YXZ1000R Plugin ECU Datasheet

1.0 General

Emtron’s YXZ1000R Plugin ECU is built upon the outstanding foundation of the SL Series and features the same processing power and logging capacity. This lightweight package is housed in a Billet Aluminium Enclosure, designed to be plugged into the OEM harness to allow for a true “Plug and Play” install. As few inputs & outputs remain unused for User definition, CAN Bus 2 is made available providing additional I/O expandability. Other features include up to 32MB permanent memory for on-board logging, 4-channel oscilloscope function, DBW control, Knock control using digital filter technology, High Speed Ethernet communications and 3-axis G-force sensing.

5.1 CAN Bus 2 Wiring

The ECU CAN Bus 2 is reserved for Emtron CAN Bus devices (ELC1/2, ETC4/ETC8M, EIC10/EIC16M). All these CAN devices share a common power, ground and CAN pinout using a 4-way DTM (Pin 1 Ground/BLACK, Pin 2 CAN Lo/GREEN, Pin 3 CAN Hi/YELLOW, Pin 4 12V/RED). Each CAN Device must be wired directly to the ECU Header Plug:

Table 3.2 — YXZ1000R ECU Header to CAN Device wiring

Standard CAN bus precautions apply — twisted pair (min one twist per 40mm), minimise connectors, 120 ohm 0.25W termination at each END, stub length < 0.3m (ISO 11898).

5.1a Emtron CAN Gauge specific wiring

5.2 Sensor Wiring

5V VRef2 Sensor Supply (Pin B7 of ECU Header) — A 250mA 5V output designed to supply automotive sensors.

Sensor 0V Reference (Pin B16 of ECU Header) — Connect directly to the 0V (Ground) pin on any low current analog sensor. DO NOT connect the 0V Reference pin directly to the Engine Block or ECU Ground. DO NOT connect frequency-based sensor grounds to the 0V Reference pin (use Pin A1 or A2 in the ECU Header).

5.3 Ethanol Content Sensor Wiring

An Ethanol Content sensor can be wired into the ECU. The following channel assignment is recommended for the GM sensor:

NoteNOTE DO NOT connect the Ethanol Content sensor ground to the “Analog Sensor 0V Reference” — splice into the ECU Ground from Pin A1 or A2. (Ethanol Content: 50Hz = 0%, 150Hz = 100%. Fuel Temperature: 1ms = -40°C, 5ms = 125°C.) Set the Ethanol Sensor Input Source to DI 4 and the ECU will automatically decode the Ethanol Content and Fuel Temperature.

6.0 Communications

• 1× High Speed Ethernet 100Mbps for tuning software connection
• 2× CAN 2.0B 1Mbps / 6 Channels per node, total 128 messages

7.0 YXZ1000R Pinout

Connector A: Injection / Ignition / Auxiliary Outputs

(15.0A Max continuous current - wire gauge dependant)

Connector B: Signal / Power / Communications / Triggers / Knock

(15.0A Max continuous current - wire gauge dependant)

7.1 Important Notes

Analog Sensor 0V Reference (Pin B16) — Connect directly to the 0V (Ground) pin on any low current analog sensor. DO NOT connect ECU pin B16 directly to the Engine Block or ECU Ground. DO NOT connect frequency-based sensors to these pins; the sensor 0V pin should be connected to the ECU ground.

WarningWARNING Replacing the MAP Sensor for Boosted applications. The MAP sensor located on Cylinder 1 is used to synchronise the engine — do not replace this MAP sensor with an alternative item, as replacement will result in loss of 720 sync and engine start. When shifting to a boosted application, the correct MAP sensor to replace is located on Cylinder 2 (Input Channel AV3 – Manifold Pressure).

8.0 Software

Emtron’s comprehensive Emtune tuning software is used to connect to the ECU (Windows 7-10, free licence, 0.5GB RAM, Ethernet IPV4). Tuning and data analysis, PC and ECU data logging, live pause and playback, advanced tuning functions, diagnostics and oscilloscope display.
