Is there a gm afm / dod / dfm disable programming shop in Chicago I should use instead?
Most Chicago shops don't keep the bench equipment for gm afm / dod / dfm disable programming — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Cross-region north — about 2 days each way.
Does Illinois vehicle inspection or emissions testing affect this service?
Illinois requires emissions testing in the Chicago and Metro-East St. Louis areas; downstate counties are exempt. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Illinois and federal requirements.
Can you disable DFM (Dynamic Fuel Management) on newer Gen 5 trucks?
On many supported Gen 5 applications (E92 / E92A), DFM can be disabled in the calibration the same way AFM / DOD is on Gen 4 — after we verify your specific ECM, operating system, and calibration. Some later locked GM ECMs require unlock or upgrade processes that AutoModuleLab does not currently offer; we will tell you up front if your ECM falls outside what we support.
Do you support E90 or E93 unlocks?
No. AutoModuleLab does not currently offer E90, E93, E99, or Global B unlock or upgrade services, and we do not coordinate HP Tuners send-in upgrades. We support AFM / DOD / DFM disable on E38, E67, E92, and E92A ECMs verified by VIN and ECM label photo.
