The Bosch Motorsport MS 6.4 EVO is the top-specification unit in the 667 MHz MS 6 EVO hardware generation, combining the full 38-channel analog input count with complete GDI (direct injection) capability. It manages gasoline engines up to 12 cylinders on port fuel injection as standard, and adds high-pressure direct injection control via the optional HP package — the same dual-bank HP architecture as the MS 6.3 EVO but with 17 additional analog input channels available.
The expanded output complement — 19 freely configurable channels covering H-bridge, high-side PWM, and low-side PWM configurations — supports complex ancillary device control beyond the engine itself: active aerodynamic actuators, variable suspension systems, transmission solenoids, and cooling system management. Two independent K-type EGT thermocouple inputs allow direct exhaust temperature monitoring on separate cylinder banks or turbocharger turbine inlets without additional signal conditioning.
The MS 6.4 EVO is confirmed to be used in GT3 homologation programmes including the Audi R8 LMS GT3, Lamborghini Huracán GT3, and BMW M4 GT3 — making it the GT3-proven platform in the MS 6 EVO range.
The MS 6.4 EVO runs the standard MS 6 EVO software platform in RaceCon, making it fully compatible with project files from MS 6.1, 6.2, and 6.3 installations. The only variant with a separate software platform is the MS 6.4P EVO.

FAQ
When should I choose the MS 6.4 EVO over the MS 6.3 EVO?
Choose the MS 6.4 EVO when your engine installation requires more than 21 analog inputs. Both the MS 6.3 and MS 6.4 support LP + HP injection with the optional HP package. The MS 6.4 adds 17 additional analog channels, two EGT thermocouple inputs (vs one on the 6.3), and 19 configurable output channels for complex ancillary control.
What is the difference between the MS 6.4 EVO and the MS 6.4P EVO?
The MS 6.4P EVO uses an 866 MHz CPU (vs 667 MHz on the MS 6.4), which provides approximately 30% more processing headroom for complex Customer Code Area algorithms. It also supports a 16 GB optional memory upgrade vs 4 GB on the MS 6.4. Critically, the MS 6.4P uses a dedicated, separate software version in RaceCon — it is not compatible with MS 6.4 EVO software. RaceCon project files cannot be transferred directly between the two without migration.
Does the MS 6.4 EVO require the HPI5 for GDI?
For most GDI injector types, yes. The high-pressure injection output stages in the ECU require an external power stage to deliver peak injector drive current at the voltage levels required by piezoelectric or solenoid GDI injectors. The Bosch Motorsport HPI5 connects via CAN and drives up to 5 GDI injectors.
Is the MS 6.4 EVO compatible with other MS 6 EVO software?
Yes. The MS 6.4 EVO uses the same RaceCon software platform as the MS 6.1, 6.2, and 6.3. Project files can be migrated between them. The MS 6.4P EVO is the only variant with an incompatible software branch.
What logging performance does the MS 6.4 EVO provide?
Standard logging is 100 channels at 20 Hz using 4 GB internal memory. The FULL_LOG_1 software upgrade activates 1,500 channels at 1,000 Hz. A second 4 GB logging partition is available via the FULL_LOG_2 software key.
