FAQ
Service & Process
How does your mail-in ECU flashing service work?
Place your order online, remove your ECU, and ship it to us. Once received, we flash it with your selected options and send it back.
How do I send in my ECU?
After placing your order, package your ECU securely and ship it to us. The shipping address is provided at checkout and is also available on our Contact page. Be sure to include a paper with your order number and any tuning preferences inside the box.
When should I ship my ECU?
You should ship your ECU as soon as you’ve completed your order and received your confirmation email. We have no pre-shipment approval process. Make sure you have included your order number inside your package before sending it in.
Is the ECU flash reversible?
Yes, we can restore your ECU to factory settings. If you're not satisfied, this is included for free under our Flat Out Guarantee. Otherwise, it can be done later as a reflash.
How long does it take?
Once we receive your ECU, the turnaround time is typically 1–2 business days before it ships back out.
Can I use a second ECU for flashing and keep my original?
Yes, you can send in a spare ECU to be flashed while keeping your original untouched. Just make sure the spare is compatible with your bike. We recommend using the EXACT same part number as your stock ECU. Otherwise you may be left with a permanent check engine light.

What shipping options are available for returning my ECU?
We offer tracked international return shipping using NZ Post by default. If you need faster delivery or a specific carrier, contact us before placing your order to arrange an alternative.
Do you provide tracking for return shipping?
Yes, all return shipments include tracking. You’ll receive a tracking number by email once your ECU has been shipped back to you.
Can you flash my ECU if I am not located in New Zealand?
Yes, we accept ECUs from customers worldwide. As long as you're able to ship your ECU to New Zealand, we can flash it and return it to you.
How do I ship my ECU to New Zealand?
After placing your order, securely package your ECU and ship it to the address provided at checkout or on our Contact page. Be sure to include a note with your order number and tuning preferences. We recommend marking the package as "Used motorcycle part for service/repair and to be returned to sender." to help avoid customs delays. Feel free to use your preferred mailing service.
Do I need to pay customs fees when shipping to New Zealand?
In most cases, no. If you declare the ECU as a “used motorcycle part for service/repair and to be returned to sender” with a low value ($10–20 USD), it typically avoids duties and GST. However, customs policies vary by country, and any fees incurred are the sender’s responsibility.

FAQ
Tuning & Performance
What adjustments are made in the ECU?
We adjust parameters like fueling, ignition timing, throttle response, fan temps, rev limits, and speed or gear-based restrictions. All changes are tailored to your bike’s setup and riding goals. For specific changes or questions on adjustments, contact us directly.
What mods affect the tune?
Common mods that influence ECU tuning include full exhaust systems, slip-ons, air filters, velocity stacks, PAIR valve removal, intake changes, fuel type, and gearing. Be sure to list any relevant modifications when placing your order.
What is a burble and pop tune?
A burble and pop tune adjusts fuel and ignition timing during deceleration to create crackling or popping sounds. It’s a sound-only modification and doesn’t impact performance.
Can a burble and pop tune damage the engine or exhaust?
When done properly, no. Burble tunes work by igniting excess fuel in the exhaust during deceleration. This creates sound, not power. Unlike lean backfires that burn oxygen and can overheat components, this process burns cooler and is generally safe for healthy systems. However, aggressive settings or repeated abuse can shorten the life of exhaust components over time.
Will the ECU flash affect my quickshifter?
If your quickshifter is factory-installed, the flash will retain full compatibility. For aftermarket quickshifters, function typically remains unaffected, but some may benefit from fine-tuning if requested.
Will the flash smooth throttle jerks?
Yes, throttle response is one of the most noticeable improvements. The flash reduces on/off throttle jerkiness and creates smoother, more predictable power delivery. Especially at low speeds and during deceleration.
Can you tune for E85 or Race Fuel?
Yes, we can adjust fueling and ignition timing for E85 or most race fuels. Be sure to specify the exact fuel type you're using when placing your order, as each requires different tuning strategies.
Is the ECU flash emissions compliant?
No, our ECU flashes are intended for off-road or closed-course use only and may not comply with emissions regulations in your country. It is your responsibility to ensure compliance with local laws.
FAQ
General Concerns
How do I decide between a dyno tune and an ECU flash?
A dyno tune is ideal for highly customized builds and exact fuel mapping, but it requires time, access to a dyno, and a higher cost. An ECU flash is faster, more affordable, and provides significant gains with common mods. For most riders, a flash is the best all-around upgrade.
Does an ECU flash void my warranty?
An ECU flash may affect your manufacturer warranty, depending on your region and dealer. Some may deny coverage for engine-related issues. If warranty retention is important to you, check with your dealer before flashing.
Is an ECU flash safe for the engine?
Yes, when done properly, an ECU flash is safe and can even be healthier for your engine. We use conservative, tested settings that improve performance without compromising reliability. We do not push unsafe limits.
Do I need to list every single mod before flashing?
You don’t need to list every detail, but the more info you provide, the better we can tailor your flash. Key mods like exhaust, intake, fuel type, or quickshifter setup should always be included.
What happens if I change parts after the flash?
If you change key components like the exhaust, intake, or fueling setup after your flash, we recommend a reflash to ensure optimal performance. Discounted reflashes are available for returning customers.
What liability am I accepting by proceeding?
By using this service, you acknowledge that ECU flashing alters factory settings and may affect emissions compliance, warranty status, or mechanical longevity if misused. You assume full responsibility for how the bike is operated after tuning.
What happens if I cancel or need a refund?
If your ECU hasn’t been flashed yet, you may request a refund. Once flashing has begun, all sales are final. Shipping costs are non-refundable. Please contact us as soon as possible if you need to make changes to your order.
