The Infiniti G37 is a popular choice among car enthusiasts, known for its sleek design and impressive performance. One of the most effective ways to enhance its power and driving experience is through a custom ECU (Engine Control Unit) tune. In this article, we will explore real owner experiences with custom ECU tuning on the Infiniti G37, focusing on a case where a gain of 60 horsepower was achieved for an investment of $900.
Understanding ECU Tuning
ECU tuning involves modifying the software that controls the engine’s performance. By adjusting parameters such as fuel maps, ignition timing, and boost levels, tuners can optimize the engine’s output. This process not only increases horsepower but can also improve throttle response and overall drivability.
Owner Experience: The Journey to 60 HP
One Infiniti G37 owner decided to invest in a custom ECU tune after feeling that the car could deliver more power. Here’s a breakdown of their experience:
- Initial Thoughts: The owner felt that the G37 was quick but lacked the punch needed for spirited driving.

- Selection: The owner chose a reputable tuning shop known for their expertise with Infiniti vehicles.
- Cost: The total cost of the custom tune was $900, which included the tuning session and any necessary adjustments.
The Tuning Process
The tuning process began with a thorough diagnostic check of the vehicle to ensure that everything was functioning optimally. Once confirmed, the tuner connected to the G37’s ECU to extract the current settings.
After analyzing the data, the tuner made adjustments to the fuel maps and ignition timing. The owner was present during the process, allowing them to ask questions and understand the changes being made.
Results: The Power Gains
Upon completing the tuning session, the owner was eager to test the results. The dyno test revealed an impressive increase of 60 horsepower over the stock configuration. Here are some key outcomes:
