The Bosch Motorsport MS 6.3 EVO is the first step into combined low-pressure and high-pressure injection control within the MS 6 EVO range. It manages gasoline engines up to 12 cylinders with port fuel injection as standard, and adds high-pressure direct injection capability via the optional HP package — making it suitable for GDI, DISI, and combined LP/HP stratified-charge engine strategies.
The HP package supports dual-bank high-pressure injection, enabling the MS 6.3 EVO to handle V-engines and flat-engines with two separate high-pressure fuel rails. This is the same HP hardware architecture as the MS 6.4 EVO — the key difference is that the MS 6.3 provides 21 analog inputs versus 38 on the 6.4. For engine installations with moderate sensor complexity where GDI is required, the MS 6.3 is the appropriate choice. For high sensor-count installations requiring GDI, step up to the MS 6.4 EVO.
Calibration uses RaceCon. Data analysis uses WinDarab V7. Custom algorithm development is available via the Customer Code Area and MATLAB/Simulink. All MS 6 EVO software upgrades — including FULL_LOG_1, USB Data, and gear control packages — are compatible.

FAQ
What is the HP package for the MS 6.3 EVO?
The HP (high pressure) package activates the direct injection output stages in the MS 6.3 EVO, enabling control of high-pressure GDI injectors alongside the standard port injection channels. It also enables the dual-bank option for V-engines and flat-engines with two separate HP fuel rails. The HP package is ordered as a software/hardware option at time of purchase.
Does the MS 6.3 EVO need the Bosch HPI5 for GDI control?
For most GDI applications, yes. Most motorsport GDI injectors require high-voltage solenoid drive current that the ECU output stages alone cannot deliver at the required peak current levels. The Bosch Motorsport HPI5 injection power stage provides the high-voltage drive for up to 5 GDI injectors and connects to the ECU via CAN.
What is the difference between the MS 6.3 EVO and MS 6.4 EVO?
Both support LP + HP injection and share the same chassis and software platform. The MS 6.3 EVO provides 21 analog inputs; the MS 6.4 EVO provides 38. If your engine installation requires more than 21 analog channels — additional pressure sensors, EGT channels, position sensors — choose the MS 6.4 EVO.
Is the MS 6.3 EVO compatible with MS 6.4 EVO RaceCon software?
Yes. The MS 6.1, 6.2, 6.3, and 6.4 EVO all share the standard MS 6 EVO software platform in RaceCon. Project files can be migrated between them. The only variant with its own separate software version is the MS 6.4P EVO.
What connector kit does the MS 6.3 EVO use?
The MS 6.3 EVO uses two Bosch proprietary connectors — a 91-pin and a 105-pin — totalling 196 pins. Bosch Motorsport offers mating connector kits (F02U.B00.711-01 and F02U.B00.712-01) that include housings, terminals, and seals for harness construction.
