Target engines of MaxxECU RACE
  • All 1-12 cylinder engines (4-stroke)
  • Up to 8 cylinders fully sequentially
  • Up to 12 cylinders in wasted spark
MaxxECU RACE inputs
  • Intake air temperature sensor (IAT)
  • Coolant temperature sensor (CLT)
  • Throttle position sensor (TPS)
  • Lambda (WBO) sensor. Uses a sensor directly connected to the ECU without any additional electronics. Supports Bosch LSU 4.2 and 4.9
  • 2 trigger inputs. VR or digital. Automatic trigger level detection. The signals are processed by a completely separated processor for maximum performance and immunity against interference
  • 2 extra temperature sensors. Can be used as switches or control of additional functions
  • 2 knock sensor inputs
  • 6 extra 0-5V inputs. Can be used for additional sensors such as measurement oil/fuel pressure
  • 4 extra digital inputs used for example speed sensors (VR / Hall) or switches
  • 8 EGT TYPE-K/N inputs (1200C/2200F) in separate harness
MaxxECU RACE outputs
  • 8 peak/hold injector outputs. 1-2 high or low impedance injectors per output. 8A per output
  • 8 ignition outputs. 5V signal to drive ignition modules, CDI units or coils
  • 9 extra LOW DRIVING outputs for additional features. Can be adjusted to control virtually anything like fuel pumps, idle valves. GPO 1-8,10 (2A), GPO 9 (5A)
  • 2 extra +12V DRIVING outputs (GPO 15,16) (2A)
  • 4 extra motor outputs (ex E-Throttle). GPO 11-14 (2A)
MaxxECU RACE technical
  • CAN bus for expansion modules, OEM vehicle CAN, OBDII
  • USB communication for tuning with MTune
  • Bluetooth for connecting to mobile devices with MDash
  • 8MB memory for internal logging, up to 1000Hz.
  • Supply voltage 8-22V
  • ARM Cortex-M3 120MHz main processor. Three extra processors to handle the trigger, injectors and knock detection
  • Resolution on ignition: 0.1 degrees
  • Resolution on injectors: 0.001 ms
  • Updates the fuel and ignition calculations 2000 times per second
  • The fastest PC communication on the market
  • 50Hz sampling rate on all EGT inputs
  • 1000Hz sampling rate on all analog inputs
  • Weight: 880g
  • 155x195x40mm (including mounting points, excluding connector)
