Hyundai DCT-WET 8 Speed TAD801 TCU Tuning File - EK1 File available

Fits: Hyundai N cars with the 8-speed wet dual-clutch transmission and the TAD801 TCU: Veloster N DCT, Elantra N DCT, Kona N.

What this is

A TCU (transmission control unit) calibration file for the 8-speed wet dual-clutch transmission, developed in Toronto by N75 Motorsports with WinOLS on our own car, delivered as an EK1 file or by flashing your shipped-in TCU. It changes clutch clamping load, shift schedule, TCU torque request, RPM, forced downshift and, in beta, launch control.

An N75 Motorsports ECU tune on the car is required. This file was developed and tested on our own car; we cannot say how it will perform without an N75 ECU tune. See our Elantra N, Kona N and Veloster N ECU calibrations, on a spare ECU or as an EK1 file.

Tune options

Stage 1 is clamp load and shifting only; Stage 2 adds RPM, torque request and the beta launch feature.

Options explained

• Hyper Launch (Stage 2): launch control, in beta and still in development; the aim is a 60-foot time under 2.0 seconds, made available as it develops.
• Forced downshift: the downshift redline limiter is raised, so downshifts are allowed up to the ECU's 8,160 RPM maximum.
• Spare TCUs: we are also testing spare TCUs; email info@n75motorsports.ca if you want to take part.
• Ongoing development: new tools are revealing more maps; features we add after testing are made available to existing buyers.

How it works after you order

1. Email info@n75motorsports.ca before ordering with your car, transmission and which N75 ECU tune you run.
2. Order Stage 1 or Stage 2 and say in the order notes which route you want.
3. EK1 route: you need an EK1 device and a bench kit for the TAD801 TCU from EK1Tool.com; neither is included. We deliver the file through our tuning portal; email us for the read and write steps for your device.
4. Ship-in route: remove the TCU and ship it to us; we flash it and ship it back. Shipping questions: shipping@n75motorsports.ca.

Calibration features

Developed in Canada with WinOLS on our own car; click the badge to verify our licence with EVC.

• Increased RPM.
• Forced downshift: the downshift redline limiter is raised, so the transmission will rapidly downshift into any gear the driver requests, up to the ECU maximum of 8,160 RPM.
• Increased torque request from the TCU.
• Increased clamping load for the clutch.
• Hyundai TC shift mapping.
• Hyper Launch: in beta and still in development; the aim is a 60-foot time under 2.0 seconds.

How we tune

No definition file existed for this TCU, so we found the maps and tested every change on our own car, with aid from Hyundai Motor Company Canada and critical insight on the TCU from Hyundai Motorsport. Hundreds of hours of development went in before the first TCU was flashed. We find the maps, own the test cars and produce the file ourselves.

Before you order

• An N75 Motorsports ECU tune on the car is required; we cannot say how the file will perform without one.
• The EK1 device and the bench kit are not included; the bench kit for the TAD801 TCU is bought from EK1Tool.com.
• Hyper Launch is in beta.
• The file changes calibration data only.

FAQ

Do I need an N75 ECU tune as well?

Yes. We cannot say how the file will perform without one.

Do I have to send you my TCU?

Not if you have an EK1 device and a bench kit for the TAD801 TCU; otherwise ship it to us and we flash it and ship it back.

Will I get features you add later?

Yes, once we have tested them.

Use and liability notice

This TCU file requires an N75 Motorsports ECU tune on the car. N75 Motorsports takes no responsibility for damage or poor performance where the file is run without one, or where a pre-existing transmission or clutch fault worsens on a tune.
