Bruce Posted October 31, 2021 Report Share Posted October 31, 2021 Hi I need help I have wired in a ECU Master CAN to LAMBDA into the ECU but I am struggling to get the find it on the Link G4+ software, I have tried all the CAN ID's I could find on the internet but still no luck. I am selecting the wrong information please see attached screen shot Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 31, 2021 Report Share Posted October 31, 2021 You will need a custom stream for a 3rd party lambda device. Also, the find devices tool is only used for reprograming Link devices. If you attach your tune I will set up a custom stream. Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 1, 2021 Report Share Posted November 1, 2021 Assuming it is wired to CAN 1, try this. Bruce MAP29_10.2021 with CAN lambda.pclr Quote Link to comment Share on other sites More sharing options...
Bruce Posted November 1, 2021 Author Report Share Posted November 1, 2021 Hi Adam, I have tried this but its still not pickup the Lambda, I have checked and its is wired in on CAN1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 1, 2021 Report Share Posted November 1, 2021 Attach a log and some photos of the CAN connection to the ecu. Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 1, 2021 Report Share Posted November 1, 2021 Ok, can you load in this new map attached, unplug the CAN lambda at the 6 pin connector, then measure what voltage you have coming out of pin 2 and pin 5. One multimeter probe to any ground, the other to pin 2 or 5. Bruce MAP29_10.2021 with CAN lambda test.pclr Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 1, 2021 Report Share Posted November 1, 2021 Need a measurement on both pin 2 and 5. Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 1, 2021 Report Share Posted November 1, 2021 Ok, that looks good, we should have slightly higher than 2.5V on CAN H and slightly lower than 2.5V on CAN L when there is data so this at least confirms CAN wires are connected to the ECU correctly and data is reaching that plug. Do you have any voltage coming out of the ECU Master analog output pins? This would at least confirm the device is powered up and working.

Bruce Posted November 2, 2021 Author Report Share Posted November 2, 2021 Can i plug the can ecu master back and test analog with the map we were using to test pin 2 and 5 Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 2, 2021 Report Share Posted November 2, 2021 So all looks correct to me. And looking at your log again Im pretty sure the ecu is communicating with the device fine. There are no CAN errors and It is reporting "Lambda 1" where as it would be 0 if there was no data. How long did you run the engine for when testing? Maybe they have a start up delay? Try the attached map, I have set up an extra CAN channel to receive battery voltage reported from the lambda, so this will confirm there is communication. If CAN AN Volt 1 shows data then it is working. Bruce MAP29_10.2021 with CAN lambda test2.pclr Quote Link to comment Share on other sites More sharing options...
Bruce Posted November 3, 2021 Author Report Share Posted November 3, 2021 Hi Please see log file and I did let the car run for about 30min Log 2021-11-3 8;01;06 pm.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 3, 2021 Report Share Posted November 3, 2021 Ok, that log shows there is communication from the CAN lambda and the ecu is receiving the data correctly. It is just not working. There are no CAN errors, It is reporting Lambda = 0 and temperature = 0 the whole time. Battery voltage at the lambda (CAN AN V1) is being reported correctly as ~14.1V. So Im suspicious this thing is a dud. Attached is a new map, do us a short log with this one. I have added a couple more channels which will capture the error statuses and calibration state but not sure how much that will help - they give limited info.

Bruce Posted November 4, 2021 Author Report Share Posted November 4, 2021 Hi Thanks for the support please see attached log file, if you think that something is wrong with the Can - lambda then I will rather go buy a Link Can to lambda but when I get it will you please help to set it up.

Adamw Posted November 4, 2021 Report Share Posted November 4, 2021 The errors being reported but the Lambda are: vub low voltage. Heater open load Everything else looks ok, it reports calibration has finished and device version is LSU 4.9. I would assume that means the sensor is dead but you will need to confirm that with them.

Bruce Posted November 5, 2021 Author Report Share Posted November 5, 2021 Hi thanks a lot Do you think all the settings we did from the ecu to ecu master can lambda wires will the link can to lambda work better? Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 5, 2021 Report Share Posted November 5, 2021 To make a Link lambda work it will just be a mater of changing the CAN mode to "Link CAN lambda" and ID to 950. Quote Link to comment Share on other sites More sharing options...
