toadthepimp Posted February 7, 2014 Share Posted February 7, 2014 Hello, swapping engines between two glanzas and one has one lambda and the other has two?? I'm slightly concerned that neither will run right when done! I'm hoping someone on here will have come across this before and can help... Thanks in advance Quote Link to post Share on other sites
AdamB Posted February 7, 2014 Share Posted February 7, 2014 Theres only 1 lambda which is at the top. The one at the bottom is a cat temp sensor and you don't need it to run the car Quote Link to post Share on other sites
Jamie5414 Posted February 7, 2014 Share Posted February 7, 2014 How many sensors on a 4efe exhaust system? Just 1 right? Quote Link to post Share on other sites
toadthepimp Posted February 7, 2014 Author Share Posted February 7, 2014 Ok cool, thanks for the surprisingly quick response! I will confirm this when both are up and running again, but thanks for putting my mind at rest Quote Link to post Share on other sites
akyakapotter Posted February 7, 2014 Share Posted February 7, 2014 (edited) yep only the top one is needed the lambda sensor Edited February 7, 2014 by akyakapotter Quote Link to post Share on other sites
Scottyboy Posted February 16, 2014 Share Posted February 16, 2014 I don't have a lamda in my ep91 should I?lol Quote Link to post Share on other sites
TurboTobz Posted February 16, 2014 Share Posted February 16, 2014 Some people say they don't do a lot, but I'm sure when I had wideband and no lambda that the AFR's weren't what they were meant to be... Quote Link to post Share on other sites
akyakapotter Posted February 16, 2014 Share Posted February 16, 2014 I got told the lambda is only used low down in the rev range up to about 2.5 - 3k then the map sensor takes over Quote Link to post Share on other sites
AdamB Posted February 16, 2014 Share Posted February 16, 2014 I got told the lambda is only used low down in the rev range up to about 2.5 - 3k then the map sensor takes over The map sensor works out the pressure entering the cylinder along with the IAT sensor to work out the volume of air. The lambda measures oxygen content after combustion has taken place. So they do two different things at two ends. Quote Link to post Share on other sites
