Dave: With TunerPro RT, are you able to emulate, data trace a VE table and record the data all at the same time? With the APU1, I have tried that and when enabling data record, Tunerpro drops the data acquistion, then when reenabling it, the data trace bubble freezes on one cell in the VE table. Perhaps I am doing something that is not allowed in Tunerpro. How does one emulate, data trace and display AFR in TunerPro all at the same time forget about data recording?
