Your custom e-tune is developed through a series of datalogs and map revisions. Calvin reviews how your car responds and adjusts the tune until he confirms it is complete.
Your tuning project keeps your vehicle details, tune files, requested logs, instructions and conversation together throughout the process.
YOUR TUNING PROCESS, IN ONE PLACE
Your tune, logs & revisions. Together.
Manage your e-tune through the Dotson Tuning customer portal. Receive maps and instructions, upload requested datalogs, and message Calvin in the same project.
See how the process works ↓Revisions & completion
Log reviews and revisions have a 24-hour turnaround. There is no limit on revisions; your e-tune must be completed within six months.
Check your project instructions, the latest map notes and Calvin’s replies before continuing. Let him know about any changes to the car or fuel, or anything that is preventing you from completing the next step.
