F90A ECU

The F90A is the Autosport connector variant of the F90RX, designed for installations demanding mil-spec connector quality in the harshest motorsport environments. Identical capability to the F90RX with 3 full bridges and up to 12 cylinders fully sequential.

Can be used for both DI (up to 10 cylinders with external GDI driver) and non-DI (up to 12 cylinders) applications, with H-Bridge circuitry for direct high-pressure fuel pump control and drive by wire throttles.

PROCESSING Powerful RISC CPU for advanced strategy execution. Custom synchronous FPGA processor for engine position tracking up to 25,000rpm.

OUTPUTS 50 user configurable pulse width modulated power outputs, including: 12 ignition coil outputs, 24 general PWM/fuel injector outputs, 8 additional PWM outputs (pin-shared), 3 full bridges also configurable as 6 half bridges or 6 PWMs.

INPUTS 28 user configurable analogue sensor inputs including 16 bipolar, inductive or hall effect speed/engine position inputs. 8 additional analogue inputs (pin-shared). 8 dedicated inputs including 4 knock inputs, 2 NTK lambda interfaces, 2 thermocouple interfaces.

INTERFACES 100 MHz full duplex Ethernet. 3 CAN 2.0B interfaces. RS232 serial interface.

MEMORY 128MB battery backed internal logging memory. Ultra fast data download via Ethernet.

POWER SUPPLY 6 to 32V input voltage range. 2 regulated 5V sensor supply outputs. 5 separately protected sensor ground inputs.

PHYSICAL 3 x Deutsch Autosport connectors — 136 pins total (not included). CNC machined sealed anodised aluminium case. 177 x 172 x 50.5 mm. Operating temperature up to 85°C. 1012 grams.
