Currently own a obd1 p28 s300 and a innovate lc1 wide band. Looking Datalogg my wide band into my ecu and setup lean out protection. Want to use the d10 ELD circuit but on my ecu plug there is currently no wire in there from factory.
I have added and extra pin from a Spair plug I had. Wired the 5v signal back into the ecu. Setup the voltage limits in smanager etc but still not seeing any wide band value on the smanager software. The grounds also have perfect potential between my wide band and ecu ground.
What am I missing or not doing correctly ? I have been told there may be resistors on the ecu board I may have to remove ? Advice would be great. Specifically in regards to r136 and r138
update, here is a photo of my ecu in regards to the resistors, it appears i dont have ru 138
