LMA-3 Multi-sensor Device (AuxBox)

The AuxBox attaches to the auxiliary input of the LM-1 or it can be integrated into the MTS serial chain. The AuxBox has 5 built-in sensors. The 5 internal sensors are: Manifold Air Pressure (MAP or Boost), Cylinder Head Temperature (CHT) or Exhaust Gas Temperature (EGT), RPM conversion (from a tach signal or inductive clamp), Acceleration, and Injector Duty Cycle (or Dwell). The internal MAP sensor is a 3-bar absolute pressure sensor, providing accurate data up to 44.1 PSIA. The temperature measurement circuit features a K-type thermocouple. The internal accelerometer features 2 axis measurements for a variety of mounting options. The AuxBox also includes 5 external inputs for connecting external sensors in lieu of the internal sensors. This allows users to log data from external sensors like TPS or MAF.

  • Provides 5 channels of data
  • 3-Bar MAP / Boost
  • RPM
  • Injector Duty Cycle
  • EGT / CHT
  • 2-Axis Accelerometer
  • MTS compliant

Another key application of the AuxBox is road testing. Even a dyno doesn’t provide as much real data as road testing. Factors like air flow, side force, and load vary significantly on a real road. Use LogWorks to view fuel mapping, perform statistical analysis, overlay graphs, and playback a log on the virtual gauges. You can also view real-time data on LogWorks’ gauges if you want to take your laptop on the road. Correlating AFR, RPM, MAP, and CHT, for example, is essential when tuning piggy-back fuel controllers, ECUs, or performance carburetors.

The AuxBox ($249) can be used with the LM-1 or with any of our MTS compatible units. The AuxBox ships with mounting hardware, serial cable, and software cd.

Installation and Setup

Installation of the AuxBox is relatively simple. Complete documentation is supplied, and the support pages, videos, application notes and tuner resources can also speed you on your way to effective tuning. Innovate also has a great network of local dealers, tuners, race shops, and dyno shops that can assist you in choosing, installing, and getting the most out of your Innovate products.
