/// DV-001 Build Sheet
Technical Reference
A living build reference for DV-001, including installed parts, planned upgrades, tested components, supporting modifications, and lessons learned as the car develops. The goal is not to list parts for the sake of listing parts. The goal is to show how each upgrade fits into the larger system.
Power, fitment, cooling, appearance, tuning, and drivability all affect each other. This section tracks the parts that shape the car and the reason each one belongs.
This list will keep evolving as DV-001 changes. Some parts are installed, some are purchased and waiting for the right supporting work, and some are still under review. The point is not to chase every possible upgrade. The point is to build the car in the right order.
Engine calibration, forced induction, airflow, and exhaust components that define the power direction of DV-001.
Core engine calibration path for the current B58 setup. Used as part of the Stage 2 tuning direction and paired with supporting hardware rather than treated as a standalone power button.
Required unlock step for ECU tuning on the modern BMW platform. This is part of the tuning foundation before calibration work can happen.
Active Autowerke
High-flow catted downpipe used to support the Stage 2 setup while keeping the car more livable and emissions-conscious than a catless approach.
Changed the exhaust character significantly. Improved tone and flow, but also made resonance and drone more obvious, which became part of the exhaust refinement process.
Dinan
Valved exhaust setup used to balance tone, flow, and livability. Works with the downpipe and Z-pipe to give the car more presence without turning every drive into a volume contest.
Candeo
Used to manage exhaust valve behavior and give more control over tone and cabin experience.
Dinan
Part of the airflow path supporting the B58 setup. Adds intake presence and works with the broader intake, turbo inlet, and charge pipe direction.
Dinan
Supports improved airflow into the turbo and pairs with intake-side upgrades.
Supporting reliability and airflow upgrade. Important once boost, heat, and tuning become part of the build.
Pure Turbos
Future turbo upgrade direction for the higher-output phase of DV-001. Should be paired with the right cooling, fueling, tuning, and drivetrain strategy.
Wagner Motorsport
Major cooling and airflow upgrade. Intended to support repeatable performance, improved intake temperature control, and the next phase of B58 development.
MHD
Potential future fueling flexibility upgrade. Should be considered alongside tuning strategy, ethanol goals, fuel availability, and monitoring.
Basic but important supporting maintenance for tuned B58 operation. Ignition health matters before asking more from the car.
TCU calibration and drivetrain support upgrades that work alongside the engine tune.
XHP Flashtool
TCU calibration used to make the transmission behavior match the engine tune and torque delivery. Engine tuning and transmission tuning should work together, not feel like separate projects.
Drivetrain support upgrade intended to improve control and reduce unwanted movement as power and load increase.
Heat shielding, airflow management, and cooling components that support repeatable performance.
Black Market Race
Added for heat management around the turbo area. Also helped reduce harshness and drone in the cabin, proving that heat and NVH can be connected in unexpected ways.
Supporting airflow and cooling detail. Part of keeping the engine bay and intake path more controlled.
Black Market Race
Visual and functional engine bay detail. Adds a more finished look to the engine bay.
Wagner Motorsport
Also belongs in this section because it is a major cooling-focused upgrade, not just an intake part.
Coilovers, wheel fitment, spacers, and alignment work that define how DV-001 sits and handles.
Bilstein
Major suspension upgrade used to control ride height, stance, and handling. Setup required refinement because lower is easy, but correct is hard.
Used to refine wheel position and fitment. Works with the wider wheel setup and lowered stance to create a more intentional look.
Part of the visual and fitment direction of DV-001. The car uses a staggered 19-inch setup with a strong OEM-plus stance.
Required after suspension and ride height changes. Alignment is what turns a lowered car from something that only looks good into something that actually drives correctly.
Brake system upgrades planned to support the added power and driving demands of DV-001.
Planned braking upgrade to support the added power and weight of the car while improving confidence during harder use.
Planned rotor upgrade to pair with pads and support the higher-performance direction of the build.
Appearance, aero, and exterior detail work that defines the visual direction of DV-001.
Major appearance and aero direction item. Fitment, paint preparation, sensor holes, carbon quality, and finish matter heavily here.
Carbon rear diffuser that helps define the rear of the car. This is one of the parts where quality and fitment matter because it changes the entire rear view.
Visual balance upgrade that helps connect the lowered stance, wheels, and aero direction.
Subtle rear aero and appearance upgrade. Adds shape without making the car feel overdone.
Appearance upgrade that changes the face of the car. Grille surrounds and fitment matter because the front of the G26 is already visually dominant.
Paint match and integration detail. Small pieces like this decide whether the car looks cohesive or pieced together.
Small appearance detail. Should be used carefully because small exterior pieces can either sharpen the car or make it look too busy.
Exterior carbon detail used to tie into the broader carbon theme.
Functional and visual detail. Helps protect lower panels while adding a motorsport-inspired appearance.
Small carbon accent. Works best when it complements the overall carbon direction without becoming cluttered.
Small badge detail used to darken the overall appearance.
BMW heritage detail. Adds a subtle special-edition look while still fitting the OEM-plus theme.
Gloss black roof wrap that changes the car's upper visual line and helps tie in the carbon and black exterior details.
Future appearance and comfort upgrade. Should support the darker exterior direction without making the car look overly blacked-out.
Cabin upgrades that improve the driving experience and tie the interior to the exterior build direction.
Pedal Haus
Interior tactile upgrade. Improves the performance feel inside the cabin.
BMW M Performance
OEM-plus interior detail that fits the BMW performance direction.
Interior carbon upgrade that ties the cabin to the exterior carbon theme. Quality matters heavily because interior parts are seen and touched every time the car is driven.
Interior comfort and support upgrade. Adds to the driving-focused cabin feel.
BMW M Performance
OEM-plus interior detail that makes the cabin feel more finished.
BMW M Performance
Tactile interior upgrade. Helps the control points feel more special.
Interior and driver-interface upgrade. The steering wheel is one of the most important touchpoints in the car.
Small detail upgrade. Not performance-related, but part of making the car feel more complete.
Battery, data logging, safety, and utility items that support the development and daily use of DV-001.
Optima
Battery upgrade supporting reliability and electrical stability.
Used as part of the monitoring and development setup. A clean permanent mount is better than a temporary install that feels unfinished.
Safety and utility item. Should be mounted cleanly and accessibly, with the driver-side location preferred. Relocation planned.
Changes pedal response and perceived sharpness. Useful for feel, but should not be confused with actual power tuning.
Engine bay dress hardware and structural details that support the finished technical look of DV-001.
Black Market Race
Engine bay dress-up detail that supports the finished technical look.
Black Market Race
Adds a more complete visual feel to the engine bay.
Dinan
Chassis and engine bay upgrade that adds structure and visual presence.
Part of the carbon engine bay direction. Works best when it supports the full build aesthetic rather than being random decoration.
Parts that are purchased and waiting, actively planned, or still under review for the next phase of DV-001 development.
