chrisvr6t 19 Posted March 1, 2014 Report Share Posted March 1, 2014 What should my wideband be reading on idle?? As it's in the 16s bouncing to low 17s ino I have a small vacume leak I thought it should be around 14.7 14.8 and at WOT around mid 10s low 11s Sent from my iPhone using Tapatalk Link to post Share on other sites

chrisvr6t 19 Posted March 1, 2014 Author Report Share Posted March 1, 2014 With closed loop control 14.5:1 to 15.0:1 I also don't have no lambda plugged in yet will that cause the high readings aswell ? Sent from my iPhone using Tapatalk Link to post Share on other sites
UnitedMotorsport 55 Posted March 1, 2014 Report Share Posted March 1, 2014 Ill interpret those double negatives as you have no lambda probe plugged in? Impossible to have closed loop control with lambda probe unplugged! If you have lambda unplugged and your reading 16 to 17 AFR on a correctly calibrated wideband, I would say your fuel pressure is too low. What AFR do you see in boost?

What AFR do you see in boost?i have not boosted it yet but when I rev it abit it does seem to go lower like in the 14s as I'm generating boost if that makes sense also using a aem wideband Sent from my iPhone using Tapatalk Link to post Share on other sites
RsvRob 6 Posted March 2, 2014 Report Share Posted March 2, 2014 Where is you wideband located? If it's in the tail pipe then I've seen plenty between 16-21 on idle. But it's fine when wot.You seem to be testing half a job. Get it all plugged up and any leaks you know of sorted 1st then take it for a drive to test for correct readings.Sent from Dagobah Link to post Share on other sites
chrisvr6t 19 Posted March 2, 2014 Author Report Share Posted March 2, 2014 It's placed 6 inches away from the turbo but yeah as said lambda is unplugged ATM as only dwn pipe is on the car Sent from my iPhone using Tapatalk Link to post Share on other sites
