scoobra Posted June 19, 2021 Report Share Posted June 19, 2021 hi. im coming from a differend brand standalone ecu and i am relatively new to link. i have a subaru pnp g4+ and i am trying to get wideband information to ecu directly. everything works and car idles just would make things a lot easyer to get the wideband info to the software. i have a tech edge wideband https://www.wbo2.com/2j/default.htm i have the the ground grounded to sensor ground and signal wire on AN Volt 4 (B17) what should i choose from the input list and how should i set it up properly, also what gauge should i choose from the new view list to get a proper afr wideband gauge? thank you Quote Link to comment Share on other sites More sharing options...
Confused Posted June 19, 2021 Report Share Posted June 19, 2021 By default, it looks like 0v = 9.0 AFR/0.612 lambda and 5v = 19 AFR/1.293 lambda So set up your AN Volt 4 like this: You can use Calibration tables Cal 4 - 6, configured like this: Quote Link to comment Share on other sites More sharing options...

scoobra Posted July 20, 2021 Author Report Share Posted July 20, 2021 for some reason, the reading compared to my afr gauge that is hooked straight to it is pretty different. the closest i get is with 0-5v autronic sensor, not exactly ideal but pretty close Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 20, 2021 Report Share Posted July 20, 2021 The calibration that Confused quoted should be correct. You could try temporarily switching the analog input function to "Voltage 0-5V" then compare the voltage that the ecu is receiving to the chart that Techedge show. If the voltage is wrong then it could be a wiring issue or the device could be programed to some non-default value. You can reprogram the analog output but you need a serial adapter to connect to them. Do you have WBlin- connected to sensor ground? Edit: to give you a couple of reference points; with the sensor hanging in free air the ecu should see 5.0V, with the sensor wrapped in a piece of rag soaked in brakekleen or similar it should see near 0V.

scoobra Posted July 21, 2021 Author Report Share Posted July 21, 2021 thank you. i will test that! yes WBlin- is connected to sensor ground. this worked fine in previous ecu previous ecu settings read: Linear, Span 2500, Offset 1000 Quote Link to comment Share on other sites More sharing options...
