928sg Posted June 24 Report Share Posted June 24 been running with closed loop mode turned on, however I didn't know that it would only read Lambda 1 unless dual channel was turned on. Out of the blue this morning it started running really rich, spitting wet fuel out the exhaust. I turned on dual channel, and set up the banks. I haven't started it again. Anything else I should look out for? Before I set up dual channel, I swapped the O2 sensors at their respective plugs and the problem followed the passenger O2 sensor as far as reading high on the guage. Would this be a symptom of a bad O2 sensor? Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 24 Report Share Posted June 24 Log and tune required. How would the o2 sensor make it spit fuel out of the exhaust? There would have to be no combustion occurring for that to happen? Quote Link to comment Share on other sites More sharing options...
928sg Posted June 24 Author Report Share Posted June 24 not sure. O2 sensor is ready 60 on one bank and 11.89 on the other. I turned off closed loop and restarted and it still showed 59-60 on on bank 1. I get the log uploaded next 6-24-2024 after turning on dual bank lamda control.pclr Quote Link to comment Share on other sites More sharing options...
928sg Posted June 24 Author Report Share Posted June 24 what does lambda status 4,5,6 mean? idle log.csv Quote Link to comment Share on other sites More sharing options...
928sg Posted June 24 Author Report Share Posted June 24 after running it to get the log I don't think it was spitting fuel out the exhaust. It appears to be condensation and burned fuel residue from it running rich when I 1st got it running. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 25 Report Share Posted June 25 The link .llg log file would be more useful to me than a .csv. I would leave CLL off until it is tuned. You also still have the fuel table setup using MGP which I suggested is not suitable for ITB's earlier so you are wasting your time tuning with it set up like that.

I tried the config you sent but It wouldn't even idle and I couldn't even move the car around in the garage with it, so I had to revert back to the config I had.

928sg Posted June 25 Author Report Share Posted June 25 It was a bad Oxygen sensor. I purchased in 2019 but it had a 2015 date stamp on it. Quote Link to comment Share on other sites More sharing options...
