MMTuning Custom S300 Basemap Swap File

Got a new setup or just need a clean basemap to get your build running? Our custom MMTuning S300 Basemap File is built from experience, tested across countless setups, and tailored to get your engine started, running smooth, and ready for dyno or street dialing.

🧠 Compatible with Hondata S300 v1, v2, and v3 only
📥 File sent to your email within 1 business day
💻 No physical product — just pure digital calibration
🧰 Customized to your engine specs and hardware

Whether you're all-motor, boosted, running big injectors, or switching fuel types — we’ll configure the file based on the exact info you give us. You must provide your full setup specs in the order form.

This is a basemap only — built to get your car running reliably for break-in, troubleshooting, or prep before final tuning. It is not a fully dialed dyno tune. Because every build is different — from fuel pressure and compression to wiring and sensor conditions — we can’t guarantee perfect results without a live tune.

⚙️ Setup Options (you’ll fill these out during checkout):

  • Engine Type – Pick your swap or setup. If it’s not listed, choose “Other” and describe it in the notes.

  • Aspiration – All-motor, turbo, or supercharged

  • MAP Sensor – Must match what’s installed on your engine

  • Injectors – Match your installed injectors for accurate fuel delivery

  • Launch Control RPM – Set your launch limiter (optional; speed sensor must be functional)

  • VTEC Engagement – Choose your desired VTEC crossover or let us decide

  • Rev Limit – Safe and sane or full-send — your call

  • Shift Light – Check engine light shift indicator option

  • Knock Sensor – Enable if your ECU supports it

  • O2 Sensor Settings – Enable or disable based on your emissions and wiring

  • O2 Heater Circuit – Typically only needed for 4-wire sensors on emissions setups

📩 Need help flashing your S300 basemap? We’ll send a link to our upload guide with your file.
