How it works
- Order — send your order through the contact form. We confirm price, method and payment within 24h.
- Tell us your car — VIN, engine code, mods, fuel and how you want it to sound.
- We calibrate — your file is written in Tokyo for your exact configuration, typically 24–72h.
- Flash it — remote: we guide you through flashing. Mail-in: your ECU comes back ready.
- Log & refine — send a datalog after your first drives and we refine the map. Support is engineer-direct.
Before you order
How is the tune delivered if I’m overseas?
Remote flash: we deliver your file and guide you through flashing with a supported OBD tool. Mail-in: you ship us your ECU, we bench-flash it and return it with tracking. Most files are written within 24–72 hours.
How do I pay?
After you send your order through the contact form, we send an invoice with international payment options. Online checkout is coming soon.
Is afterfire safe for my catalytic converters?
We calibrate intensity and activation RPM precisely to limit the thermal stress that crude maps cause. It’s our signature product and the core of our engineering.
Can I go back to stock?
Yes. Your factory file is saved before any change and can be fully restored — for service, resale or any reason.
Will this void my warranty? Is it road legal?
All tunes are sold for off-road and motorsport use only and may affect your factory warranty and local emissions compliance. Regulations vary by country and state — please check your local rules.
Not sure which stage or method fits?
Talk to the engineer who’ll actually write your file. Remote service available worldwide.
All products are for off-road / motorsport use only. Modifications may affect factory warranty and emissions compliance — check your local regulations. Prices in USD, taxes and shipping excluded.
