The world seen through one car — BMW E46 M3 maintenance, diagnostics, DME tuning, and the philosophy of keeping it for the long run.
A site centered on the BMW E46 M3 — maintenance, diagnostics, DME coding, mapping, and measurement for keeping a beloved car running well for the long term.
It shares hands-on know-how for going DIY: CSL conversion, M-track mode coding, VANOS settings, and drivetrain failure and cost guidance. Through recording, planning, and sharing, the goal is to enjoy ownership itself.
Inquiries are handled via the TSUNAGI Discord. Based in Hokuto, Yamanashi, with intentionally limited intake.
