❓ Frequently Asked Questions
Q: Will this void my warranty?
A: ECU tuning can void your powertrain warranty. We keep your stock tune on file if you need to reflash (additional fee applies). Consider the cloned ECU option to keep your OEM ECU untouched.
Q: What fuel should I use?
A: Choose 91 or 93 octane based on what's available in your area. 93 octane is recommended for maximum power gains. You must use the octane you're tuned for - never use lower octane.
Q: Will this work with my exhaust/intake mods?
A: Yes! This tune works great with bolt-on modifications like intakes, exhausts, and headers. The more mods you have, the better the gains.
Q: What if I add more mods later?
A: Let us know BEFORE ordering if you plan modifications. Changes after tuning may require a retune for optimal results.
Q: How does the cloned ECU option work?
A: You send us your OEM ECU, we clone it to a separate unit, tune the clone, and send both back. You keep your OEM ECU stock and swap to the tuned clone.
Q: How long does shipping take?
A: Tuning typically takes 3-5 business days after we receive your ECU, plus shipping time each way.
Q: Will my fuel economy change?
A: Fuel economy may improve slightly during normal driving due to better efficiency, but will decrease if you use the extra power frequently.
Refund Policy
No refunds on tunes for any reason once you have been sent a tuned ECU. You may request a refund at any time before that. Shipping costs will not be refunded.
⚠️ Disclaimer & Risks
Tuning your ECU requires specialty equipment and processes that may result in a bricked ECU. We take every precaution necessary to prevent this, but the risks are still there. In the event of a bricked ECU, you may need to purchase a replacement ECU or send your ECU off to get repaired which will incur additional time and cost.
Changing your factory tuning parameters can be dangerous and can result in damage to the engine and/or other parts of your drive train. We work with experienced tuners to avoid these types of problems, but there is still the risk of engine damage caused by improper installation of parts, incorrect information provided to the tuner about your mods and changing your mods after the tuning process. If you plan to make changes after your tune, let us know BEFORE you get tuned!
Changing your factory tuning parameters can result in your warranty being voided by the dealer and/or 3rd party insurers. We keep your original factory tune on file in the event you need to reflash back to stock, but this will incur an additional shipping and flash fee.
Legal Waiver
By placing your order, you are acknowledging that you accept all risks and agree that neither Blood Type Racing Inc, nor the tuner are liable or responsible for any damage for failures that may result from the tuning process, or the tune itself. This includes, but is not limited to, engine damage, bricked ECUs and any additional costs involved in the process (e.g. new ECUs or ECU repair, replacement of damaged parts, loss of warranty).
