DanR,
I haven't really spent too much time with the software yet. I wasn't able to figure out how to get a good graph plotting against distance, rather than time, but I'm still a newbie too. Generally I think the software looks to be robust so its likely a matter of getting better acquainted. Playing a lap in real time would be a nice feature (if in fact that is not possible) but I'm not sure how useful that is. Normally I would be just looking at corner entry (decel g, speeds), cornering forces, and exit points to analyze performance and skip the stretches in between. I like that fact that there is now an integrated start feature with chase cam so probably next year I'll add one of those units. How is the car repair/rebuild coming?

I just wanted to throw something out there about the G2X:
I was pleasantly surprised this weekend how close the laptimes displayed on my G2X matched the transponder times on the timesheets. Most of the time, well within 3/100 or 4/100 of a second.
I had one lap where I recorded a 2:04.70 on the G2X and the AMB timesheet showed a 4.714, so that one was a little off as far as the display went, but once I actually reviewed the data using the RacePak software, the number was closer to the AMB.
Anyway, the point is that the GPS on the G2X seems very accurate from a timing standpoint....
Just thought I'd throw that out there...

Yes, you are correct 100ths of a difference off - I was just noting that the display showed a .70, but later analysis of the data showed a much closer match with the actual time.
Maybe I just didn't state it that well in my original post, and maybe I'm not stating it that well now![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
It's pretty accurate

You can zoom in and out, and the exact distance traveled is shown on the upper left hand corner of the graph area next to reference and selected lap times. Also, if you select to have sectors shown on the X axis as well, it will display the sectors on top of the graph's horizontal line, which helps correlate the data between reference lap and selected laps in conjunction to distance traveled.

I'm planning on getting some kind of data logging for my 944 S2 and I'd like to know if the oe throttle position sensor is accurate enough for logging. I mean, is it just an on/off switch, made up by steps or better? Has anyone here used it for logging?

The 944S has dual on/off switch [idle and WOT]
Not sure if the S2 is the same, but I suspect it might be. Maybe someone here can clarify that??
The Turbo has a potentiometer type TPS that provides a perfect signal for logging.

It was actually quite easy once I realized that the GMR module (just a little filter that attaches to the coil wire to pickup the tach rpm) requires you to cut the wire harness to get at the power/ground/tach signal wires (and throw away the plug end) in order to install on the iq3. The instructions could just have said that, but instead were written exclusively for the G2X.
It was a little frustrating because I would gladly have bought the little $42 GMR module in the first place and saved myself the headache, but live and learn. Other than that the iq3 is a really nice unit, you should get one Gary.

Dan,
Put the GMR on the positive primary lead to the coil. Its likely that thsi lead is extended in a loop from the stock harness at the coil to your cutoff switch and back, which makes it easy.
Washer on top so that the little jaws are closed [magnetic circuit si complete] around the wire.
Easy peasy, and its all diagramed in the install notes that come with the GMR.

Myself and possibly 2 others are interested in IQ3's as well.
Does anyone have a link to the manual available? I'd like to take a look through it before purchasing.
