SF90 Stradale Stage 3 Multimap
Ferrari’s SF90 Stradale pairs a twin-turbo 4.0-litre V8 with three electric motors. This red SF90 came to CADE Technologies in August 2025 for our Stage 2 exhaust and calibration, then returned in February 2026 for the Stage 3 multimap: a four-map calibration across both of its engine ECUs.
Stage 2 swapped the factory muffler for a lightweight titanium rear section and added heat-shielded downpipes, with a custom ECU calibration written for the new exhaust. Stage 3 adds four maps: 98, 98 High Boost, Pops and Flames.

THE CAR
- Vehicle: Ferrari SF90 Stradale

- Engine ECUs: two Bosch MED17.3.5
- Transmission: 8-speed dual-clutch
Stage 2: Exhaust and Calibration
The SF90 runs two engine ECUs, one for each bank of the V8. Before anything changed, we read both on the bench and backed up the original software.
Then came the hardware. Downpipes with integrated heat shielding went in to cut engine-bay heat soak, improve exhaust flow and stand up to high-load running. The OEM muffler came off for a lightweight titanium rear muffler section: less weight, better corrosion resistance and a sharper, more aggressive note.
With the exhaust fitted, we wrote a custom ECU calibration for it, adjusting air-fuel ratios, boost control, ignition timing and throttle response, and confirmed it under controlled conditions with data-logging.
STAGE 2 CHECKLIST
- ECUs read and backed upBoth engine ECUs read on the bench before any change.
- Heat-shielded downpipesDownpipes fitted; every fitting and seal leak-checked.
- Titanium rear sectionOEM muffler removed; alignment and clearances verified.
- Custom calibrationAir-fuel ratios, boost control, ignition timing and throttle response, confirmed with data-logging.
- Final checksClamps, hangers and fasteners verified, a leak check, and a final test under load.
Stage 3: The Multimap
In February 2026 the SF90 came back for its Stage 3 multimap. We read both engine ECUs again, then built a four-map calibration for each one, refining and re-checking the files over the following two weeks.
