Which One, GPX Pro 4 or GPX Pro 8?

I am thinking of pulling the trigger on a GPX Pro from XT Racing for my '08 R6 track bike and I was hoping to get some feedback on whether or not I should spend the extra money on the 8 input model. I would rather not limit myself in the future if I am going to want the additional inputs down the road. Is 4 good enough for a motorcycle? Any of you get the 4 and wish you had more inputs later on? Is the 8 input model more designed for automotive applications?

Here is what I am thinking so far

1. RPM
2. TPS
3. Brake (which sensor for stock MC/lever?)
4. Suspension (which potentiometer for Ohlins TTX?)

What am I missing?

I know the GPX Pro will calculate gear position, speed and acceleration internally, but do I need to add anything when I add a quick shifter?

Thanks in advance and sorry if this has been answered before but everything I am turning up on the web are just reviews or install guides.

The GPX Pro is really nice. I was talking to chiefsmokedawg today about lap timers as i really want a gpx, mainly for GPS, split times, and you can get tire temperature sensors so you know what temp they are at when riding. That's the only feature that I would want aside from what you listed.

Yeah temp sensors would be interesting, as you could look at what your tires were doing throughout a session. Another bonus that I am seeing in going with the 8 input version is the additional cable on that model has a 5V reference output that you can use to power suspension potentiometers and thermistors (temp sensors). With the 4, I guess you would have to figure out how to run your own power to these items.

Re: Which One, GPX Pro 4 or GPX Pro 8?

If you're going to hook up to suspension, I think you'd want enough channels to do front and rear. Only having one of them doesn't seem all that useful.

It's also helpful to wire into the bike's speed sensor, which allows the GPX to correctly calculate what gear you're in, regardless of gearing changes or if you're on the edge of the tire. When the bike is leaned over, it essentially makes the rear tire smaller, which screws with the gear calculation and it'll tell you you're changing gears as you lean the bike over or stand it back up. Giving it the bike's speed sensor as a reference will fix this.

Pro 8...newer model, will be supported longer than the old model IMHO.

I've got a 4 channel. I would bet money the hardware on the 8 is identical and you get the extra 4 channels through firmware. You have to open the case up to hook up the data cable, and I'm pretty sure it had a connector for a 2nd set of channels.

Either that - or they accidentally sent me a 8-channel and I'm a dumbass.

I hadn't considered the speed thing you mentioned, but I see what you are saying now. I also didn't realize they made a front sensor for the suspension, but I haven't really researched them at all yet. You are right though, having one without the other doesn't make much sense.

Re: Which One, GPX Pro 4 or GPX Pro 8?

i have the gpx pro 8 and am in love with it. Scott and I, (falls) compared data and it's really cool. I am gonna get the brake pressure sensor and eventually more sensors once i finish my trailer and suspension/new rotors and pads.

i love looking at data and i can say 100% that this helped me improve lap times after studying it at the track.

I dropped about 6 seconds in one day cause of this timer.
