Main Page

Welcome to the B58 wiki: the site dedicated to tuning BMW's fabulous B58 engine. The emphasis is on understanding the DME software rather than how to choose a new turbo. As such, there will

• reference information on individual tables, with their descriptions, the units and the tuning goals for which you might need to change them.
• tutorials on tuning goals like creating a stage 1 tune, calibrating a turbo upgrade, setting up port injection, etc.
• calibration templates for specific hardware, like the DAW Flowmax, Pure 800, etc. If you are a self-tuner who has spent a hundred iterations dialing in their turbo, we want to hear from you!

B58.wiki aims and anti-aims

This is a site for helping people understand and create safe and performant tunes. A blown-up B58 is a bad thing. Any information that helps people to create clean and correct tunes is a good thing and we welcome it. On the other hand, we do not welcome comments defaming individual tuners or their work or pirating of custom or OTS tunes.

Among the B58 community, there are those who want to keep their car stock, those who want OTS tunes, those who want professional tuners and those who want to tune their car themselves. Don't do anything on this site that would piss off other groups in the B58 community.

Contributors

Contributions are welcome from anybody. It helps if you understand B58 tuning but, if you do not, there are other ways to help such as through proof reading, pointing out stuff that does not make sense, stylistic improvements to icons, linking or adding diagrams.

Specific contributions that would be welcome:

• Articles on specific topics like fuelling, PI, etc.
• A high-level article on understanding torque-based engine control that has a B58 focus (currently, the one linked from this wiki is ford ecoboost focussed).

Status of this site

You can learn a lot about the B58 DME here but the site has to evolve further before it becomes a definitive reference for B58 tuning. If you would like to see this happen faster, then find a way to contribute.
