2008 Chevrolet Suburban — what this service covers

We program supported GM V8 ECMs on the bench to disable AFM, DOD, or DFM so the engine stays in V8 mode where supported. You remove and ship the ECM (Chevrolet, GMC, or Cadillac 5.3 / 6.0 / 6.2L), we verify support, read and verify the calibration, disable AFM / DOD / DFM where supported, test communication, and ship it back. We support GM E38 (primary), E67, E92, and E92A ECMs after verification — E90 / E93 / E99 / Global B unlock and upgrade services are not currently offered. This is programming only: the AFM/DFM hardware stays physically installed unless you perform a separate mechanical delete, and software cannot repair already-failed lifters or cam damage. $250 flat; support is verified by VIN and ECM label photo before we accept the order.
