Electronic Support for Fleets and Work Trucks
In logistics, every hour a unit sits idle is money you don't get back. Our mobile lab comes to your yard and diagnoses in under 20 minutes: engine modules (PCM/ECU), emissions systems and immobilizers. Specialists in Ford Power Stroke and RAM Cummins, every generation, with 100% plug-and-play solutions.

Diesel work trucks (Ford Power Stroke, RAM Cummins, GM Duramax) depend on a complex emissions system — DPF, DEF, NOx sensors — that triggers a derate at the smallest fault: the engine cuts power and speed to force the repair. For a fleet, that means a unit stranded mid-route. The traditional path is paying for a tow to the shop or dealer, waiting for an opening, and paying for another tow back — with our Mobile Lab, the unit never leaves your yard.
The dealer's math doesn't help either: on trucks with integrated PCM and TCM, a module replacement with programming typically runs $800 to $2,200, and RAM Cummins PCM repair quotes have been reported around $1,600. On top of that comes what actually hurts an operation: two tows, the wait for a service opening, and the days the unit isn't billing. That hidden cost usually exceeds the repair itself, and it's exactly the cost on-site diagnosis eliminates.
Common symptoms
Pick the symptom to see the likely cause
Derate/limp mode
Power limited to roughly 5 mph, the truck simply won't pull — this is the PCM protecting the engine after a reading it can no longer trust, and it comes back even when the sensors involved are replaced
Traditional towing, instead of the Mobile Lab
Traditional towing
out of service: waiting for the tow, a turn at the shop, and towing it back.
Mobile Lab
for diagnostics on your lot or in your garage. The unit never leaves your control.

Maximizing return: torque and emissions
Beyond emergency repair, we do software calibration aimed at the fleet's actual profitability — not at peak numbers for a spec sheet.
- Fuel efficiency and torque: we optimize injection maps on heavy-load units. More torque low in the rev range means less engine strain pulling away loaded in city traffic and on grades, which reduces diesel consumption on a sustained basis — across a fleet running every day, that differential adds up fast
- Calibration for off-road, equipment and export use: surgical adjustment of torque limits and verification algorithms for units operating off public roads, so a false sensor alarm doesn't immobilize a mechanically sound vehicle
- Emissions conflict resolution: when a NOx or differential pressure sensor reports incorrectly and cascades into lockouts, we correct the electronic management causing the cut instead of chasing codes one at a time
The corporate intervention workflow, in 4 steps
The process is built to fit how a fleet manager or shop foreman actually operates, not to make you chase a quote.
- Step 01
Triage and immediate dispatch
You send us the symptoms and the unit's location — we assess severity remotely and dispatch the Mobile Lab, or coordinate your shipment of the module if you have your own shop
- Step 02
On-site diagnosis
With OEM-level tools we determine in under 20 minutes whether the fault is in a peripheral sensor, the harness, or the control module hardware (ECU/PCM)
- Step 03
Microcomponent-level repair
If the module is at fault, we don't force you into buying a new unit — we repair the original board or clone the data onto a replacement, preserving the vehicle's exact configuration
- Step 04
B2B billing and delivery
For active business accounts we bill on a monthly cycle, consolidating the cost of every repaired unit — the part installs plug-and-play and the vehicle is back in service the same day
Technical command by platform
Ford Power Stroke, coverage by generation
We cover the full Power Stroke line, from the classic modules to the most recent locked platforms.
- 7.3L (1999-2003)
- 6.0L (2003-2007)
- 6.4L (2008-2010)
- 6.7L (2011-2019) — open Bosch module, the most common in Miami
- 6.7L (2020-2022 and 2023-2025) — new-generation locked PCM, requiring an unlock procedure most shops don't have
- 3.0L F-150 (2018-2020) — same Bosch module as the 2011-2019 6.7L
RAM Cummins, coverage by generation
From classic Common Rail to the ultra-protected systems of the most recent generations.
- 5.9L Common Rail (2003-2007)
- 6.7L (2007.5-2012)
- 6.7L (2013-2018) — the most common in Miami
- 6.7L (2019-2021) — Security Gateway (SGW) blocks third-party diagnostics; the module itself isn't encrypted (CMF), but the SGW bypass has to be resolved first
- 6.7L (2022-2024) — CM2450B generation, the most factory-protected to date
GM Duramax, coverage by generation
The third pillar of the heavy work market in Florida, with its own profile of factory lockouts.
- 6.6L LB7, LLY, LBZ and LMM (2001-2010) — the classic Silverado and Sierra 2500/3500 generations
- 6.6L LML (2011-2016) — where the serious DEF and NOx sensor emissions lockouts begin
- 6.6L L5P (2017 onward) — factory-locked ECM; we have a dedicated page for this platform given how specific its complexity is
- 3.0L Duramax LM2 and LZ0 (2019 onward) — the diesel in the Silverado 1500, Tahoe, Yukon and Escalade, increasingly common in light fleets
Delivery vans and European fleets
Last-mile delivery in Miami runs substantially on imported vans, and we're seeing more of this segment all the time — Mercedes-Benz Sprinter and Metris, Ford Transit and Renault Master/Trafic. We work the Continental/Siemens SID208 and SID211 units in the Transit, the Bosch modules in the Sprinter (the same one the EcoDiesel runs), and the SID307/SID310/MD1CS006 platforms in the Master/Trafic. For a delivery operation, a van locked out by a DEF countdown is an entire route down — which is why this segment gets dispatch priority. Send us your VIN to confirm exact coverage.
Fleet coverage
This technical support covers repair and cloning of PCM/ECU modules, emissions lockout resolution and calibration for commercial fleets and work trucks across every platform listed above. We serve Miami, Miami-Dade, Broward and South Florida with a mobile lab, and receive modules by courier from the rest of the state. We work with delivery fleets, contractors, independent shops, body shops and dealers. Send us the make, model and symptom to confirm technical coverage.
B2B account billing
Active B2B accounts — fleets and shops/body shops — bill on a cycle rather than per repaired unit, which matters when you have several trucks rotating through the shop in the same month.
Frequently asked questions
How fast do I get my truck back on the road?
On-site diagnosis takes under 20 minutes. If the repair is at the component level, we normally return the module in 2 to 4 business days — far less than the 2-3 weeks typical for a new dealer part.
Why is on-site diagnosis better than taking it to the shop?
Because of the complete bill, not just the repair. Taking a derated truck to the dealer means a tow there, a wait for a service opening, and a tow back, plus the days the unit isn't billing. The Mobile Lab comes to your yard and determines in under 20 minutes whether the fault is a sensor, the harness or the module — in many cases it's resolved right there, without the vehicle moving.
Do you offer B2B billing for fleets with multiple vehicles?
Yes — for active business accounts we bill on a monthly cycle rather than per repaired unit, which simplifies things when several trucks pass through the shop in the same month.
My RAM is a 2019 or newer and the scan tool can't get in. Can you work on it?
Yes. Since 2018 FCA platforms ship with a Security Gateway (SGW) that blocks third-party tool access — it's why many shops can't even read codes. We resolve the SGW bypass properly and work on the module, including the CM2450B architecture in the 2022-2024 generations.
Does the work affect the fleet's factory warranty?
We repair at the component level while preserving the original programming — this isn't a modification that alters the emissions system or the factory calibration.
