File requests: frequently asked questions

How long does a request take?
Most files are sourced within a few hours on working days; rare software versions can take one or two days. You receive an e-mail as soon as the file is listed, with a direct link to the product.
Do I pay before the file is found?
No. Sending a request is free. You only pay when the file is listed in the shop and you decide to buy it; then it downloads instantly.
Where do I find the hardware and software numbers?
On the ECU label, or in the identification screen of your diagnostic or flashing tool. Our guide “How to read your ECU label” on the blog shows the layout for Bosch, Continental, Denso, Delphi and Marelli units. A clear photo of the label is enough for us.
Can you modify my own read (immo off, DPF off, stage 1)?
Yes. Send your original full read by e-mail with the vehicle details and the modification you need. We prepare the file on your exact software version so checksums and calibration stay correct.
Which file format will I receive?
A ZIP containing the read in the format of the tool it was made with (KESS, KTAG, FLEX, PCM Flash, New Trasdata, BDM). Tell us your tool in the request and we match the format, or convert it if needed.
