GM HMI / Radio / Cluster VIN Unlock

GM E38 / E67 / E92 ECM Clone

We clone your original GM ECM's full data — calibration, VIN, and security — onto a matching used/donor E38, E67, or E92 so it drops in and runs without dealer programming.

GM AFM / DOD / DFM Disable Programming

GM Global A ECM Unlock

Locked GM Global A ECM blocking read/write? Mail it in and we unlock it on the bench so your tuner or programmer can access the calibration again — for tuning, cloning, repair, or a module swap.

Speedometer / Tire & Gear Recalibration

Changed tire size or re-geared your axle and now the speedometer reads off? Mail in your supported GM ECM/PCM and we rewrite the tire-size and axle-ratio calibration on the bench so speed, odometer, and shift points read true.

GM Auto Stop-Start Disable

Tired of the engine shutting off at every red light? Mail in your supported GM ECM and we permanently disable auto stop-start in the calibration on the bench — a tune-level disable, not a button you press every drive. Primarily GM ~2014–2018 (pre-Global B); verify by VIN.

General Motors (GM) FAQ

Brand-specific questions.

Can you upgrade my base Silverado cluster to an LTZ digital one?

Yes. Source the upgraded cluster (same chassis), ship both to us, we program the upgraded cluster to your VIN, sync mileage, and clear anti-theft. The instrument options light up as the upgraded trim.

Will the truck start after I install the programmed cluster?

Yes — that's the point of our anti-theft clear step. Your existing keys will start the truck normally. No dealer trip required.

Do you do mileage rollback?

No. We only sync to actual recorded mileage of your truck (from ECM, BCM, or original cluster). Rollbacks are illegal under federal odometer law and we will not perform them under any circumstances.

My original cluster is destroyed. How do I know what mileage to sync?

Send a photo of the last known odometer reading or a recent inspection / service record. We sync the replacement cluster to that value.

Does this work for Cadillac Escalade as well as Chevy?

Yes — Escalade / ESV / EXT use the same cluster generation as Tahoe / Suburban for any given model year. Same service, same price.
