JRR M1 package update for 2008+ Subaru STi

I am finishing an update on my MoTeC M1 firmware package for 2008-2015 Subaru STi vehicles. Until now this package was targeted primarily at full motorsport use, and only offered minimal integration with the OEM CAN system (just enough to keep the gauges working). I have now upgraded it to be fully integrated with the factory CAN system and electronics. The ABS, cruise control, and DCCD will all continue to function as standard with the installation of the MoTeC M1 ECU and this firmware.

I know there are a lot of good choices for engine tuning in the Subaru world, and my target audience is only those clients who want the highest level of control and data acquisition in their vehicle. Obviously this suits those in motorsports most, however I have been getting more higher power street/track cars that also want this same level of technology. I feel there is no better or more powerful engine control for your Subaru STi than MoTeC M1 with my firmware package.

The Subaru STi features many factory installed sensors, which can now be viewed and integrated into the M1 for data logging and also used as part of control strategies. If your car is missing some of these OEM sensors, you can also wire in your own sensors in a traditional manner. The image below shows the main channels that are now available in the STi package, no extra sensors or wiring required:

While this package transmits the necessary data to keep the factory DCCD system working correctly, many want to be able to custom tune the DCCD system for their unique driving style or requirements. My Subaru STi package contains full DCCD control, with no additional hardware or purchase required. You simply wire the DCCD actuator, control switch and a couple of other items to the M1 (that previously went to the OEM DCCD controller) and then begin mapping the DCCD directly in the M1. You can also data log all DCCD parameters directly in the M1. In addition, the M1 uses the DCCD mode display in the factory gauge cluster to indicate which map you are on. For those who have used the MoTeC SDC diff control products, you should find the functionality and capability familiar.

I also did a quick video showing how some of the signals we are receiving from the OEM sensors can be used for the M1 DCCD control. The M1 DCCD control also supports switching the DCCD maps with the factory up/down switch (requires wiring it to the M1 ECU).

In addition, the SI Drive switch can be assigned to any driver switch function in the M1. These switches include anti lag, launch control, DBW throttle targeting, fuel trims, ignition trims, boost trims, the list goes on. No additional wiring required to use the SI Drive switch. You can also assign it to more than one function at a time, as shown below:

A quick video of the factory gauge cluster from one of my test drives. The only light on after the installation of the MoTeC M1 is the security light, due to the removal of the immobilizer system.

This package is one of the JRR M1 packages eligible for an end of season contingency payout in the Rally America 2016 championship in SP class.

Attention MoTeC dealers: I am happy to do private label, customized versions of this package (or any other package I offer). This allows you to have your own unique version that suits your client base, without the expense of fully developing it yourself. There is no up front cost for this service, as I simply make a % of each one you sell. I already have dealers running private versions of this particular package. 

For any questions or comments, or if you would like to purchase one of these M1 packages please email me:

JRR Rally Packages for MoTeC M1 ECU

I am very excited to be rolling out some rally specific firmware packages for the MoTeC M1 ECU line up. This combination will bring the highest level of control and capability to popular rally platforms, along with being more affordable than most previous high quality options. Feedback from rally teams will allow me to continue to grow these firmware packages tailored to the specific needs of rally. The packages will also work quite well for a track or modified street car of the same models.

We have been testing a variety of platforms and combinations, and the initial releases will be as follows (with more to come based on demand and/or requests):

  • Mitsubishi Evolution 4G63 (supports direct ACD control)
  • Mitsubishi Evolution 4B11 (supports direct ACD control)
  • Subaru STi 2008+ (supports direct DCCS control)
  • FA20 engine package (DI FA20 engine w/o driver box, supports direct Subaru DCCS control). This package is intended for FA20 engine swaps into Subaru rally cars using custom looms. 
  • FRS/BRZ - Supports OEM car with some additional rally/race specific functionality
Aside from the level of logging you want to have on your M1, with these packages there are no other options you need to buy! They come with drive by wire control, camshaft control, anti lag, launch control, knock control, flex fuel and other general features you would expect from a high end engine management system. 

In addition, some of the packages above contain built in active diff control!! This is a HUGE cost savings. Instead of buying a separate diff controller you simply wire your diff control components to the M1 ECU and program it right from the M1 Tune software. Future growth also allows us to expand the diff control model and incorporate any channels that exist within the M1 to that control strategy. 

Please email me ( with any questions or purchase inquiries. These packages can be purchased together with an M1 ECU, or separately if you already own an M1 ECU (or if you are a MoTeC dealer just needing the software package). Full package functionality is supported by the M130 and M150 ECUs, assuming you have enough I/O available. M190 package is available by special request.

Below are some screen shots highlighting a few of the features included with the JRR Rally Packages. The Evo version is shown but all will be similar. 

The boost control system allows you to incorporate a turbo inlet pressure sensor and a turbo shaft speed sensor into the control strategy. Turbo speed limiting is handled in actual shaft speed rpm values, not weird scaled values. Boost pack pressure sensor and waste gate position sensor inputs also supported for setup and data analysis.

Intercooler spray function is included, along with full per cylinder knock control with 4 software defined center frequencies along with definable knock window and trim levels.

Full anti lag control system, which is fairly similar in function to the M800 system. The M1 rev limiting and timing control is second to none, making this and the launch control work just that much better! I have also incorporated controls to operate air bypass ALS, which is highly effective for off throttle boost. 

Here is a glimpse of the diff control. The Mitsubishi ACD is shown but the Subaru setup is similar. There are 4 pairs of tables, with half of each pair for lock under acceleration and the other half for lock under braking. There is also a road mode (0% lock) and a fully locked (100%) mode. The tables and these modes can be selected by using the driver switch functionality. This allows a momentary switch, 0-5v rotary switch, CAN message or even a Racegrade CAN Keypad to change the diff modes. Standard axis available for the tables are vehicle speed, throttle position and steering angle. Future upgrades could allow more functionality based on user demand.

In addition to standard toggle and rotary switches, the package also supports using momentary switches to control various functions. Direct input from a Racegrade CAN keypad is also supported, with ability to assign any key on the keypad to a driver switch function. Currently the keypad is only supported when there is also a PDM connected, but future upgrades may include the ability to use the keypad independently.
