How to choose a tuning file service

A tuning file service turns the ECU reads you send into ready-to-write tuning files. For a workshop, picking one means picking a subcontractor: its turnaround, quality and rules become yours in front of the customer.

Here are six things to check before you open an account, and how BOBPerformance handles each of them.

What turnaround and availability should you expect?

Look for a stated turnaround and published opening hours. A car waiting on the lift needs its file, so you have to know when it will arrive, including outside office hours.

At BOBPerformance, about 72% of requests are handled automatically, within seconds. The rest are taken on by an engineer in 15 to 30 minutes, 60 minutes max even on busy days. The platform is staffed Monday to Saturday from 9 am to 6 pm, with on-call cover from 7 am to 11 pm (longer turnaround outside opening hours).

How can you judge the quality of the files?

Ask how the files are developed and tested. Files built in-house and validated on a dyno mean fewer comebacks to the workshop and fewer surprises for your customer.

BOBPerformance has been developing its own tuning software for more than 19 years. Files are tested on our 2 dynos with official diagnostic tools, and more than 50,000 tunes leave our file service every year.

Will your reading tools work with it?

Make sure the file service accepts reads from the tools you already own, as a master and as a slave. Buying new tools just to change supplier costs time and money.

At BOBPerformance, any tool able to read a BIN file works as a master. As a BOBPerformance slave, use Alientech KESS3 linked to our master account. Check the compatible tools page and the list of supported ECUs before your first read.

Is the pricing transparent?

You should know what a file costs before you order it, without asking for a quote every time. A published credit system lets you price a job for your customer in seconds.

BOBPerformance charges in credits: €9.50 excl. VAT for a single credit, less with credit packs, and no subscription. The calculator on the pricing page gives the credits for your tool, stage and options. And to judge for yourself, your first file is free.

What support comes after the file is delivered?

Expect a technical contact you can reach at known times. A datalog to review or a question about an ECU should get a quick answer.

At BOBPerformance, support follows the platform hours, Monday to Saturday from 9 am to 6 pm with on-call cover from 7 am to 11 pm. Live chat is open Monday to Friday from 9 am to 6 pm, and our team also answers through the contact page.

Who is responsible for the work on the vehicle?

The professional working on the vehicle. The file service supplies the file; checking the vehicle’s condition, writing the file, testing and compliance with the applicable rules are the workshop’s job.

A serious file service says so plainly and only serves professionals. That is BOBPerformance’s choice: we work exclusively with automotive professionals.
