Also, keep in mind the 25% (default) threshold for switching to OLF no longer applies - it falls back to the 60% (default) value in the Tuner Parameters screen. (Not that this sounds like it's related to your particular problem...)

it might possibly be running too rich. my AFRs are 9.99:1 right now @ around 5500-6000rpms. i hope this is the culprit, but then i've run 9.8:1 before in OLF while tuning the car and my plugs never misfired. i'll try to get it down to 10.XX:1 and see where that takes me. (fingers crossed)
