Questions about this file
Is this original file compatible with my Scania R420?
Read the ECU identification with your tool (hardware and software numbers) and send it to us with the order; we confirm the exact original before delivery. Continental/Siemens EMS S6 and EMS S8 controllers (Scania) are identified by a 7-digit hardware number and a 7-digit software number read by the tool or shown in SDP3.
What exactly do I receive when I buy the Motorola EMS S6 original for €25?
An unmodified factory read of the Motorola EMS S6 (identified on this page) as stored in our archive — a binary file in the format produced by the original reading tool, chosen among the 25 reads listed on this page after we match your identification. No modifications, no checksum changes: it is meant to restore the ECU to its stock calibration or to serve as a reference for a tuning job.
How and when is the file delivered?
After payment we confirm the read matches the numbers on this page and release it to your account, with an email notification — usually within 3 hours, within 24 hours on business days. If your ECU reports different numbers, tell us with the order and we look for the right file before delivering anything.
Can you also tune this Motorola EMS S6 or remove EGR / AdBlue / DPF?
Yes — upload your own read through the tuning service and choose the modifications; every tuning job is quoted individually before you pay. The original on this page is useful as a backup before any modification is flashed.
