Questions about this file
Is this original file compatible with my Volvo Trucks B420R?
Compare the hardware number (20995620P05) and the software number (23054813P01) with the identification your tool reads from the ECU. The software number must match; a different hardware revision usually means a different file. TRW EMS2.x controllers (Volvo / Renault Trucks) use P-numbers: a hardware number such as 21323765P04 and a software number such as 22929395P01. The software upgrade number is the calibration actually loaded.
What exactly do I receive when I buy the TRW EMS2 original for €25?
An unmodified factory read of the TRW EMS2 (HW 20995620P05, SW 23054813P01, upgrade 22927961P01) as stored in our archive — a binary file in the format produced by the original reading tool. 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 TRW EMS2 or remove EGR / AdBlue / DPF?
