Just bought my AEM FIC base, and wanted to install it before anything elese.
I was aware that some 7A-FA (also Subaru, Scion, Lexus) have problems in reading the signals from G & NE, crank and cam sensors.
Several posts on the AEM Boards reported that putting between CAM MAGI+ & CAM MAGI-, CRANK MAGI+ & Crank MAGI- 2.2K ohms resistors would avoid the FIC from sampling noise that could detect and amplify.
Now I no longer see in the RPM logs any of the spikes, but the engine is "muttering"at idle and appears to turn very rich.
Next week I should install the wideband to confirm this.
Anyone experienced this?
