newbie but got a question installing aem wideband anybody can tell me where to connect data logging wire to ecu and where can i connect the white wire for 0-5v aux output-. been having problem with o2 sensor p0172 running rich. had cleaned ffuel injectors and will be replacing o2 sensor. i had the car dyno tuned a year ago now cel keeps coming back.
You cannot run closed loop using an aftermarket Wideband. You must have a functional OEM primary oxygen sensor to run in closed loop and keep from getting eror codes. Has the car been properly tuned on the dyno?
quote]the car was tune last year when the greddy turbo was installed. i was getting codes for running rich. i had clenaed out the 550cc injectors and was in the process of replacing o2 sensor. i had the replaced the o2 sensor about a year and half ago
the code just recently started coming up and it did not come up after tune. nad yest its kpro. i havent updated program until now so will recheck again this weekend. when i installed the aem wideband to check o2 reading its was ok-so not sure if its just a faulty o2 sensor. since i took off o2 sensor and cleaned sensor-code has not returned
got problem- i recently went to upload new kpro and it erase old calibration info and now car will not start. how can i get the car restarted. it will not start at all and no information in ecu.
