few others manufacturers' DME/ECU has been cracked and reverse engineered already e.g. Subaru, GM, Mitsubishi, Ford.
If we can map out the DME then any competent tuner will be able to write tunes for us.
So who wants to help out? Who knows how to use WinOLS or Tuner Pro?
Personal note: this is my 4000th post!
