AutoSelect Japan

AutoSelect Japan is an independent tuning and performance workshop in Sakai, Osaka, focusing on GT‑R/R35 tuning, ECU remaps, 4WD dynamometer measurements and carbon‑fiber work. The company operates a showroom and garage with on‑site sales of tires and performance parts.

You’ll find a factory‑style setup with diagnostic and dyno equipment, sales counter for parts and scheduled opening hours; staff contact details and address are published on the official site and mapping services.

You’ll arrive at a combined showroom and garage and either talk with staff about parts/tuning or have your car fitted and tested.

What you’ll see and do:

• Consultation about goals (power, drivability, parts) and a written estimate.
• ECU tuning and dyno runs on a 4WD dynamometer to measure power and tune maps.
• Parts fitting (tires, carbon fiber components) and basic pre‑inspection checks.
• Pickup after testing; expect technical discussion in Japanese—bring photos or specification sheets if helpful.

Best way to plan:

• Call ahead to confirm staff availability and book dyno time (Tel +81 72‑363‑0383).
• Allow several hours for tuning + dyno work; bring vehicle registration and any relevant aftermarket part details.

• Open hours vary by department; factory/sales hours are published on the official site.
• Closed regularly on Wednesdays and may close for events or races.
• Staff may primarily operate in Japanese; arrange language help if needed.
• Bring vehicle documents and any existing ECU/part paperwork.
