| Model | 30-0300 |
| Output Type | Differential mode (signal ground and power supply ground are different) |
| Sensor Type | Bosch LSU 4.9 |
| Fuse | 5A |
Wideband controller with display. Can be connected to 12V battery or a 12V/5A power supply.
Typical installation is a fixed installation in the exhaust pipe, a few centimeters after the manifold junction. In dynamometers, it can be used with an adapter at the exhaust pipe outlet as explained here.
IMPORTANT
Read the manufacturer's instructions and follow the recommendations for position, mounting, and fuse.
Connection to Accudyno
Connect the grounds together
Wideband controllers with differential analog output have a negative output different from the battery negative. For them to work properly with Accudyno, all grounds must be connected at a common point, as shown in the figure, since Accudyno has common mode input, not differential.
