Multi-Sensor Device Adds 5 Channels Of Data
The LMA-3 AuxBox integrates 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.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.Features
