MoTeC M1 Firmware: JRR Subaru STi 2004+

$800.00

JRR Subaru STi 2004-2021 firmware license for MoTeC M1 ECU

  • If you are a MoTeC dealer or already own an M1 ECU, you can purchase just the firmware license - no ECU purchase required 

  • This firmware package suits 2004-2021 Subaru STi vehicles with single or dual AVCS EJ engine with 36-2-2-2 crank trigger pattern, 4-1 inlet cam pattern, 2 tooth exhaust cam pattern (versions with dual AVCS) and no separate sync sensor

  • May support other Subaru models using the same crank/cam triggers and CAN protocol

  • A paddle shift gearbox control version of this firmware is also available - based on MoTeC GPR-P

Base Calibrations:

This firmware is based upon MoTeC GPR and includes the following features:

  • Includes full DCCD control - control the center differential system directly from the M1 ECU (PNP sub harness available)

  • Subaru STi OE CAN bus CAN bus integration - maintains proper vehicle operation and dash functionality

  • Supports the factory cruise control including the steering wheel controls

  • iDrive switch (if equipped) can be used for any driver switch function in the M1 (boost/throttle/fuel trim/anti lag maps etc)

  • Flex fuel control - adjust fuel, timing, boost, cold start and more based upon ethanol content

  • Two stage nitrous control - various parameters supplied to control nitrous. Includes nitrous bottle heater relay control based on nitrous pressure

  • Water injection control - with failsafe for boost/timing/fuel based on pressure sensor feedback

  • Boost aim strategy has been revised with flexible table setup options

  • Boost control system allows incorporating turbo shaft speed and turbo compressor inlet pressure into the control strategy

  • Air bypass anti-lag control - for increased ALS performance (when used with appropriate engine hardware)

  • Supports the use of AEMnet lambda devices, as well as lambda controllers with a 0-5v signal output

  • Supports direct input from Obsidian IMU/INS and Racegrade IMU

  • Supports direct input from a MoTeC/Racegrade CAN keypad

  • The lower price (compared to GPR) is due to this firmware being locked to the OE engine (unless otherwise noted). Locking is done by hard coding the crank and cam trigger pattern, cylinder number and firing order in the firmware. To change to a different engine or non stock trigger pattern requires purchasing a different firmware license. Multiple firmware licenses can be installed on a single ECU.

  • Like anything, the MoTeC M1 requires knowledge and experience to gain the best results. While we are happy to answer technical questions, purchase of this M1 firmware does not come with unlimited tuning support. We can quote tuning for your particular setup, refer you to someone in your area, or if you prefer to do it yourself (and lack the experience) then we can also quote training.

  • This firmware is for closed course competition vehicles only. It does not meet federal emissions requirements.
