I'm using HPTuners to tune my car and I've just about got the MAF dialed in by trial and error. In Gary's tuning guide, he shows logging the MAF frequency to give you a better idea where you need to adjust the table. I tried doing this, but it does not report any data when I select it into the chart. Is HPTuners not able to see this number on a 2002 GTP or am I doing something wrong? It would be much easier having this info instead of how I've been doing it. Thanks for any help you can offer.
