FubarPerth Posted September 5, 2023 Report Share Posted September 5, 2023 Hi, I've been trying to get an OBD2 working on the CAN1/RS232 Port of my G4+ with no luck. I've read a few posts on this forum on how to set it up in PCLink and I seem to not have the OBD settings in the CAN Setup section. I've also found that 'CAN OBD ISO15765-4' isn't 'Unlocked'. I'm trying to get a Varex Smartbox to talk to the ECU via OBD2 as it requires EngineRPM, Speed and Throttle Position to work. I've wired in the CanHi/CanLo wiring (twisted) and put in a 120ohm Resistor at the end of the line (Varex doesn't have internal resistor). I've also checked Resistance across CanHi/CanLo which is 60ohms. How do I go about getting the CAN OBD Feature unlocked? (If that is the issue). Thanks in advance!

FubarPerth Posted September 6, 2023 Author Report Share Posted September 6, 2023 Might have found the issue.. Won't know until I get to confirm it (At work at the moment). Current Firmware on ECU is 5.1.1 Found this regarding newer firmware: G4+ Firmware Version 5.4.1.2482 - 30-04-15 New Features · Removed ECU feature unlocking. ECUs will now have feature sets as per the firmware 5.4.1 feature differentiation chart. Note, ECUs are still shipped as locked and need to be enabled but all previously purchasable features will become enabled after this firmware update. Might be why I don't have any of the Features Unlocked... Quote Link to comment Share on other sites More sharing options...
FubarPerth Posted September 8, 2023 Author Report Share Posted September 8, 2023 Firmware Update (Updated to 5.4.1) added the CAN OBD Feature. Managed to get the Varex Smart Box to connect using the settings attached. Hope this helps someone one day... Quote Link to comment Share on other sites More sharing options...
