Started a new thread for those that have the PLX and are having issues with its AFR reading being too lean in closed loop at non-PE cruise conditions.
I spoke to PLX today. The guy is a tuner. I explained the problem of accurate open loop but lean closed loop readings.
He is confident it is a tuning issue and that I should adjust (richen) my VE tables. I explained to him that others have this same problem and that two other tuners (Doug and Russ) are sure its a PLX issue ..... that closed loop reading should be 14.7
Anybody have a PLX and checked OL vs CL readings and had them match ??
