darts99 Posted September 24, 2018 Report Share Posted September 24, 2018 hi again, im having issues with my 1 day old wideband. wideband is getting switched 12v and is being grounded on the ecu ground. white wire is sending signal to my stock o2 signal wire. The signal in pc link is not moving(10.0 afr) where as the wideband gauge its self is leaning out. ive been having a hard time getting the car to run and i believe this is why.v4 type r map.pclr Quote Link to comment Share on other sites More sharing options...
flipski Posted September 25, 2018 Report Share Posted September 25, 2018 1st , I wouldn't ground the wideband on the ECU. ground it to the battery. 2nd, have you tried F12 to see if the analog voltage are changing on your Analog input 6 ? instead of just looking at lambda ? You might have a wiring issue or the aem needs to be configured. Quote Link to comment Share on other sites More sharing options...
darts99 Posted September 25, 2018 Author Report Share Posted September 25, 2018 its grounded on the same ground as the ecu uses ( engine block). ive tried switching it to voltage 0-5 and got no fluctuation in voltage Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 25, 2018 Report Share Posted September 25, 2018 In your map you have Lambda 1 assigned to AN Volt 6 which is on the expansion connector. If you have wired the wideband to the stock O2 sensor input then that would be on AN Volt 4. darts99 1 Quote Link to comment Share on other sites More sharing options...
