MK7/MK7.5 Golf/Jetta/GTI/Golf R ECU Calibration

Fits: Volkswagen Golf, GTI, Golf R, Jetta and GLI, MK7 and MK7.5; 1.4TSI, 1.8T, 2.0T and 2.0T (R) engines.

What this is

A custom ECU calibration for the MK7 and MK7.5 Volkswagen Golf, GTI, Golf R, Jetta and GLI, developed in-house in Toronto by N75 Motorsports with WinOLS from the full factory definition (damos), so every map is defined. Delivered as a file (nothing ships) and built per order for your generation, engine and stage.

Pops and flames in Sport mode are available on request. We also tune the DSG transmission control unit (TCU) on these cars; it is not one of the options on this page, so email us if you want it.

Tune options

Choose MK7 or MK7.5, your engine and a stage. The mods each stage needs are not listed here, so email us your mods and fuel before you order and we confirm your stage.

Options explained

• Vehicle: MK7 or MK7.5, the generation of your car.
• Engine: 1.4TSI, 1.8T, 2.0T or 2.0T (R), the Golf R engine.
• Stage: 1, 2 or 3 on every engine; mods per stage are confirmed by email.
• Sport-mode pops and flames: on request; say so when you order.
• Other custom features: on request; email us with what you want.

How it works after you order

1. Email info@n75motorsports.ca before buying with your car (model, MK7 or MK7.5, engine, transmission), mods, fuel and how it will be flashed.
2. Order the Vehicle, Engine and Stage that match your car.
3. We build the calibration and deliver it as a file; nothing ships, so you need a way to flash it. If you have no flash tool, email us first: our OBD cellphone flash tool (compatibility is per vehicle) and our handheld tuner kit both include N75 tuning, so one of them may replace this listing for your car.
4. The file changes calibration data only, and the car can be flashed back to stock with the same tool.

How we tune

We tune from the full engineering files (damos) for these ECUs in WinOLS, so every map is defined. Our first Sport-mode pop map on a Golf R worked on the first attempt.

A VW Golf ECU file open in WinOLS: the map list is named from the full factory definition (damos).

FAQ

Do I send you my ECU?

This listing is the calibration file; nothing ships. Email us before ordering and we confirm how your car gets flashed.

Can I get pops and flames?

Yes, in Sport mode, on request; ask when you order.

Which stage should I choose?

Stage 1, 2 or 3 on every engine; email us your mods and fuel and we confirm the stage.

Use and liability notice

A tuned calibration needs the supporting mods and fuel we confirm with you by email before you order. N75 Motorsports takes no responsibility for damage where they are missing, the fuel is wrong, or a pre-existing fault worsens on a tune.
