What do you use/like for your track day fun?

I'm looking at Harry's on the iPhone. I didn't think it could be all that accurate, but it would like to hear user feedback. Also, which version? Rookie? Grand Prix?

Check out this R&T link:

The older Vbox and Solo seem like safe bets, and I really only need 10Hz for what I'm doing. 20-40Hz would be nice, but you pay for it.

I'm leaning toward the newer Solo. 10Hz native, 20Hz interpolated.

Go Harry's and go big get the gran prix it has so many features plus multi camera (iPhone or go pro) just a good app plus I think he has a update coming out with more features. If you can't tell I have it and like it for the cost and the data overlay is cool if you have a BT Ecu link ..

Nice. Which BT OBD-II link do you like?

 

[RodMoe]

I went with the go point BT.. But check on Harry's website I think has a few he recommends .. I'm on my phone or I would link ya :-/
Ok maybe not so hard http://www.gps-laptimer.de/Compatibility.html

Okay, I'll check it out! How do your lap times compare to the official transponder times? It would be great for ghost racing.

...also I used the Cobb APv3 to data log all the various stuff you can measure. Granted, it was super cold (for CA!) but the car really never ran any warmer than driving on the street! It was very nice to have intake temps just above ambient, all the time!

If I go with the BT module, I can't run the Cobb unit too, of course. Now that I know the #s are stable, I'm good without it.

 

[RodMoe]

The gps was really good on matching times the track had so I was happy . Yes that is a drawback of the Cobb having to be hard wired to the obd port.

This one jumps out to me right away. I'm curious about the Ford-specific add-ons...

Yeah, I'll likely hard-wire my AP at some point. Good to hear about the accuracy!

In fact I was toying with getting a iPad mini and mounting it where the wonderfully useful MFT screen is ..
Then I could run it on track days as well as dash commander too.

As long as the ford stuff is up to 2014 models or will give free updates when it's avail the scan XL looks good too

I use trackaddict HD pro app. Hd video with ODBii connectivity and GPS. Costs about $7. Get a Ram mount and an elm ODBii interface and adds about $40.

You can see some examples of the exported files in low definition on my YouTube channel. Just search "MLKN IS 350".

Yeah! I happen to have a Mini iPad and a full-sized one, too. I have mounts for them too. As an aside, my big iPad is my off-road GPS for my Jeep on trips to Death Valley, etc. In many ways better than a desert racing Lowrance GPS setup!

Thanks, that was one on the list too (and in the R&T article). The board has been wonky lately, you managed to get a couple double-posts...

 

[MLKN]

Not double posts... I just forget to finish my thoughts before hitting reply. I spent way too much time researching apps and this was the best setup for the least money I could find. Ram makes awesome mounts made in USA

I'm a big fan of Racelogic's VBOX products, but that's because I work there! Seriously though, if anyone here wants help with anything related to PerformanceBox, VBOX Sport, Video VBOX, LapTimer, or whatever feel free to hit me up.

 

[McRib 1s Back]

After a couple days of research, I think I prefer the VBOX Sport for function but the Dual XGPS 160 for value. The 160 is $149.95 on Amazon:

http://www.amazon.com/gp/product/B00E65TNYE/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A2US1DWI4QT8WM

Retail on the VBOX Sport is $429 (and current Amazon price). If I can find a deal later, I'll consider it.

For what I'm doing, I regard 10Hz as better than needed (20Hz is obviously better precision, but unnecessary for my application). I'd have settled for the 5Hz previous generation Dual XGPS 150 unit (@$86, this is a good deal for bargain hunters!). So, I'll buy the 160 now and may get the VBOX later.

The bummer here is that I ALREADY have a 10Hz external GPS. My Bad Elf GPS Pro is great, but not compatible with Harry's (this is a Bad Elf issue). Anyhow, I'll keep that for my desert GPS use, and try this one too. I don't get what's up with the guys at Bad Elf...

Also for those of you doing OBD-II linking, are you just relying on an internal GPS? I think I'd value real-time GPS over OBD II values if I had to pick.
For those of you that have both BT equipped external GPS AND BT OBD-II sensors, do they play well together? I'm tempted to try a WiFi based OBD-II unit alongside my BT GPS.

As an aside for those who doubt the need for an external GPS, watch some side-by-side video comparisons on YouTube. I have an iPhone 5s and wanted to just use the internal GPS, but it simply isn't good enough at 1Hz (debatably better than previous gens).

If I'm going through the trouble of logging, I want accurate results!

Oh yeah, I bought Harry's Lap Timer, GP Edition. It looks nice and I've downloaded my local tracks!

I bought the ram mount from Amazon, but I'm still trying to figure out my OBD II sensor. I've read about connectivity issues on the Harry's Compatibility List. As mentioned in my previous post, I'm worried about using the BT external GPS *AND* a BT (or WiFi) OBD II sensor at the same time. I'm looking for feedback on users with that kind of rig.

 

[McRib 1s Back]

...I didn't realize there were so many ELM 327 OBD II options! Most are cheap knock-offs, and I would prefer to buy the real thing and not support illegal copies (Harry touched on this too).

Please link your BT and WiFi units that are proven to work with external BT GPS.
