[email protected] Posted February 3, 2021 Report Share Posted February 3, 2021 The link can lambda i installed today reads in lambda scale. Is that because I am using a modeled fuel table and not a traditional fuel table? Can I have it reading in the old scale 14.7 ... in the modeled fuel mode? I can just understand the gauge better. Second question is why does the lambda gauge fluctuate so much at idle? It swings back and forward. The third question is when looking at the logging the internal map has a spike up and down every few seconds like a cardeo graph at a hospital. Why are the spikes there. I am using the internal map sensor on the Link G4+Storm Blue. Quote Link to comment Share on other sites More sharing options...
wastegate Posted February 3, 2021 Report Share Posted February 3, 2021 For the units used. This is purely a setup in PCLink. Lambda swinging back below and over target is just your tune and might need a bit more work in the idle control. If you have closed loop then playing with the PIDs might help settle it down. Without looking at a log it could be guessing and I'm no automotive engineer, how long apart are the spikes. I've heard of small spikes caused by the engine firing and causing pressure spikes in the plenum, guess it depends on cams, overlap etc..
