How your tune happens

1. Order and confirm Add the tune to your cart or request a consultation. We confirm your exact year, engine and any hardware already on the car before anything is written.
2. Flash method Depending on the platform, the tune loads through the OBD port with a handheld flasher we ship to you, or the ECU is unlocked once on the bench at our Sugar Land shop. The brand notes below say which applies to your car.
3. Calibration Your file is built for your engine, fuel (91 or 93 octane) and hardware. Stage 2 files assume downpipes are installed; if yours are not, the downpipes for your car are listed on this page.
4. Datalog and revise After the first drive we review logs and adjust. Revisions during the break-in period are included.
5. Support Return to stock is always available. Questions before or after: email us and we will get back to you.

Most 2016 and newer BMWs (B48, B58, S55, S58, N63 and S63 engines) flash through the OBD port. Newer G-series cars with locked MG1 or MD1 ECUs need a one-time unlock on the bench at the shop, after which future updates go through the port. Stage 1 is software only on stock hardware. Stage 2 is calibrated for high-flow or catless downpipes and needs them installed. A transmission (TCU) tune is optional and adds faster shifts and raised torque limits on the ZF8 and DCT boxes.

Stage 2 is written for downpipes; the ones for your car are listed below
