ACDelco — Delphi controllers for GM Duramax
Five controllers, one page each, with the operating systems we cover and the price in the open.
ACDelco is the GM parts brand; the hardware is Delphi. These five controllers cover the Duramax diesel range sold in the USA and Canada — the 2.8L LWN four-cylinder, the 3.0L LM2/LZ0 inline six, and the 6.6L L5P/L5D V8. Pick the controller fitted to your vehicle: each page lists its operating systems, the vehicles that carry it, every service priced for it, and a calculator that quotes before you register.
What the five have in common: we accept and return .hpt natively, the delete package is priced without registration, and a calibration that is not on the list is normally covered within 3 hours.
Our GM Duramax guide covers the whole family — which controller sits in which truck, what a delete actually switches off, which tools read and write these ECUs, and what to expect on the dyno.
Coverage
5 controllers, 67 operating systems across the GM Duramax range — 2.8L LWN, 3.0L LM2/LZ0 and 6.6L L5P/L5D. A full delete package — DPF, EGR and SCR/AdBlue together — starts from 260 € on the 2.8L and from 455 € on the 6.6L, checksum correction included.
