Ultimate Infiniti and UpRev Tuning Guide

Ultimate Infiniti and UpRev Tune Guide

Since the early 2000s, Infiniti has introduced a range of luxury-performance vehicles to South Africa, many powered by Nissan’s legendary VQ-series V6 engines. These engines are not only smooth and reliable but also highly tunable. With UpRev ECU tuning, Infiniti owners can unlock hidden performance, sharper throttle response, and improved drivability without compromising everyday comfort.

UpRev supports a wide variety of Infiniti models sold or imported locally, including the G35, G37/Q60, FX35/FX37, M35/M37, and QX70 3.7. Each of these models shares the same strong tuning potential as their Nissan counterparts, making them ideal candidates for ECU remapping.

With the right combination of airflow upgrades, long-tube headers, high-flow exhaust systems, and a custom UpRev remap, these engines gain significant power across the rev range. Typical Stage 1 upgrades deliver an extra 15–30 kW at the crank, along with smoother power delivery and quicker acceleration.

Whether you drive an Infiniti G coupe for weekend performance or an FX/QX SUV for refined daily power, Race Breed Technology can fine-tune your Infiniti to deliver maximum safe performance on South African fuel. Our focus is always on reliability, drivability, and measurable gains backed by dyno testing.

How to confirm your exact car is supported

How to Confirm if Your Infiniti is Supported by UpRev

While most Infiniti models with the VQ-series V6 engines are supported by UpRev, the best way to be 100% certain is to check your ECU’s ROM ID. This tells us if your specific car’s ECU file is in the UpRev database and can be tuned.

Ways to Confirm Support:

ECU Read at Our Workshop

Bring your Infiniti to Race Breed Technology in Athlone, Cape Town.
We’ll connect to your ECU, read the ROM ID, and instantly confirm UpRev compatibility.
Provide VIN + ECU Part Number
If you can’t bring the car in right away, send us your Vehicle Identification Number (VIN) along with the ECU part number (found on the ECU label in the engine bay or footwell).
With this information, we can verify support with the UpRev database.
Direct Enquiry
If you’re unsure, simply contact us with your car’s model, year, and engine details (e.g., Infiniti G37 3.7 VQ37VHR, 2012).
We’ll let you know if your car is UpRev supported and recommend the best tuning options.
