To be honest, I've tried the ones above, they weren't good, the best ones I've found for the xl terminals are these :- https://www.amazon.co.uk/dp/B078WNZ9FW?ref=ppx_pop_mob_ap_share Although I notice they are unavailable!

I don't think display link is the right protocol to use, you want Link G4.

If you have left the can lambda terminated then turn off the ic7 termination in the haltech software.

The find devices option is only for Link CAN Lambdas, it wont show any other devices. If the Link and the Haltech are configured correctly then you will see the data on the dash. If its not working, then have a look at runtime values in the Link software (F12) , and see if you have any CAN errors. I presume you have correctly terminated the bus (either IC 7 at end of bus with termination on and CAN Lambda termination disabled, or IC7 in the middle of the bus without termination and CAN Lambda terminated) HTH, Richard.

Can you double check can high is connected to the white wire on the can lambda and can lo is connected to the green wire. And also have you tried 500k in the speed setting as occasionally they can be set to this. HTH, Richard.

Ah ok, so maybe a voltage drop out then. Would it not have recovered when the alternator cut in though?

Also, try this CAN stream on ID 950, and then do a full log. This will help see some more of the CAN Lambda parameters. canlambda_test_stream.lcs

Your CAN Lambda is stuck in the calibration phase. Can you do is I suggested and power it from an independent source as a test. Is your Lambda sensor the one supplied with the CAN Lambda? Is it new? Does it come out of calibration phase if you log for longer?

one way to check if it is a power problem or not, is to connect the CAN lambda power and ground up to a separate power supply, usually a charged independent car battery works. See if there is any change. Failing that, i'm a bit stumped, although I would suspect Adam might be able to help in more depth. What does Lambda 1 status and Lambda 1 Error show before the engine is started? Include a full log pre start up too if possible.

Are you powering the CAN Lambda from a clean ignition switched +12Volt supply? And are you grounding it through a solid power ground?

Can you post your current map file please?

Have you tried 500kb? And are you sure your can high and can low wire s are round the right way?

CAN buses require termination at both ends. All Link ECUs are terminated inside, but CAN Lambdas are not terminated so will require a 120 Ohm resistor near the CAN Lambda connector between CAN high and CAN low. You will need to get this sorted first and then retest with find devices . HTH, Richard.

Do you see the CAN Lambda when you go to find device in the CAN settings? Also, the odd CAN Lambda is set to 500kb so you could try that speed and see if it makes any difference. Have you terminated the CAN bus with a 120 Ohm resistor at the CAN Lambda end? And make sure your CAN wiring is correct.

You have An Volt 9 set as Lambda 1. That needs turning off. You also don't have Link CAN Lambda selected in the CAN setup. (Also the CAN ID is not correct for a Link CAN Lambda, but that won't matter if you just select CAN Lambda from the drop down as your manual ID will be ignored). HTH, Richard.
