Caterpillar 325 C4.4TDI — Caterpillar A6E2 — 5210791-04 ET852777 6455166-00
ECU tuning and emission-solution file for this exact calibration · 175hp / 750nm · 2019
About this file
This page covers one exact calibration: Caterpillar A6E2 with software 5210791-04 ET852777 6455166-00, as indexed on the Caterpillar 325 C4.4TDI. Work is done on your own original read — we do not send a generic file for the controller family, because two vehicles sharing a controller can carry different maps, limiters and diagnostics.
Send the file exactly as your tool saved it and tell us which tool produced it. You get the modified file back in the same format, with the checksum corrected, ready to write. Turnaround is 1–3 hours for the solutions listed as available below.
If your readout shows a different software number from the same family, use the version list at the bottom of the page — every calibration we have indexed has its own page.
Everything on this page is reference information. Not finding your exact version here does not mean we cannot do it — a solution can be developed for any calibration. Create an order on the file service and send us the original read.
