Accudyno ACCU-30-0300
| Brand | Accudyno |
|---|---|
| Model | ACCU-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.
Accudyno cable included
The ACCU-30-0300 controller ships with the Accudyno Gyra/Forza connection cable pre-terminated, with the Analog− to GND junction already resolved. No additional wiring is required for Gyra/Forza.
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.
| Wire/Color | Function | Gyra/Forza |
|---|---|---|
| Red | Positive Power Supply (+) | Battery(+) |
| Black | Negative Power Supply (-) | Battery(-) |
| White | Analog Output (+) | AIN1 |
| Brown | Analog Output (-) | GND and Battery(-) |
Calibration
| Voltage | Lambda | AFR (Gasoline) |
|---|---|---|
| 0.5 V | 0.58 | 8.50 |
| 4.5 V | 1.23 | 18.00 |
Scaling formulas (see full manual):
- AFR = (2.3750 × Volts) + 7.3125
- Lambda = (0.1621 × Volts) + 0.4990
