About this app

TunerSync, by Dotson Tuning, helps you manage Accessport files and work with your tuner from Android.

ACCESSPORT FILES
Connect a supported Accessport with a USB data cable. Save datalogs to your phone and copy maps to the Accessport. Browse supported maps, logs, logging presets and screenshots, and preview custom startup screens before replacing them. Review confirmations before removing files.

WORK WITH YOUR OWN TUNER
Save your tuner's email address, select logs and send them directly from the app. Verify your reply email first, then review the recipient, notes and attachments before sending. Your tuner replies to your own email inbox. Import a .ptm map attachment from email or your phone, review it and choose when to copy it to the Accessport. A Dotson Tuning purchase or project is not required for these tools.

YOUR DOTSON TUNING PROJECT
See next steps, current maps and project instructions. Upload requested logs, keep vehicle and Accessport details together, and find previous files in File history. Project messages support photo attachments. Optional alerts open the related message or update.

ETHANOL CALCULATOR
Enter your actual tank capacity, current tank level and desired fill level in percent, and the ethanol content of your fuels. Calculate how much of each fuel to add in US gallons or liters. The calculator is included at no charge in this version. Results depend on your inputs; follow your tuner's fuel requirements.

GUIDE AND CONNECTION HELP
The offline user guide covers setup, transfers, messages, email, maps and the calculator. Firmware notices check published release notes for supported models; use COBB Accessport Manager on a compatible computer to confirm and install firmware. TunerSync does not install firmware or flash your vehicle.

REQUIREMENTS
Android 8.0 or later, USB host support, and a compatible USB data cable or adapter are required for AP transfers. Direct email requires internet access and email verification. Dotson Tuning project features require a linked portal project or inquiry. Available maps, services and log uploads depend on the project; OTS troubleshooting uploads require shop approval.

What’s new

New CSV recordings use the customer and vehicle name, when available, plus the recording date and time, making logs easier to recognize and share.
