Standard System comes with 1 wideband sensor, engine RPM (does NOT require additional rpm module as with other systems), battery voltage, warning output, and software.

System has options for 1 additional built-in wideband oxygen sensor, plus EGT thermocouple, plus 2 analog channels (RPM, pressure, flow, position, external wideband, A/F voltage output, etc.).

  •  The Warning output can be used to activate a warning light, enable fuel enrichment, shut down NOS or ignition, retard timing, etc.
  •  Recording can be started by preset RPM value or switch.
  •  Adjustable sample rates up to 100 samples per second.
