Semi Truck & Heavy Equipment ECM Programming in Massachusetts | Speed Limiter, Power, Fleet

Overview

Truck & Heavy Equipment ECM Programming in Massachusetts 🇺🇸

Owner-operators and fleets lose money every day a truck sits at a dealership waiting for a parameter change. We run dealer-level diagnostic and programming software for the major heavy-duty platforms — engine, transmission and aftertreatment — so limiter changes, power parameter upgrades, injector coding and module setup happen on your schedule, at the shop or on-site.

Bought a used truck governed at 62 mph by the previous fleet? Need PTO set up, idle shutdown adjusted, or a horsepower rating unlocked to the level your engine hardware already supports? These are parameter changes the dealer charges a premium for — we do them faster and for less. Emissions equipment always stays intact and functional: we adjust what's legal to adjust, and we diagnose and repair aftertreatment systems rather than delete them.

Speed limiter adjustment — road speed & cruise limits for owner-operators & fleets
Horsepower parameter upgrades — unlock ratings your hardware supports
Fleet parameters — idle shutdown, PTO setup, driver reward, governor settings
Injector coding & calibration after injector replacement
Aftertreatment diagnostics — DPF / SCR / DEF faults, forced regens, repairs
TCM programming — Allison & automated-manual calibrations
ECM replacement programming & module cloning for HD trucks

Available across Boston, Worcester, Springfield, Cambridge, Lowell, Brockton, Quincy, Lynn, New Bedford, Fall River, Newton and Lawrence — plus the rest of Massachusetts by mobile, in-house or mail-in service.

Questions

❓ FAQ

Can you remove the speed limiter on my semi?

We adjust road-speed and cruise parameters on trucks we service for their owners — a routine, legitimate ECM parameter change. Note that federal and company rules may govern maximum settings for commercial operation; we'll set it to what you specify within what's lawful.

Can you increase the horsepower on my truck?

Often yes. Many HD engines share hardware across several factory power ratings — we can reprogram to a higher rating the hardware supports, or adjust power parameters. We'll verify what your specific engine serial supports first.

Do you delete DPF / EGR / DEF systems?

No. Emissions deletes on road vehicles are a federal violation and we don't do them. What we do instead: properly diagnose and repair aftertreatment faults, run forced regens, and fix the root cause of derates — which solves the actual problem and keeps the truck legal.

Which trucks and equipment do you cover?

Class 3–8 diesel trucks and a wide range of equipment across the major engine and transmission platforms. Send year, make, engine model and serial — we'll confirm coverage before you commit.

Do you come to the truck?

Yes — mobile service across Massachusetts for fleets and broken-down trucks, plus in-shop work in Worcester and remote programming where supported.

My truck is in derate — can you help?

Yes. We diagnose the cause of the derate with dealer-level software, repair it, and clear the derate properly. That's usually faster and cheaper than the dealership queue.
