Terms of use

These terms of use are applicable to all eFlexFuel E85 conversion kits, their wiring harnesses, and their accessories manufactured by StepOne Tech Ltd (the manufacturer). Please read these terms of use carefully before using or attempting to install the eFlexFuel or the related components. This ensures that both parties (the buyer and the seller) are aware of how to proceed in different operational situations of the eFlexFuel.

Guarantee and refund

The manufacturer offers a one-year (12 months) manufacturer's guarantee to the control unit and to other components. The guarantee applies only to the conversion kit, the included wiring harness, ethanol sensor, and their functionality. Always read the instructions on this instruction manual in its entirety before attempting to install or use the eFlexFuel. This ensures that the product operates to its full potential.

The guarantee does not cover damages caused by improper installation by the buyer or by the buyer's agent, or if the product has been damaged by wear that is not caused by normal use or by a manufacturing defect.

The guarantee covers faulty installation by the manufacturer or by an authorized dealer. Any modification done to the conversion kit without the consent of the manufacturer voids the guarantee.

If the product has a fault that can be regarded as a result of a faster than normal wear or a result of a manufacturing defect, the manufacturer will provide the buyer with a new product or repair the faulty product within the time that is seen appropriate by the local consumer protection act. The manufacturer has the right to redeem the faulty product if it is replaced by a new one.

The manufacturer reserves the rights to any modifications, expansions, attachments, or improvements made by customer.

The manufacturer has to accept returns of unused products within 32 days as stipulated by the Chapter 6 of the Finnish consumer protection act.

Product liability

The use of eFlexFuel conversion kit happens at the user's own responsibility. Please take into account that a guarantee offered by a car manufacturer may be void once a conversion kit has been connected to the car's systems.

The manufacturer commits only to make up for damage caused to the conversion kit, the accompanied wiring harness, or accessories as covered by the guarantee.

The manufacturer does not make up for damage caused to the car by the use of ethanol containing fuel. Neither does the manufacturer make up for damage caused by the installation to the product, the installation's target or the person carrying out the installation, if the installation is carried out by the customer or by customer's agent.

Ethanol sensor should be connected with accessories (incl. quick connectors and fuel hose) approved by manufacturer.

Manufacturer is not responsible for consequences resulted from violating local regulations. User must be aware of local regulations regarding upgrading a vehicle for bioethanol based fuel. Please take into account that using eFlexFuel could be against the law in some parts of the world.
