Page 9: Introduction
• Modified standard Daqu is used for engines equipped with ECU (same as miniDaqu) for cases where miniDaqu does not have enough channels for all additional sensors. This is often a case for ULPower and WMFly engines. Only ECUs with CAN bus is supported (no RS-232). © Kanardia 2019-2024... -

The upper limit equals to 20 pulses per revolution at 3000 PRM or 10 pulses at 6000 RPM. On lower end this equals to 75 RPM at one pulse per revolution, 37.5 RPM at two pulses per revolution and 7.5 RPM at 10 pulses per revolution. © Kanardia 2019-2024... -
Page 11: Output Pins
Daqu has two connectors on opposite sides. One is used to connect manifold pressure hose and the other is used to connect CAN bus cable. Both connectors require some additional clearence. Four removable connectors on top are used to connect sensors. Some minimal wire clearance is required, too. © Kanardia 2019-2024... - Page 12 3: (1xZ, 2xY) Analog channels 22: (15xA, 2xB, 1xC, 2xD, 2xE) Processor Cortex M3, 60 MHz Communication CAN bus, Kanardia protocol Connector Binder 99 0414 00 05 (cable side) Table 1: Technical specifications for standard Daqu. 93.5 125.5 Figure 1: Dimensions and connection clearence of standard Daqu – Top View.

Although it seems that there is no second wire, in fact it is. The “invisible” ground wire is provided by the engine block. This means that negative terminals of selected A channel must be connected to the engine block, which acts as a second wire. © Kanardia 2019-2024... -

Thus a fuel level resistive sensor shall be connected to an E channel whenever this is possible. The current and voltage are still low enough to be safe. Figure 7 illustrates such connection. Additional wire to reference ground is not needed with E channel. See also section 1.2.1 for more details. © Kanardia 2019-2024... -
