2020Racing Posted November 3, 2020 Report Share Posted November 3, 2020 Hey guys. I have sent a couple of emails about this over the past few weeks. Car went for its last tune and since then was having issues with CAN Lambda. It either reads 100 or 0.00 and some times works fine. It was at Ichiban and I believe they sent some logs to you guys. I mentioned that it coincided with fitting a power tune dash. I've disconnected the dash and it hasn't changed the problem. Would changing their positions on the board have any effect or is it just a dirty signal? Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 3, 2020 Report Share Posted November 3, 2020 I cant find any logs in our tech support system here by searching "Ichiban". Can you attach the log so I can take a look. The first things to look at would be the parameters "Lambda 1 error" and "Lambda 1 status" when it is playing up. Quote Link to comment Share on other sites More sharing options...
2020Racing Posted November 3, 2020 Author Report Share Posted November 3, 2020 Thanks Adam. I will get a log and send over to you. Possibly from Scott Diver? Quote Link to comment Share on other sites More sharing options...
2020Racing Posted November 4, 2020 Author Report Share Posted November 4, 2020 I have taken a log. Please let me know if i need to do anything else for it? Log 2020-11-4 11;18;38 am.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 4, 2020 Report Share Posted November 4, 2020 That is a ECU log which has none of the required parameters logged. Can you do a short PC Log. Here is how: https://www.youtube.com/watch?v=_P1LRANeO4A Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 4, 2020 Report Share Posted November 4, 2020 The lambda controller is reporting error #54, excess pump current. This means the sensor is reporting more oxygen than air can usually contain so is usually a sign of a failing sensor. Quote Link to comment Share on other sites More sharing options...
2020Racing Posted November 4, 2020 Author Report Share Posted November 4, 2020 Ahhh. It hasn't had much use. It is a race car and used about 5 time. I will grab a sensor for it. I was told it might need resistors put in the CAN line previously but a sensor would be easier first off. Quote Link to comment Share on other sites More sharing options...
2020Racing Posted November 5, 2020 Author Report Share Posted November 5, 2020 Hey mate. I ordered an LSu4.9 from a local EFI shop. I have received a 0 281 004 150. Plug looks identical. Is this the same sensor? Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 5, 2020 Report Share Posted November 5, 2020 Im not sure, that is not a part number I have come across before. Bit of an odd one. 0 258 017 025 (long cable) & 0 258 017 052 (short cable) are the common ones that most sell. Quote Link to comment Share on other sites More sharing options...
2020Racing Posted November 6, 2020 Author Report Share Posted November 6, 2020 All sorted. Thank you. Will this need calibration? Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 6, 2020 Report Share Posted November 6, 2020 No, the Bosch factory laser trims a calibration resistor inside the connector, our CAN lambda uses this. Quote Link to comment Share on other sites More sharing options...
