McLaren 675LT ECU Tune



*** Unlock the hidden power gains detained in your McLaren’s ECU with a Hydra Motor Works ECU Tune. ***

Maximize your 675LT’s horsepower, torque and drivability with a Hydra Motor Works ECU Tune. Our tune is designed to take your 675LT’s performance to the next level while maintaining OEM reliability. Tuning this vehicle requires bench flashing the ECU. Bench flashing is when the ECU needs to be physically shipped to Hydra Motor Works for the tune to be completed.

How it works:

Customer will remove ECU from vehicle, package and ship it directly to Hydra Motor Works along with a completed ECU Tuning Guide.

Once the ECU arrives at our facility, our tuner will flash the unit within 24-48 hours.

ECU’s located in the domestic U.S. will be shipped back overnight. International ECU’s will be shipped back via Express-International shipping.


Please make sure you review, complete and email in our ECU Tuning Guide. This guide is to help us provide you with the most optimized tune for your vehicle’s specifications and modifications.

Power gains may vary depending on other modifications done to the vehicle.

This is not a tangible product. Customers are expected to ship the ECU in for reprogramming.
