The response from Moates recommends an APU1 with the Ostrich 2 in order to data log. Based on the cabling in your pics, I would think that the ostrich would feed info to TunerPro where it could be logged. So I guess the question is do you also need equipment to datalog with the Ostrich2 or does it allow that function?

Thanks for the info on the wideband O2 sensor. That’s the next question I’m trying to answer. It’s almost like you’ve answered these same questions a hundred times!
