DerekAE86 Posted September 7, 2023 Report Share Posted September 7, 2023 Upload the log file as well. But what sensor and controller are you using and how is it connected to the ECU? Also where in the exhaust is it fitted? Quote Link to comment Share on other sites More sharing options...

koracing Posted September 11, 2023 Report Share Posted September 11, 2023 I've noticed the AEM X-series does sometimes fluctuate a bit, but that does seem like more than I've seen. Is it possibly you have some type of minor air leak pre-o2 sensor? Do all spark plugs looks the same? It is ideal to have the sensor 18-24" away from the turbine outlet.
