General Motors (GM) Mail-In Module Programming
Silverado, Sierra, Tahoe, Yukon, Suburban, Escalade — cluster upgrade + mileage
Why ship your General Motors (GM) module to us
What we bring to General Motors (GM) specifically:
- Covers 2003-2024 GM truck + SUV cluster generations (analog, NBS, K2, T1)
- Mileage synced to your truck's ECM/BCM — never rolled back (illegal)
- Anti-theft / Passlock counter cleared so existing keys work on the new cluster
- Upgrade path: base trim cluster → LTZ digital cluster for the same chassis
- Plug-and-play reinstall — no dealer trip required after
- Same workflow for all GM brands: Chevy, GMC, Cadillac
General Motors (GM) services we offer
All flat-priced, all typical 24-hour bench turnaround, all with flat-rate return shipping picked at checkout.
GM Cluster Upgrade + Mileage Program
Dead gauges, dim display, or want the higher-trim cluster? We upgrade and program your GM instrument cluster with the mileage and VIN carried over correctly.
GM BCM Standalone Clone (2000-2023)
Failed GM BCM taking your lights, locks, and anti-theft with it? We clone a working BCM to a replacement — VIN, mileage, theft system and all coding preserved.
GM Global A Virginize (Used ECM)
Used Global A ECM that SPS refuses to program? We reset it to a virgin, unmarried state so GM SPS / TIS2Web will take it to your VIN.
GM VATS Delete (1986-2005)
Security light and a no-start from a worn VATS key? We disable the resistor-pellet check in your GM ECM — runs on any key, no resistor needed.
GM HMI / Radio / Cluster VIN Unlock
We clear the VIN theft-lock from a used GM HMI screen module, radio, or instrument cluster so it powers up and works in your vehicle instead of showing a Theft Lock screen. Global A era (~2014–2019) only — Global B modules are not offered.
GM E38 / E67 / E92 ECM Clone
Used GM ECM that won't start the truck? We clone your original's full data — calibration, VIN, and security — onto a matching E38, E67 or E92 so it drops in without dealer programming.
GM AFM / DOD / DFM Disable Programming
Worried the AFM lifters will take out your GM V8 — or they already did? Send your ECM and we disable AFM, DOD, or DFM in the calibration on the bench.
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.
GM BCM RPO Feature Programming
Stuck with a work-truck spec that skipped the options you actually wanted? One BCM tune enables them — RPO power locks and windows, steering-wheel controls, fog lamps, keyless entry, remote start, DRL / US-spec lighting and hyperflash delete.
GM Denali Cluster Upgrade Kit (K2)
Stuck with the base gauges in a truck that deserves better? Brand-new GM 8" Denali-style cluster, programmed to your VIN and shipped plug-and-play. No core, no salvage screen-burn, no dealer.
GM ABS / EBCM Programming (K2)
ABS light still on after swapping in a replacement EBCM? We program and configure the module to your VIN — the setup step a new module needs to work.
GM BCM — Programmed & Ready to Install
Dead GM BCM leaving lights, locks and chimes misbehaving? We supply the module, program it to your VIN and your truck's exact options, and ship it ready to bolt in — you send nothing.
GM ECM / PCM — Programmed & Ready to Install
Dead GM ECM and no donor to clone? E38, E67, E92 and E80 engine computers supplied and flashed with the current factory calibration for your exact VIN — bolt in and drive.
GM T87A TCM Clone / Unlock
Failed T87A, a swap that will not shift, or a tuner locked out of the TCM? We clone your T87A onto a donor, or unlock it for tuning — bench work, no dealer SPS session.
GM ECU IMMO-Off (E98 / E80 / E82 / E84)
LS/LT swap or standalone GM build? We remove the immobilizer requirement from the E98/E80/E82/E84 ECU on the bench so it runs outside the donor vehicle.
GM TEHCM Solenoid-Pack TCM Clone
Wrench light, "Service Transmission," harsh or no shifts, and stuck in limp mode after a valve-body or solenoid-pack swap? Mail in your original TEHCM plus a matching donor and we clone the VIN, calibration, and adaptation across on the bench so the replacement drops in — no dealer SPS programming trip.
GM ECM/PCM Cloning (E-Series)
Dead GM engine computer, or a used-ECM swap that cranks but won't start with a "theft" light? Mail in your original plus a matching donor and we clone your ECM/PCM onto it on the bench — VIN, calibration, and the anti-theft/VATS relationship carried over — so the replacement is plug-and-play with no dealer SPS trip.
GM Pass-Key III+ / Modern VATS Delete (2006-2015)
Security light, crank-no-start, or a swapped ECM on a 2006-2015 GM that still demands immobilizer authorization? We remove the ECM-side Pass-Key III+ (VATS) check on supported E-series controllers — verified from your ECM label before you ship.
Duramax LB7 / LLY FICM Repair
No-start, dead miss, or a Duramax that runs rough on half its cylinders? On an LB7 or LLY the injector drivers live in a separate FICM — we repair that module on the bench and send your original back.
Duramax E35 ECM Repair (2006-2007)
No communication, a dead ECM, or injector-driver faults on a 2006-2007 Duramax? The E35 puts the injector drivers inside the ECM — we repair that board and return your original, VIN and calibration intact.
Duramax E35B ECM Repair (LMM)
LMM Duramax down with a dead ECM, no communication, or injector-driver faults? We repair the E35B at board level and send your original back with its calibration intact.
GM Kelsey-Hayes 325 ABS Repair
ABS and brake lights on with C0265 stored on a GM truck? The Kelsey-Hayes 325 EBCM is the classic cause — we repair the module at board level and send your original back.
