In my 1g dsm I had a 4.2 lsu AEM Wideband wired into my car until it burned out the actual gauge.
I switched over to a 4.9 style AEM Wideband gauge and a sensor with signal harness but I used the same power harness from the 4.2.
Would that cause any issues, it looked like the same pin out and gauge powered up but it seems to read rich on idle not sure if gauge was acting up?
If I cycle the key it won’t read stoich and eventually read lean like it should with car off..
It did initially on first startup with new sensor but not anymore.
I must add that with the car off key on the gauge will read rich
