I am trying to finish up the tune on my 2003 and my OBDII ELM-327 with Digimoto software setup is logging very slowly. I can not get any good resolution, so that being said what are you using that may work better? I was looking at the Greddy Infometer which is very nice but I do not believe I can log the data. If I am not mistaken it is all in real time with the ability to replay on the unit only. The main thing I am looking for is information on Open/closed loop operation, LTFT's, Timing, Knock, ECT, ACT and rpm to help overlay onto my Greddy graphs. I would prefer to data log to a Excel readable file but I would be willing to look at other options. A hand held unit is somewhat appealing so that having a laptop is not necessary.
