I have an autocal, uploaded e38 and t43 tunes using full flash on tuner's recommendation(2006 ls2 corvette A6). Car runs great with the new tunes post header install. Now when I try to datalog for finetuning, it's epic fail time. I chose record data, then selected the e38 &t43 option, the display then reads UNKNOWN PIDS and freezes. Must disconnect and reconnect for the autocal to operate normally again. I'm assuming it's something simple that I'm missing. My tuner isn't always easy to reach so I thought someone here would have a tip or two. A quick datalog how-to sticky in the forum would be a huge help to new users. Datalogging was ridiculously easy with my diablo on my srt8 300c. Thanks for any help!
