Fits: Hyundai Genesis Coupe 2.0T and 3.8L; Hyundai Sonata Turbo (2.0T) and Kia Optima Turbo (2.0T) up to 2015.
What this is
An ECU calibration file for the Hyundai Genesis Coupe 2.0T and 3.8L, Hyundai Sonata Turbo and Kia Optima Turbo, developed in Canada by N75 Motorsports. File only: the flash tool for these cars is bought separately or added to your order.
The full factory definition (damos) for these ECUs lets us see and change every map, allowing very advanced tuning. Each file is built from an OEM calibration: your own ECU's read, or a matching OEM file from our database. Owners report that we helped them through the order, and a repeat customer reports their 3.8L came alive on the tune.
Tune options
| Stage | What it is | Required mods |
|---|---|---|
| Stage 1 | General retune of the OEM calibration. | Intake. |
| Stage 2 | Custom retune per your mods. | Colder spark plugs; FMIC upgrade (2.0T only); exhaust system. |
| Hybrid/Big Turbo Tune | Fully custom tune for your bigger-turbo setup, done with the car at our shop in Toronto, not remotely. | A bigger-turbo setup; email us before ordering. |
Choose Stage 1 for a car with an intake; Stage 2 once it has colder plugs, an exhaust system and, on the 2.0T, an FMIC upgrade; the Hybrid/Big Turbo Tune only with the car at our shop.
Options explained
- Motor (2.0T / 3.8L): pick the engine in your car. The FMIC requirement applies to the turbocharged 2.0T only; the 3.8L is naturally aspirated.
- Pops and bangs, or pops and flames: on request on the Genesis Coupe; a catless exhaust is required.
- No OEM file: we tune a matching file from our OEM-file database; email us first.
How it works after you order
- Email info@n75motorsports.ca before buying with your car, year, engine, transmission and mod list.
- Order the Stage and Motor.
- Read the ECU with the flash tool for these cars and send us the OEM file, or tell us you have none and we work from our database. EK1 device owners with a listed car (Genesis Coupe 2.0T, Genesis Coupe 3.8L or Kia Optima Turbo) order through our EK1 custom file listing instead.
- We tune your file and send it back.
- You write the tuned file with the same tool.
Calibration features
Developed in Canada with WinOLS; click the badge to verify our licence with EVC.
- Full factory definition: every map in the ECU is visible to us for advanced tuning.
- Full read and write: our tuning hardware and software read and write the ECU.
- Tuned from an OEM calibration: your own ECU's read, or a matching OEM file from our database, not a pre-tuned file.
Before you order
- File only; a flash tool is needed, bought separately or added to your order.
- A tune does not fix a mechanical problem. If the car does not run properly on the OEM calibration, it has a mechanical issue that needs fixing first, unless your build is extreme (for example a bigger-turbo setup, which we tune only with the car at our shop). These cars are now ten years old or more, so have the car looked over before tuning.
- Pops and bangs or pops and flames need a catless exhaust.
- Bigger-turbo setups are tuned with the car at our shop in Toronto; email us before ordering the Hybrid/Big Turbo Tune.
- The file changes calibration data only, and the car can be flashed back to stock with the same tool.
FAQ
Do I send you my ECU?
No. Read your ECU with the flash tool for these cars, send us the file and write the tuned file back yourself. EK1 owners with a listed car use our EK1 custom file listing.
I do not have my OEM file. Can you still tune my car?
Yes, from our OEM-file database. Email us first.
Can I get pops and bangs or flames?
Yes, on request for the Genesis Coupe; a catless exhaust is required.
Will you tune my bigger-turbo build remotely?
No. The car comes to our shop in Toronto; we cannot monitor the engine or verify the setup from a mod list remotely. These engines are at least ten years old, and unless fully rebuilt we need the car in front of us to tune it safely.
Use and liability notice
Every stage needs the listed supporting mods. N75 Motorsports takes no responsibility for damage where they are missing, plugs are wrong, the stock catalytic converters are kept on a pop tune, or a pre-existing fault worsens on a tune.
