ACDelco E46 — OS 24001963 — Full Delete File
DPF, EGR and SCR/AdBlue deactivation with checksum correction · 3.0L Duramax LM2
About this file
Delete file for the GM 3.0L Duramax LM2 with the ACDelco E46 controller running operating system 24001963. Includes DPF, EGR and SCR/AdBlue deactivation together with the related diagnostic trouble codes and limp-home strategies, plus checksum correction. Swirl flaps, throttle valve, lambda, rev limit, speed limiter, gearbox and Stage 1 to Stage 3 — including custom calibration for hybrid turbo builds — can be added to the same order. This is a Global B controller — restore the emission system and clear the dashboard before writing the modified file. If you are new to this platform, start with our GM Duramax emissions guide — it explains how the 3.0L Duramax LM2 controllers differ and which one is in your truck.
HP Tuners workflow for OS 24001963
Most of our customers on these controllers work with HP Tuners — MPVI2+, MPVI3 or MPVI4 with VCM Suite. We work with .hpt files natively: send the file exactly as VCM Editor saved it and you get a .hpt back, ready to write. No conversion, no hex editor, nothing to install on your side.
HP Tuners supports the E46 through a send-in ECM service — the module comes out of the truck and goes to HP Tuners once, after which VCM Suite reads and writes it normally. Send us the .hpt straight from VCM Editor and you get a .hpt back.
EFILive, Alientech and bench tooling are supported too — send whatever your tool produced (.hpt, .ctz, .bin) and say which tool you use. We return the file in the same format.
DAMOS map pack for OS 24001963
For every operating system on this page we can supply a DAMOS map pack with full descriptions of the maps — typically 60 000 to 90 000 unique described maps per file, covering torque structure, injection, rail pressure, boost control, air mass, EGR, aftertreatment, limiters and diagnostics. This is what you need if you calibrate the file yourself rather than ordering a finished tune.
- OLS — standard WinOLS project — opens on any WinOLS installation.
- OLSX — WinOLS project locked to your WinOLS ID, so the pack stays yours.
- XDF — on request, built for your software — for tuners who work inside VCM Editor or another XDF-based editor instead of WinOLS.
