Tuning the Valtra N135

2022 Valtra N Series

N135  – 4.9L



Bosch EDC17CV41 ECU

The Challenge

This article is dedicated to explaining how tuning the Valtra N135 can be liberated from the constraints imposed by its factory settings. By adjusting the factory ECU settings using ECU tuning technology, the latent power hidden within the vehicle can be unleashed.

The 2022 Valtra N135 Direct, a member of the N series, is renowned as a front loader specialist. Featuring an integrated heavy-duty leader subframe and a lock-and-go loader attachment, its front loader capabilities extend beyond farm work to applications like municipality or airport maintenance, as well as forestry work. Powered by a 4.9L 4-cylinder 49 LFTN-D5 engine controlled by a Bosch EDC17CV41 ECU, the Bosch ECU is crucial in enabling the tractor to realize its full potential, enhancing efficiency in various tasks.

The Solution

ECU tuning, a technology dedicated to adjusting ECU settings for improved power and torque output, is the key solution. At Alt Tune, we specialize in customizing ECU settings to optimize power usage for your benefit. Through a custom tune from Alt Tune, your Valtra N135 can experience increased power and torque, resulting in higher ground speed, enhanced pulling and pushing capabilities, and ultimately, heightened productivity for your operations. We use the Alientech KESS3 to flash the custom tune into the Valtra N135’s Bosch ECU.

Reliability is paramount for any tractor, and issues with emission system settings can compromise this reliability. The Valtra N135 comes equipped with both DPF and Adblue (SCR/DEF), and problems with these emission systems can lead to significant expenses in terms of lost work and mechanical bills. To address this, we offer a solution that adjusts the ECU settings for the emissions system, neutralizing potential issues. With both a custom tune and Alt Tune’s emissions solution, your Valtra N135 can become more productive and reliable, minimizing disruptions and optimizing performance.

Further Benefits Of ECU Tuning The Valtra N135

Increased Power and Torque

With more power and torque, a tuned tractor can handle heavier loads and perform tasks more efficiently. It allows the tractor to pull or push larger implements, haul heavier loads, and complete tasks faster, resulting in increased productivity.

Years of Development

We have been tuning Valtra’s 4.9L diesel engine for years, and understand how they work as well as the limitation on factory hardware.


Easy and fast programming

Easy, fast and non-evasive via programming the factory-fitted diagnostic port.
