Oakes Performance Solutions - 2nd Generation EA825 4.0T Engine ECU & TCU Software
Introducing Oakes Performance Solutions in association with Custom Code, offering 2nd generation EA825 4.0T engine ECU and TCU software for multiple Audi, Porsche, Bentley, and Lamborghini models. These tunes are based on the developmental 2019 Audi SQ8 and 2019 Lamborghini Urus.
ECU and TCU Tunes for 2nd Generation EA825 4.0T V8 Engines
The ECU tunes for these 2nd generation EA825 4.0T V8 engines come in three stages to accommodate our customer's needs. The TCU tune is required for the Stage 2 and Stage 3 ECU tunes due to increased stresses on the components, especially from the higher EGTs/Exhaust Gas Temperatures. It also helps modify or remove torque limitations for optimal performance.
Oakes Performance Solutions Commitment to Power and Performance
At Oakes Performance Solutions, we prioritize delivering power to the pavement. Therefore, we emphasize acceleration times as the most important metric. The horsepower and torque numbers are listed after the acceleration differences because there are multiple occasions where these gains cannot be accurately represented on a dyno. We want you to feel the difference immediately after downloading the tunes and driving out of your driveway! The listed range of acceleration differences and horsepower/torque gains accommodates the variations in engines and chassis.
Maintenance Recommendations for Best Performance
For optimal performance, we recommend performing regular maintenance servicing on these 2nd generation EA825 4.0T engines. This includes replacing the engine air and fuel filters, worn spark plugs, and fixing or replacing any clogged exhaust components, such as catalytic converters.
2019 Lamborghini Urus Case Study
Our 2019 Lamborghini Urus shop SUV, previously owned by Randy from Savage Garage, serves as a case study. Despite its low mileage, it underwent necessary maintenance servicing, including new spark plugs and a transmission fluid change, before tuning, due to the spirited driving it experienced in its prior ownership.
According to Dragy testing on 93 octane pump gas, here are the acceleration time differences for the 2019 Lamborghini Urus:
- Stock: 3.48 seconds 0-60 mph time with an 11.50 seconds 1/4 mile time at 120.04 mph.
- Stage 1 ECU tune: 3.14 seconds 0-60 mph time with an 11.02 seconds 1/4 mile time at 126.28 mph.
- Stage 2 ECU and TCU tune: 2.81 seconds 0-60 mph time with a 10.69 seconds 1/4 mile time at 131.43 mph.
Compatible 2nd Generation EA825 4.0T Vehicles in the USA
These tunes are compatible with the following 2nd generation EA825 4.0T vehicles in the USA:
- Audi: SQ7, RSQ7, SQ8, RSQ8, A8/A8L, S8, RS6, RS6 Performance, RS7, and RS7 Performance
- Porsche: Cayenne and all versions of the Panamera
- Bentley: Continental GT V8, Flying Spur, Bentayga

Tuning Cable Rental and Purchase Options
The ECU and TCU tunes are downloaded by you through the Custom Code online server that requires renting or purchasing one of our tuning cables. It costs $30 to rent a tuning cable after all the steps of the rental program are completed or $150 to purchase a tuning cable. The tuning cable rental program consists of a $150 core deposit plus shipping costs initially. Then after the tuning cable is shipped back in good condition within seven business days from initially arriving then $120 of the core deposit will be refunded. If there are any issues with downloading the tunes caused by Oakes Performance Solutions or Custom Code like a server update or file revision then that time delay will not be held against the customer.
