EFI Install

Just finished up a fully complete Motorsport ECU/Dash/Expansion install with @ratchethead racing for a flawlessly prepped E36 M3.  This car has a US spec BMW S52 engine and wiring harness.

This car has nearly all of the features enabled that the Emtron system can offer.  It uses all of the factory inputs and outputs flawlessly, as well as the following additional inputs :

Twin wideband lambda sensors

Manifold pressure sensor

Fuel pressure sensor

Oil pressure sensor

Oil temperature sensor

Calibration switch (steering wheel mounted)

Fuel used reset switch (steering wheel mounted)

Ground speed limit switch (steering wheel mounted)

Traction control (dash mounted multi-position)

The extra inputs are ran to the ECU (rather than display and/or loggers) so they can be used for true speed density VE fuel modeling, load calculation, and calibration compensations.  The high input/output count of the Emtron KV8 ECU allows this.  Proper engine trips (failsafes, sensor fault detection with substitute values, etc) can also be configured.  All these auxiliary components now go to one place as well, instead of being wired to various components for data collection.

All factory plugs and sensors are used (besides narrow band lambda sensors) including the factory engine harness (Plug and play – first of its kind).  Harness additions are documented and clearly labeled for ease of use using Deutsche expansion plugs.   This system can easily be configured to add on electric throttle capability as well.  

The setup of additional sensor inputs along with a properly characterized fuel system allow the Emtron efficiency strategy to thrive.  A separate post is needed to elaborate on this system’s performance, consistency, flawless drivability, efficiency, and overall control.  Since this vehicle will be used for endurance racing, the Emtron true fuel consumption calculation will be a value tool.  

For data acquisition and display (besides the included onboard ECU logging), we enabled an advanced logging set to be received by an @AIM MXL Pista dashboard.  AIM supports a specialized Pavlotech/Emtron configuration that can receive over 60 customized ECU parameters. These can all be recorded, configured for display, and/or alarms.  Almost every sensor input and calculation from the ECU is available over the network which is just two wires going to the dashboard!  This further allowed us to create new alarm functions for fuel consumption that trip when 90% of the fuel capacity is used up, instead of watching a gauge that is inaccurate.  

On top of all of this, this car is now capable of motorsport traction control that is incomparable to any other system in this market.  The strategy uses the ECU’s internal G sensors to develop slip thresholds based on longitudinal and lateral load.  The configuration is highly comprehensive with full closed loop control.  There is also a dash mounted multi-position switch to control the traction systems sensitivity!
