Fits: Toyota GR Corolla. The GR Yaris and GR Corolla use the same ECU.
What this is
A calibration for the Toyota GR Corolla ECU, built by N75 Motorsports in WinOLS and written to your own ECU. You ship the ECU to us and we ship it back.
Through our worldwide tuner network we have already tuned the GR Yaris to 310 whp and over 330 wtq. The GR Yaris and GR Corolla use the same ECU, so we now offer the GR Corolla calibration in three stages.
Tune options
| Option | Target and output | Required mods and fuel |
|---|---|---|
| Stage 1 | Confirmed for your build by email before you order. | Confirmed from your mod list and fuel by email. |
| Stage 2 | Confirmed for your build by email before you order. | Confirmed from your mod list and fuel by email. |
| Stage 3 | Confirmed for your build by email before you order. | Confirmed from your mod list and fuel by email. |
Which stage fits depends on the hardware on the car and the fuel it runs. We confirm the stage from your mod list and fuel (see "How it works after you order").

How we tune
Autotuner reads and writes the ECU on our bench; WinOLS is where the calibration is built. The GR Corolla calibration is built on the GR Yaris work done through our network, because the two cars share the same ECU.
Before you order
- Email first (step 1 above) so we can confirm your car and the stage that matches its hardware and fuel.
- The car is off the road while the ECU is with us, so plan for the downtime.
- Shipping questions go to shipping@n75motorsports.ca.
FAQ
Do I send you my ECU?
Yes. This is a send-in calibration: you ship your ECU to us and we ship it back.
Is this the same work as the GR Yaris?
The GR Yaris and GR Corolla use the same ECU. The GR Yaris was tuned to 310 whp and over 330 wtq through our network; your ECU is written with the stage we confirm for your build.
Which stage should I order?
Email us with your mods and fuel before you order (step 1 above) and we confirm the stage.
Do you sell GR Corolla parts?
Yes, see our GR Corolla parts collection.
Use and liability notice
Higher stages need the supporting mods, fuel and plugs we confirm for your build. N75 Motorsports takes no responsibility for damage where they are missing, fuel or plugs are wrong, or a pre-existing fault worsens on a tune.
