Critical for real-time applications:
A full 30-pin mapping table, including:
The dual CAN interface combined with the 30 I/O pins allows simultaneous monitoring of engine and transmission buses. The datasheet’s pinout guide is essential for wiring DB9 or OBD connectors.
If your “30” refers to the Bosch Motronic M1.5 (used in early 1990s BMW, Opel, Volvo, Saab), here is a free, basic pinout (complete datasheet would be 10+ pages):
| Pin | Signal | Description | |-----|--------|-------------| | 1 | Ground | Sensor ground | | 2 | Injector 1 | To injector cylinder 1 | | 5 | Injector 2 | | | 9 | Injector 3 | | | 12 | Injector 4 | (if 4-cyl) | | 13 | +12V | Main relay supply | | 14 | Ignition coil | Output to coil/driver | | 17 | TPS signal | Throttle position sensor | | 20 | Coolant temp | Sensor input | | 21 | Crank speed | From VR sensor | | 24 | O2 sensor | Lambda input | | 27 | Fuel pump relay | Control output | | 30 | Ground | Power ground |
Full datasheet requires manufacturer documentation.
Q: Is the ECUS Datasheet 30 free available in languages other than English?
A: Yes, the official download page offers Chinese (Simplified), German, and Japanese translations as separate PDFs at no extra charge.
Q: Does the free datasheet include schematics for a development board?
A: No, but it includes a reference design for the minimum support circuitry: power supply decoupling, crystal oscillator, and JTAG header.
Q: How often is the datasheet updated?
A: ECUS Technology releases errata sheets quarterly. Version 4.2 (current free version) is stable; version 5.0 is expected next quarter. The free version remains valid for all hardware revisions marked “ECUS-30 Rev B” or earlier.
Q: Can I redistribute the ECUS Datasheet 30 free?
A: Yes, under the Creative Commons Attribution-NoDerivatives 4.0 license, provided you do not modify the PDF and you credit ECUS Technology.
A genuine datasheet is not just a pinout diagram. The ECUS Datasheet 30 (free version available for download) includes 9 essential sections:
