Performance Diagnostics

Finding the root cause of limp mode

Most modern Maseratis and Ferraris log thousands of data points every minute. When a check engine light pops up on your dash, it usually points to a symptom rather than the actual problem. We don't just clear the code and send you away. Last Tuesday, we had a 2016 Huracan in the shop that two other garages couldn't fix. We plugged in our factory-level tablets and spent 2.2 hours looking at the fuel trim data across both banks while the engine reached operating temperature. It wasn't a bad sensor; it was a hairline crack in a plastic vacuum line that only opened up after three heat cycles.

Live data testing while the engine is under load

We don't just test while the car is idling in the bay. Real performance issues show up when the turbos are spooling or when the gearbox is shifting at high RPMs. We use a dedicated data logger to track ignition timing and exhaust gas temperatures during a controlled road test. If your V12 feels flat at 5,000 RPM, we can see exactly which cylinder is pulling timing. Our team of 4 mechanics has handled 143 of these specific diagnostic cases in the last 11 months, usually resolving them in a single afternoon session.

Back pressure checks and exhaust flow

For cars with our titanium exhausts or even factory systems, we often perform a back pressure check. This tells us if a catalytic converter is starting to collapse or if a valve isn't opening fully. We've seen 17 cases this year where a supposed sensor failure was actually just a physical block in the pipes. We use a digital pressure gauge that is accurate to 0.1 PSI. It's a pragmatic way to rule out mechanical blocks before you spend £1,400 on electronic modules you don't actually need. Honestly, sometimes the fix is just a 50p copper washer.

What our 90-minute diagnostic session covers

• Full scan of all 35 onboard modules including engine, gearbox, and suspension.
• Detailed review of stored vs active fault codes with a printed report for your records.
• Physical inspection of the wiring looms for heat damage or signs of rubbing.
• Live battery health test because low voltage causes 47% of ghost codes in Italian cars.

We charge a flat fee for the initial 90-minute scan. If we find the fault in 15 minutes, we spend the rest of the time checking the other modules for pending issues or software updates. We aren't here to sell you parts you don't need. We just want to give you a clear answer so you can get back to driving. By the way, we usually recommend doing this before any long trip to the continent, just for peace of mind.

Technical reports you can actually understand

After the scan, we sit down with you for 10 minutes to explain the results. We don't use technical jargon to confuse you. We'll show you the graph of your oxygen sensors or the misfire count on cylinder 4. Our goal is to give you a fixed price for the repair based on what the data shows. We've found that 83% of the cars we scan only need a minor adjustment or a single component replaced, not a whole new loom. We keep our workshop records tidy so we can compare your car's data against the last 56 Ferraris we've serviced on this same dyno.
