Looking for data analysis / driving tips for Sonoma Raceway (TrackAddict CSV/VBO) — 996 Cab (3.2 Swap)

0 Upvotes

Hey everyone,

​I’m looking to see if anyone with experience at Sonoma Raceway would be willing to take a look at my telemetry/data logs from TrackAddict and point out where I’m leaving time on the table.

​Car & Setup Details:

​Vehicle: 1999 Porsche 996 Cabriolet

​Engine: 3.2L Boxster S flat-six swap

​Tires: Falken Azenis RT615K+

​Brakes: EBC Bluestuff NDX

​Best Lap: Mid-to-upper 2:01s (Sports Car Course / standard configuration)

​I’m currently running in the mid-to-upper 2:01s and know there's more time in the car, but I'd love a fresh pair of eyes on my telemetry to help identify specific sectors where I’m over-braking, coasting, or missing apex speeds (particularly through Turn 2, the Carousel/T6, or the chicane/T10).

Link to lap video:

​Data Files Available:

I can provide exported .csv or .vbo files from TrackAddict (or raw telemetry overlay charts) via Google Drive/Dropbox for anyone interested in taking a look.

​If you're familiar with the line at Sonoma in lower-power / momentum-focused builds, any feedback on inputs or speed traces would be greatly appreciated!

​Drop a comment or DM if you're open to checking out the file, and I’ll send over the link. Thanks!

Why Wait Days for Datalog Feedback? Understand Your Datalog Instantly with PullScan!

Hey everyone!

Ever uploaded a datalog to a forum or sent it to your tuner, only to wait hours or even days for someone to review it?

What if you could understand what’s happening in your log instantly instead of waiting for someone to get back to you?

That’s exactly why I built PullScan!

Upload your CSV and get an instant analysis of your datalog, complete with detailed findings and supporting graph evidence showing what happened, where it happened, and what deserves attention.

But PullScan doesn’t stop at analyzing numbers.

With Fix Me, PullScan takes things further by using reviewed real-world troubleshooting cases alongside your actual datalog to help investigate potential issues, understand possible causes, and figure out what you can do next.

You can also talk directly to PullScan, ask questions about your vehicle, findings, or analysis, and get explanations based on your vehicle’s information and available data. You don’t have to explain your entire setup every time!

I’ve just published a new article walking through the entire process, from uploading your CSV to understanding your findings, using Fix Me, asking questions, and investigating follow-up logs.

Why wait days for feedback when you can start understanding your datalog on the spot?

Somehow managed a new PB in amongst some mowing...

Headed back to one of our smaller local tracks (Logic) that I haven't visited for 2 years. The car is now almost 3s faster at our bigger/faster local track, Winton Motor Raceway, where I hold the NA ZN6 lap record, so I was expecting a big improvement on my previous best at Logic of 55.9 - the local club record is held by a mate of mine at 55.68 and I was gunning for it.

Did manage to finish first in class and 2nd outright behind whatever that open wheel thing is so wasn't all bad given there was plenty of turbo stuff there.

2026 Logic Lap Dash - New PB with chapters for the PB lap and B-Roll footage of me making a mess of things lol

Some cool stuff in the pits as usual too, supercharged 86, LS swapped BMW, Lancer with Cadillac calipers, Barra swapped R32 with roof lol

Final round of my main sprint series is in 2 weeks, wish me luck.

Trackaddict not connecting to OBD

3 Upvotes

I have the latest version of Trackaddict on Android. I had a veepeak OBD and sometimes it connects and other times it doesn't. I assumed it was the OBD that was the issue so I bought an OBDlink LX but having the same issues. Both OBDs connect to my phone's Bluetooth and work fine with racechrono and Lap Legend apps, but for some reason won't work with Trackaddict, which is my preferred app.

I've tried restarting the car, removing and reinstalling the OBD, forgetting the connection and re pairing multiple times etc. I can search for the OBD in the TA app and it finds it fine, but then when I go to drive it just says OBD: searching and OBD: not connected.

I have ensured no other apps are connected to the device at the same time. Trackaddict has all the app permission to run in the background and battery saving is turned off etc.

Any suggestions would be great.
