Firmware version in PLM not compatible with ECU ?
Posted: Mon Apr 05, 2010 7:36 amI have an oldish PLM with V1.00 firmware. I have an M800 running latest software that has dual Lambda enabled. It talks to one WB sensor via the ecu loom, and the second on (RB26 Skyline engine with two wideband sensors) via CAN BUS. At least it should... 
The ecu loses connection to the laptop as soon as the CAN BUS lead is plugged into the PLM. A UK Motec trained guy has checked the wiring and agrees I have it correct. I have tried with and without resistor terminators. He thinks I need to upgrade the firmware in the PLM. Do I need to send this in to Motec themselves, and is this a known problem? The PLM works fine driven direct, and both sensors are good, as I have tried swapping them over. Thanks.
