Take control of your Toyota’s performance with ease.



What is ECU Multi-Mapping?
Multi-mapping is an advanced upgrade available for selected Toyota diesel vehicles. Unlike standard ECU remapping, this service programs multiple custom maps directly into your vehicle’s ECU, allowing you to switch between different performance profiles without the need for reprogramming.
Our custom-designed 6-position switch is neatly integrated into your vehicle’s cabin and offers quick access to various map settings tailored to different driving conditions—such as towing, off-road performance, or general driving.

Frequently Asked Questions
How does multi-mapping differ from standard ECU remapping?
Standard ECU remapping provides one set of parameters, while multi-mapping stores multiple maps in your ECU that you can switch between using our custom rotary switch. This gives you versatility for different driving conditions without needing to reprogram your ECU.
Will multi-mapping affect my Toyota's reliability?
No, our multi-mapping upgrades are designed with reliability in mind. We carefully develop each map to enhance performance while maintaining safe operating parameters for your engine.
How long does the multi-mapping installation take?
Most installations take approximately 4-5 hours, depending on your specific Toyota model. We recommend booking in advance and allowing a full day for the service.
Can I switch between maps while driving?
Yes, most maps can be switched while driving (except the Immobiliser function, which only works when stationary). The transition between maps is smooth and doesn’t interrupt your driving experience.
Will multi-mapping void my vehicle warranty?
This depends on your specific warranty terms. We’re happy to discuss this in detail and can provide options that minimise any potential warranty implications.
Do you offer multi-mapping for other vehicle brands?
