The jobs general shops send away — timing chains, turbos, internal engine faults, DSG and automatic transmission failures — repaired in-house and finished properly: every job ends with the programming, coding and adaptations the car needs to drive like it left the factory.
Modern engines and gearboxes are run by their control modules. Replace a mechatronic unit, a clutch pack, injectors or a timing chain and the car still needs adaptations, coding or calibration — the step most mechanical shops can't do and most programming shops can't reach. We do both under one roof, so the car leaves fixed, adapted and fault-free.
When a modern car has a serious engine or gearbox problem, most owners get two bad options: a dealer quote for a whole new unit, or a general shop that can do the mechanical work but can't program, code or adapt the car afterwards. That last step is where many repairs go wrong — the car is back together, but it still shifts badly, idles rough or throws faults.
ECU Perform closes that gap. We diagnose with factory-level software, repair the engine or transmission in our Worcester workshop, then program and adapt the control modules with dealer-level tools — one shop, one invoice, and one conversation with your extended warranty company if you have one.
Serving Worcester, Boston, Cambridge, Newton, Framingham, Shrewsbury, Springfield, Brockton and the rest of Massachusetts — mechanical work is done at our shop at 209 Stafford St, Worcester.
The big jobs — diagnosed with data first, so you only pay for the repair the engine actually needs.
Stretched chains, failed tensioners and guides, cam-phaser and VANOS faults on BMW N20 / N55, VW / Audi EA888, Mercedes M272 / M274 and more — with the adaptations reset afterwards.
Turbo replacement, oil feed and return lines, wastegates and boost leaks — then a data log to confirm boost control is right.
Overheating, coolant loss or mixing, water pumps, thermostats and radiators — pressure-tested and verified.
Valve covers, oil filter housings, rear main seals, PCV systems and oil-consumption diagnosis.
Compression and leak-down testing to find the real cause — then repair, or a used / remanufactured engine installed and programmed to your car.
Direct-injection injectors replaced and coded, high-pressure fuel pumps, carbon build-up and misfire diagnosis.
Dual-clutch and automatic gearboxes repaired — then coded, programmed and adapted with factory software so they shift like new.
Mechatronic units, clutch packs and solenoids on DQ200, DQ250, DQ381 and DQ500 — replaced, coded and adapted with ODIS.
Fluid and filter service, valve-body and mechatronic repair, harsh-shift and flare fixes — adaptations reset with factory software.
Porsche PDK fluid service, sensor and control faults, and post-repair adaptation and calibration with PIWIS III.
Mercedes 722.9 conductor-plate and speed-sensor failures, limp mode and valve bodies — programmed and SCN coded.
Shudder, slipping and lock-up faults diagnosed with live data — repaired or replaced, then adapted.
Used or remanufactured transmissions installed, the TCU programmed or cloned to your VIN and fully adapted.
A replacement mechatronic, injector set or engine is only half the job. Without coding, adaptations and calibration the car drives badly or rejects the part entirely.
Because we program at dealer level — ECU & TCU programming and module cloning are our core work — every repair is finished in software before the car leaves.
Factory-level scan, live data, compression and leak-down tests — so the right part gets replaced.
Engine and transmission work done in-house at 209 Stafford St, Worcester.
Modules programmed, injectors coded and gearbox adaptations reset with dealer-level software.
A data-logged road test and a clean fault scan before the car is handed back.
Year, make, model and the symptoms — we'll reply with next steps and a clear estimate. Extended warranty? Tell us who it's with.
