started up my car for first time ,after replacing wideband o2
and calibrating sensor .

idels fine but it won't go into close loop ? sensor is working,
my a/f is running 14.50 constant no changes .

close loop is nabled
high rpm is 500
low rpm is 400
temp for turning on is 110 degrees

i know its something stupid

does any one have any ideas?

 

Couple of ideas. In speaking with Mike Taylar @ FAST they are familiar with this occuring in certian bank to bank systems. This has occured more often when the exhaust was coated. It is usually resolved with an update in firmware and software. I have seen exhast leaks prevent the meter from reading anything meaningfull at less than 2500 RPM. On that particular car we had the firmware updated and the new software and all was well. They (FAST) also wanted the O2 sensor to verify the calibration was correct. I never got the straight answer as to what they changed but it all works fine now. MY guess is that the O2 calibration is not right. Call Mike Taylor and he should be able to get you some preliminary diagnostic checks that should save you some time.

 

thanks don ,

i did talk to mike at fast he said that i should ,send
out ecu,wb02,back to them .

even though it was just there 3 weeks
ago, and i got new sensor last week.


this sucks but taken me 3 years to build this car ,wats a couple
more weeks

oh well
