[email protected] Posted June 23, 2021 Report Share Posted June 23, 2021 Hi there. I have a brand new link can lambda. I updated my Link G4+Blue Storm to the latest firmware. Then the can lambda connected according the to settings on the leaflet in the box. My issue is the can lambda will not stay connected. I double checked all the wiring. I can be sitting there with the key on and go to the place in PC Link where the button says search for can device. It finds nothing even though the setting are correct. If i reach under the bonnet and unplug the 4 wire deutz connector and plug it in again then it finds the device sometimes. I only have the one Can Device (no dash can devices) so the high and low wires go from the Link Ecu round connector straight to the deutz 4 pic connector. High and Low on one side of the connector and 12v and ground on the other. I have the 12v coming from a dedicated relay which latches when the key comes on. Am I doing something wrong? Do I need a resistor somewhere? What can I do to keep the can lambda connected? Here is a google drive link with some tune files in and also some log files in. I hope this helps you see it cutting out. https://drive.google.com/drive/folders/1pp4wM4pFTMkU1Yl46146KXpDlvy9JF8r?usp=sharing Kind Regards. Rex PS the idle adjustments that you helped me with Adam work a treat. Thanks. Quote Link to comment Share on other sites More sharing options...
JMP Posted June 23, 2021 Report Share Posted June 23, 2021 you'll need to add a terminating resistor at the end of the bus as detailed in the CAN Lambda manual Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 23, 2021 Report Share Posted June 23, 2021 What do you mean by "wont stay connected"?, lambda is working the whole time in everyone of your logs you shared. Quote Link to comment Share on other sites More sharing options...
[email protected] Posted June 23, 2021 Author Report Share Posted June 23, 2021 Hi there. I have made a video with me speaking in it as this is easier for me to communicate. I just watched the videos. I set it on 500 mbit and 1mb speed and neither worked. Video part one with key on and engine not running: Video part two with key on and engine running: Here is todays log file: https://drive.google.com/file/d/114o_Oyq0JKOmm9_u3AmDZ-gLUhOTPBv_/view?usp=sharing Here is todays tune file: https://drive.google.com/file/d/1i-WUxILxtm1EgrcVMGbvqVwhqlH5EN03/view?usp=sharing Kind Regards Rex 0220 435 947 Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 24, 2021 Report Share Posted June 24, 2021 Bit rate should set to 1Mbit unless you have reprogramed the CAN lambda. It was set to 1Mbit in your earlier map when it was working. Quote Link to comment Share on other sites More sharing options...
[email protected] Posted June 24, 2021 Author Report Share Posted June 24, 2021 Ok here comes the the confession. I used a thin piece of wire to power 12v to the Can Lambda. When I replaced it so it could get some current to the bosch sensor heating circuit things got better. I think I am on top of it staying connected now. Thanks guys for your help.
