You acknowledge that performance, tuning, and ECU-related products and services involve inherent technical risk, including the risk of component failure, loss of vehicle drivability, and total component loss, and you accept that risk as a condition of purchase. 10. DME / ECU Unlock Services. THE FOLLOWING TERMS APPLY TO ANY DME UNLOCK, ECU UNLOCK, BENCH UNLOCK, OR SIMILAR SERVICE OFFERED BY THE COMPANY (COLLECTIVELY, "UNLOCK SERVICES"). BY PURCHASING AN UNLOCK SERVICE, YOU EXPRESSLY ACKNOWLEDGE AND AGREE TO EACH OF THE PROVISIONS BELOW. (a) Scope of the Unlock. An Unlock Service unlocks the bootloader of the DME (Digital Motor Electronics) or ECU so that the unit can be flash-tuned by you or a third party using compatible tuning software. THE UNLOCK SERVICE DOES NOT MODIFY, OVERWRITE, ALTER, OR OTHERWISE CHANGE THE CALIBRATION, MAPS, PARAMETERS, OPERATING SOFTWARE, OR VEHICLE-SPECIFIC DATA STORED ON THE DME. THE UNLOCK SERVICE IS A SOFTWARE PERMISSION CHANGE ONLY. (b) Pre-Existing Condition of the DME. The Company performs Unlock Services on the DME in the condition received. The Company does not, and cannot, audit, validate, or repair the existing software, calibration, or hardware integrity of a DME prior to performing an Unlock Service. If a DME has been previously flashed, partially flashed, interrupted during a flash, corrupted, modified, tampered with, water-damaged, electrically damaged, or otherwise compromised before being sent to the Company, the Unlock Service may still complete successfully on the bootloader while the underlying calibration or operating files remain corrupted or non-functional. THE COMPANY IS NOT RESPONSIBLE FOR THE CONDITION OR FUNCTIONALITY OF A DME THAT WAS ALREADY DAMAGED, FLASHED, BRICKED, OR CORRUPTED BEFORE THE UNLOCK SERVICE WAS PERFORMED. We have the right to refuse service to any DME that has obvious signs of being modified or compromised. (c) Removal, Shipping, and Reinstallation. You are solely responsible for safely removing the DME from your vehicle, packaging it, shipping it, receiving it back, and properly reinstalling it. The Company is not responsible for damage caused by improper removal, shipping damage, mis-seated or swapped connectors, bent or broken pins, electrostatic discharge, water or contamination exposure, or any other handling-related issue occurring outside the Company's physical possession of the unit. (d) Required Use of Compatible Tuning Software. An unlocked DME still requires properly licensed, vehicle-appropriate tuning software (such as bootmod3, MHD, or other compatible platforms) to flash a tune. The Company does not provide such licenses as part of the Unlock Service unless explicitly stated in writing on the order. You are responsible for selecting, purchasing, and correctly using the appropriate tuning software, and for verifying compatibility with your specific vehicle and DME hardware/software version. (e) No Guarantee of Vehicle Operation Post-Service. While the Company performs Unlock Services using industry-standard tooling and processes, the Company does not guarantee that your vehicle will operate without fault, warning lights, limp mode, or diagnostic trouble codes following reinstallation, particularly where pre-existing conditions, third-party modifications, sensor failures, wiring issues, or installation errors are present. (f) Sole Remedy for Unlock Services. Notwithstanding any other provision of these Terms, your sole and exclusive remedy for any claim arising out of or relating to an Unlock Service shall be, at the Company's sole election: (i) a refund of the amount paid for the Unlock Service; or (ii) a re-attempt of the Unlock Service on the same unit. THE COMPANY SHALL NOT BE LIABLE FOR THE COST OF DME REPLACEMENT, DEALER DIAGNOSTIC FEES, TOWING, RENTAL VEHICLES, LOSS OF USE, LOST WAGES, OR ANY OTHER DIRECT, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES. (g) Acknowledgment of Risk. UNLOCK SERVICES INVOLVE INHERENT TECHNICAL RISK. BY PURCHASING AN UNLOCK SERVICE, YOU REPRESENT THAT YOU HAVE INDEPENDENTLY RESEARCHED THE PROCEDURE, UNDERSTAND ITS PURPOSE AND LIMITATIONS, AND ACCEPT FULL RESPONSIBILITY FOR THE OUTCOME ON YOUR VEHICLE. (h) Age and Authority to Purchase. Unlock Services and other tuning-related services are offered only to purchasers who are at least eighteen (18) years of age and who are the legal owner of the vehicle (or an authorized agent of the owner). By purchasing an Unlock Service, you represent and warrant that you meet these requirements. The Company reserves the right to cancel any order found to be in violation of this provision and to refund the amounts paid, less any costs already incurred. 11. Goods Not for Resale or Export. You represent and warrant that you are buying products or services from the Site for your own use only, and not for resale or export. You further represent and warrant that all purchases are intended for final delivery to the location you identified in your order at the Site. 12. Limitation of Liability. (a) IN NO EVENT SHALL WE BE LIABLE TO YOU OR ANY THIRD PARTY FOR CONSEQUENTIAL, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR ENHANCED DAMAGES, LOST PROFITS OR REVENUES OR DIMINUTION IN VALUE, ARISING OUT OF, OR RELATING TO, AND/OR IN CONNECTION WITH ANY BREACH OF THESE TERMS, REGARDLESS OF (i) WHETHER SUCH DAMAGES WERE FORESEEABLE, (ii) WHETHER OR NOT WE WERE ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, AND (iii) THE LEGAL OR EQUITABLE THEORY (CONTRACT, TORT OR OTHERWISE) UPON WHICH THE CLAIM IS BASED. (b) OUR SOLE AND ENTIRE MAXIMUM LIABILITY, FOR ANY REASON, AND YOUR SOLE AND EXCLUSIVE REMEDY FOR ANY CAUSE WHATSOEVER, SHALL BE LIMITED TO THE ACTUAL AMOUNT PAID BY YOU FOR THE PRODUCTS AND SERVICES YOU HAVE ORDERED THROUGH OUR SITE. (c) The limitations of liability set forth in this Section 12 shall (i) only apply to the extent permitted by law, and (ii) not apply to any liability resulting from our gross negligence or willful misconduct. 13. Force Majeure. We will not be liable or responsible to you, nor be deemed to have defaulted or breached these Terms, for any failure or delay in our performance under these Terms when and to the extent such failure or delay is caused by or results from acts or circumstances beyond our reasonable control, including, without limitation, acts of God, flood, fire, earthquake, explosion, governmental actions, war, invasion or hostilities (whether war is declared or not), terrorist threats or acts, riot or other civil unrest, national emergency, revolution, insurrection, epidemic, pandemic, lockouts, strikes or other labor disputes (whether or not relating to our workforce), restraints or delays affecting carriers, inability or delay in obtaining supplies of adequate or suitable materials, or telecommunication breakdown or power outage. 14. Governing Law and Jurisdiction. All matters arising out of or relating to these Terms are governed by and construed in accordance with the internal laws of the State of New Jersey without giving effect to any choice or conflict of law provision or rule (whether of the State of New Jersey or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than those of the State of New Jersey. 15. Dispute Resolution and Binding Arbitration. YOU AND THE COMPANY ARE AGREEING TO GIVE UP ANY RIGHTS TO LITIGATE CLAIMS IN A COURT OR BEFORE A JURY, OR TO PARTICIPATE IN A CLASS ACTION OR REPRESENTATIVE ACTION WITH RESPECT TO A CLAIM. OTHER RIGHTS THAT YOU WOULD HAVE IF YOU WENT TO COURT MAY ALSO BE UNAVAILABLE OR MAY BE LIMITED IN ARBITRATION. ANY CLAIM, DISPUTE OR CONTROVERSY (WHETHER IN CONTRACT, TORT OR OTHERWISE, WHETHER PRE-EXISTING, PRESENT OR FUTURE, AND INCLUDING STATUTORY, CONSUMER PROTECTION, COMMON LAW, INTENTIONAL TORT, INJUNCTIVE AND EQUITABLE CLAIMS) BETWEEN YOU AND US ARISING FROM OR RELATING IN ANY WAY TO YOUR PURCHASE OF PRODUCTS OR SERVICES THROUGH THE SITE, WILL BE RESOLVED EXCLUSIVELY AND FINALLY BY BINDING ARBITRATION. The arbitration will be administered by the American Arbitration Association ("AAA") in accordance with the Consumer Arbitration Rules (the "AAA Rules") then in effect, except as modified by this Section 15. (The AAA Rules are available at www.adr.org/arb_med or by calling the AAA at 1-800-778-7879.) The Federal Arbitration Act will govern the interpretation and enforcement of this section. The arbitrator will have exclusive authority to resolve any dispute relating to arbitrability and/or enforceability of this arbitration provision, including any unconscionability challenge or any other challenge that the arbitration provision or the agreement is void, voidable, or otherwise invalid. The arbitrator will be empowered to grant whatever relief would be available in court under law or in equity. Any award of the arbitrator(s) will be final and binding on each of the parties, and may be entered as a judgment in any court of competent jurisdiction. You may elect to pursue your claim in small-claims court rather than arbitration if you provide us with written notice of your intention to do so within sixty (60) days of your purchase. The arbitration or small-claims court proceeding will be limited solely to your individual dispute or controversy. You agree to an arbitration on an individual basis. In any dispute, NEITHER YOU NOR THE COMPANY WILL BE ENTITLED TO JOIN OR CONSOLIDATE CLAIMS BY OR AGAINST OTHER CUSTOMERS IN COURT OR IN ARBITRATION OR OTHERWISE PARTICIPATE IN ANY CLAIM AS A CLASS REPRESENTATIVE, CLASS MEMBER, OR IN A PRIVATE ATTORNEY GENERAL CAPACITY. The arbitral tribunal may not consolidate more than one person's claims, and may not otherwise preside over any form of a representative or class proceeding. The arbitral tribunal has no power to consider the enforceability of this class arbitration waiver and any challenge to the class arbitration waiver may only be raised in a court of competent jurisdiction. If any provision of this arbitration agreement is found unenforceable, the unenforceable provision will be severed, and the remaining arbitration terms will be enforced. 16. Assignment. You will not assign any of your rights or delegate any of your obligations under these Terms without our prior written consent. Any purported assignment or delegation in violation of this Section 16 is null and void. No assignment or delegation relieves you of any of your obligations under these Terms. 17. No Waivers. The failure by us to enforce any right or provision of these Terms will not constitute a waiver of future enforcement of that right or provision. The waiver of any right or provision will be effective only if in writing and signed by a duly authorized representative of the Company. 18. No Third-Party Beneficiaries. These Terms do not and are not intended to confer any rights or remedies upon any person or entity other than you. 19. Notices. (a) To You. We may provide any notice to you under these Terms by: (i) sending a message to the email address you provide; or (ii) by posting to the Site. Notices sent by email will be effective when we send the email and notices we provide by posting will be effective upon posting. It is your responsibility to keep your email address current. (b) To Us. To give us notice under these Terms, you must contact us by either (i) using the "Contact Us" form provided at the Site, or (ii) contacting us by email at info@kiesmotorsports.com. We may update the method for notices to us by posting a notice on the Site. Notices provided by electronic transmission will be effective one business day after they are sent. 20. Severability. If any provision of these Terms is invalid, illegal, void or unenforceable, then that provision will be deemed severed from these Terms and will not affect the validity or enforceability of the remaining provisions of these Terms. 21. Entire Agreement. These Terms, together with any order confirmation or invoice we issue to you, will be deemed the final and integrated agreement between you and us on the matters contained in these Terms.
