Anders Reineborg Posted August 27, 2014 Report Share Posted August 27, 2014 Hi  Well i'm having trouble to get the measuring right in the Ecu I have Aem failsafe wideband 30-4900 And i'm a little confused of wich wire i should use from the Aem also White cable says AFR analog output + Brown wire says Ground analog output -  And the calibration is linear so i use caltable 5 0,5volt = 0,58lambda4,5volt = 1,23lambda When i use this calibration the gauge in the ems is way off.. Aem gauge reads 12afr and in the ems 18-22afr I installed a friends Aem 30-4100 and setup it cal to 0volt = 0,66lambda 5volt = 1,37lambda with this gauge and cal it show correctly.  But it would be nice if i could use my own wideband instead of my friends Do you have any suggestions what to do, or shall i sell it, if it perhaps it is not compatible with link?

Simon Posted August 28, 2014 Report Share Posted August 28, 2014 The ground (brown) should be connected to the sensor ground from the ECU The White will be to the AN volt input of the ECU. You will need to confirm the scaling is correct by check the voltages at the ECU. Quote Link to comment Share on other sites More sharing options...
