Can Lambda issue

[KennyJ]

i have an intermittent error on a can lambda , sometimes it works perfectly , sometimes its not found on the can.

i tried different sensor , tried seperate powerfeed

one time it worked for 10 minutes , then showed error 53 i believe it was , then dissapeared from the can.

any tips on this ?

Have you tried adding the 22uF capacitor to the power supply, as per the "Alternative" wiring diagram?

[KennyJ]

not yet , i've tried it in many different cars , swapped around with known working can lambdas and the problem chases this unit

I've tried the 22uF capacitor and I'm still having the same problem so I'm looking for the same solution.

its pretty annoying when on the dyno with the customer and then having to switch over to my aem lambda to get the job done

Can you attach a log and a copy of the tune.  Is there anything else on the bus with the lambda?  Error 53 would suggest a bus issue, like an ID conflict or excessive CAN errors.

the tune included 

log "working lambda" is another can lambda i plugged in , which worked instantly

log "lambda 2 now working" is the can lambda that didnt show up on the can before , but now works after plugging in the that other can lambda

 

wiring is a canjst cable plugged into a plugin ecu ,12v feed from battery with only a fuse

 

lambda 2 now working.llgx working lambda.llgx 2.pclx

You have a CAN lambda channel set up on both CAN ports so one will be overwriting the other.  Turn off the one that doesnt have anything connected and it will work correctly.
