Chicago FAQ
Common questions from customers shipping from Chicago.
How long does shipping take from Chicago to Arlington TX?

Do you accept modules from Chicago?
Yes — we ship to/from all 50 US states. Chicago is one of our active metros given the largest Midwest metro.
Is there a shop in Chicago that does gm afm / dod / dfm disable programming?
Most local shops in Chicago don't have the bench equipment for this kind of work — they'd send the module to a specialty workshop like ours regardless.
Can AFM / DOD be disabled by programming only?
On many supported GM Gen 4 V8 ECMs, AFM / DOD can be disabled in the calibration. This keeps the system present but disabled so the engine stays in V8 mode. Support depends on the ECM, operating system, and calibration, which we verify before accepting the order.
Can this be done on the bench?
Yes. We program supported GM ECMs on the bench using a proper bench harness and a stable, regulated power supply, then test communication before the module ships back.
Do I need to remove the engine heads?
Not for a software disable only. Removing the heads is normally part of a mechanical AFM delete or a lifter replacement job, not the programming step.
