CSG Ecutek Tuning Service for Toyota GR Supra 3.0 A90, G29 BMW Z4 m40i, BMW B58TU

CSG Spec tuning offers custom tuning application specific to the vehicle requirements through EcuTek tuning suite. Custom tunes are specific to VINs and cannot be shared to another other platform allowing for a truly customized experience for you. This customized tuning service is specific for your vehicle.

Which Tuning Level Do I Need?

Choose the level based on your existing modifications and/or goals:

For power goals above 550whp, especially on an upgraded turbo, it is required to run an upgraded fuel system. The proper path to do this is through Visconti's Stage 1 Fuel System and Motiv | Reflex Port Injection Kit, both of which CSG offers.

What does CSG's custom tuning service offer?

In our experience and extensive database of data acquired through thousands of hours of track testing and dyno R&D, "canned" tunes or "base" maps are never an "one-size fits all". Immediate gratification can be experienced quick base maps, but bespoke tunes specific to each modification list and individual vehicle is important to optimize and maintain consistency.

Through extensive test parameters, we are able to develop maps that provide smoother power delivery, better modulation, improved drivability, stable power improvements, and better consistency under stress. No one wants a one-pull wonder, but everybody wants something that's repeatable and useful, especially on the racetrack.

What ECUTEK hardware or licenses do I need?

See our EcuTek tuning guide .

Why do we always talk about track testing and R&D?

Track testing can be the most strenuous type of testing available. Since a major portion of our clientele is catered towards track driving and sprint/endurance racing, power delivery is required to be consistent and stable lap after lap regardless of how heat soaked and how hot or cold the ambient temperatures are. This development transfers over to daily and street applications.

Whether you're doing the Texas Mile pull or accelerating onto the freeway, you can expect power delivery to be predictable and consistent pull after pull. This is our goal and our way of doing things.
