Frequently Asked Questions
Does this cover both pre-facelift and facelift E31 models?
Yes. The software covers the complete E31 production run from 1990 through 1999, including pre-facelift 840i and 850i variants alongside the updated 840Ci, 850Ci, and the high-performance 850CSi equipped with the 5.6L S70 V12.
Is the 850CSi’s S70 V12 covered in full detail?
Absolutely. The S70B56 engine fitted to the 850CSi is fully documented, including unique motorsport-derived components, individual throttle body adjustments, and the higher-output engine management calibration specific to that model.
Are wiring diagrams included for the E31’s complex electronics?
Yes. Interactive circuit diagrams cover the full E31 electrical architecture — including ABS/ASC traction control, EWS immobilizer, multi-information display, automatic climate control, power seat modules, and all lighting and audio circuits with component locator functionality.
