Below You will find a list of Frequently asked questions regarding our service.

Can I do it myself?

Yes, you can! We design all our devices with simplicity in mind. Each product we provide is already configured for your machine. The plugs on our kit’s wiring harness are exactly the same as on your machine. It’s a true Plug & Play solution

Will it void the warranty?

No, the delete kit is an additional non-invasive device. It connects with your machine in a way that still allows you to take your machine to the shop for firmware updates. Even if you plug in a diagnostic computer, there’s no way to tell the device is installed, as it sends exactly the same signals as the original DPF or SCR/DEF system does.

Do I need to remove the filter?

With our delete kit, you can safely bid farewell to the inconveniences of the DPF filter. Removing it ensures your machine runs smoothly for years to come. Once our emulator is installed, your machine will continue to operate seamlessly, even without the DPF filter. Enjoy enhanced performance without the filter issues!

Do I still need to add DEF/AdBlue?

Absolutely not! With our technology, you’ll never need to worry about refilling DEF/AdBlue fluid again. Imagine your diesel engine being as reliable as it used to be, hassle-free and without the need for constant refills. Say goodbye to DEF/AdBlue fluid refills and hello to savings!

Will the error codes disappear?

Delete kit replaces the signals transmitted by faulty components. Instead of replacing a damaged part only for it to break down again, just replace it with its digital alternative. While erasing fault codes may be necessary in some cases, our specialists are here to help. Get in touch with us today, and let’s find the perfect solution for your machine together!

Will it still regenerate?

The regeneration process will be done digitally which means that instead of a typical long and fuel consuming regeneration process your machine will perform a regeneration virtually, without any physical symptoms, allowing you to keep working and not lose a second of your precious time.

Is it safe?

The device does not interfere with the engine’s functionality. It is completely safe and thanks to the use of original plugs fully non-invasive. After removing the DPF, you reduce the pressure in the exhaust system, making it easier for the engine to blow out the exhaust fumes, granting you a boost of power

What is the warranty?

We stand behind our products with a 24-month warranty included with every single device. Additionally, you’ll gain full access to our tech support channel. Our technicians are dedicated to ensuring your machine operates flawlessly.

What is the shipping time?

Once payment is processed, we ship the device next business days. Our standard transit time to most countries ranges from 2 to 5 business days, ensuring you receive your device promptly.

What is the cost?

Our pricing varies depending on factors such as engine specifications and emission type. To ensure you receive the best offer, we encourage you to contact our sales team. By doing so, we can provide you with a solution tailored for your engine.

What about the EGR?

Your engine relies on the precise proportion of air and fuel mixture in the combustion chamber to function optimally. Blocking or disabling the EGR (Exhaust Gas Recirculation) disrupts this proportion, potentially causing deterioration to your engine. Over time, this will result in your machine emitting white smoke and potentially burning holes in the engine walls. However, after removing the DPF filter, the EGR begins to serve its purpose effectively by recirculating hot gases back to the combustion chamber, contributing to improved engine performance and extra horsepower.

How do I know if it will fit my machine?

Rest assured, we specialize in our craft. As manufacturers of this solution, we can create a device configured specifically for your machine. With 15 years of experience under our belt, you can trust that we’ll make sure our device will fit your machine.

Is it durable?

Our devices are crafted from shock resistant, high-quality materials designed to withstand extreme conditions. They are waterproof, dustproof, and shockproof, ensuring long-lasting durability even in the harshest environments.

Do I need a computer?

No, you don’t need a computer. Our delete kit is a self-sufficient device that operates independently, eliminating the need for a computer.

Do I need to send in my ECU?

Absolutely not! Our method of removing emissions from your machine doesn’t involve disassembling any of the machine’s electronics. We don’t make any changes to the machine’s original programming.

What is the payment method?

Our primary payment method is PayPal, offering security and flexibility of paying with a credit or debit card. Alternatively, we also accept standard wire transfers for your convenience.

Is it reversible?

Yes, absolutely! Our solution is fully reversible. At any time, you can return to the original configuration by simply unhooking our device.

Can I pay extra for overnight shipping?

We understand the value of time and the importance of meeting your deadlines. Upon request, we can arrange shipping tailored to your needs, including overnight shipping options for expedited delivery. Your satisfaction is our priority.

Why should I do this?

Overcomplicated diesel aftertreatment systems can increase the likelihood of defects in your machine (lead to malfunctions and eventually fully ground of your machine). Deleting emission is a method of combining modern technology and the old design, ensuring reliability and efficiency. By simplifying the system, you can enjoy greater peace of mind and improved performance.

What are the additional benefits?

Eliminating the fuel-consuming regeneration process leads to improved fuel economy of your machine. Additionally, by reducing pressure in the exhaust system, you will experience a boost of power. Our solution not only simplifies operations but also enhances performance, ensuring a more efficient and powerful machine overall.

Why emulation and not reprogramming?

Emulation ensures optimal hardware performance by using original software. Reprogramming, on the other hand, fits your machine with a modified version of the original software. Imagine using a computer with a hacked operating system – it’s not ideal. Emulation maintains the integrity and reliability of your machine’s software, offering a more secure and effective solution without losing your warranty.

Is there a manual included?

Absolutely. Inside the box, you’ll find the device, wiring harness, and a comprehensive manual that guides you through the installation process step by step. Additionally, our technicians are available to assist you throughout the entire installation process, ensuring a smooth and hassle-free experience.

How can I order it?

Ordering is easy! Simply click the “Get a quote” button, and one of our sales representatives will promptly contact you. Or you can give us a call. It’s that simple!

What is the refund process like?

If you need a refund, just reach out to your handler and explain the situation. Once the technician verifies the operability of the device, your handler will initiate the refund or arrange a replacement device, ensuring your satisfaction.
