Base Maps
We have 91 AKI (95 RON) and 93 AKI (98 RON) base maps available for JDM cars. These maps are compatible with higher rated octane gasoline fuel and ethanol content up to E10.

- Turbocharger
- Air intake
- Fuel injectors
- Boost solenoid or different boost restrictor pill
- Headers, up-pipe, downpipe and some cat-back exhausts
- MAP sensor
- MAF sensor
- Ethanol content higher than E10

Users are advised to apply these base maps at their own risk and discretion. It is highly recommended that users consult with a professional tuner or mechanic to ensure that their vehicle's engine can safely accommodate the changes made by these base maps.
