Techedge 3H1 dual wideband system
!
3h1backs

At last, a twin input wideband system.  The 3H1 features all the functionality of the 3B1 wideband system but with a pair of lambda sensors.  Ideal for monitoring both banks of a "Vee" engine, sensing pre/post catalyst or monitoring engines such as the A-series where certain cylinders have a propensity to run leaner/richer than the rest.

The package includes a pair of the latest Bosch 7200 sensors.  You may like to consider the LA1 or LX1 displays for use with the 3H1.

  • Accuracy within 0.1 AFR (Lambda +/- 0.005).
  • 1 MB on-board logging memory
  • Socket for connection to your PC or datalogger
  • Configurable wideband up to 8 Volt output (12 bit DAC accuracy).
  • 6 analogue inputs configurable as:
    • up to 6 of 0 to 5 Volt inputs (4 differential, 2 single ended).
    • up to 4 of thermocouple inputs (all differential) .
  • Additional pulse input channel (for vehicle speed, etc.)
  • 10.5 to 19.5 Volt DC operation.
  • Simulated narrowband output.
  • RPM input from Tacho or ECU for logging.
  • Supports LSU 4.0/4.2 (Bosch 6066/7057/7200 family), LSU 4.9 as well as NTK (L1H1/L2H2) sensor (requires NTK sensor cable).
