Porsche 918 Spyder 4.6 V8 Hybrid ECU Tuning – Optimized Performance | 2014–Present

This isn't a generic flash. Our 918 Spyder calibrations are developed in-house, optimized on the dyno, and tested on the street and track. Every map is built around your fuel, your hardware and how you actually drive the car — maximum power with factory-level refinement and reliability. Work on a car of this calibre begins with a conversation, not a checkout button.

Estimated on a healthy car with known-good fuel:

• 887 hp → 950 hp — estimated gain of +63 hp (combined system output)
• 940 lb-ft → 1000 lb-ft — estimated gain of +60 lb-ft (combined system output)
• Fuel maps available for 91, 93 and 100 octane
• Sharper throttle response and revised rev limits
• Calibrated for consistent performance in all conditions

The 918 Spyder pairs a 4.6L naturally aspirated V8 with two electric motors. Be realistic about where the gain comes from: the combustion engine is naturally aspirated, so there is no boost to raise, and the improvement is won through ignition timing, fuelling, throttle mapping and rev limits. On a powertrain already producing 887 hp, the figures above represent a genuine step rather than a transformation — and anyone quoting you a bigger number on a 918 should be asked exactly how.

This is a limited-production hypercar and every car has its own history. We will not build a file for a 918 without speaking to you first about the car, its service record and its current condition.

What's included:

• Custom ECU calibration developed around your fuel, hardware and driving preference
• Optimized ignition timing, fuelling and rev limits for your specific car
• Throttle response and drivability refinement
• Fuel map matched to the octane you actually run — 91, 93 or 100
• OBDII data cable shipped to you
• Same-day file turnaround once we have your stock read
• Direct consultation before any work begins

What we need from you:

• Your factory stock file, read with the cable we send you
• A complete list of current modifications
• Vehicle details and VIN
• An honest description of the car's mechanical condition and full service history
• The octane you run day to day

Supported Vehicles:

• Porsche 918 Spyder — 4.6L naturally aspirated V8 with two electric motors, 2014 to current

How to order:

• 1. Talk to us first. Get in touch before ordering so we can confirm the right calibration for your car.
• 2. Order online. We ship you an OBDII data cable — typically 2–3 days to arrive.
• 3. Read your stock file. Plug the cable into your OBD port, upload your factory file, then email it to us with a list of your current modifications.
• 4. Get your file back the same day. We email your custom calibration back the day we receive your stock read — and we'll make sure you're happy with it.

In the Southern California area? Get in touch and we can tune your car in person instead.

Before you order:

• Power figures are estimates, not guarantees. Results vary with fuel quality, altitude, ambient temperature, mechanical condition, supporting modifications and dyno methodology.
• Mechanical condition — tuning raises cylinder pressure and driveline load. The car must be sound first. Pre-existing faults revealed or accelerated by tuning are not our responsibility.
• Accurate information required — we build the file from what you tell us. An unmodified stock read and an honest description of the car, its modifications and its condition are required.
• Warranty — an ECU modification will likely void any remaining factory powertrain warranty.
• Legal use — certain calibrations are for off-road and competition use only. Compliance with federal, state and local emissions law is the buyer's responsibility.
• Risk and liability — the customer assumes the risk of modification. Our liability is limited to the price of the tuning service.

Note: Tuning services are non-refundable once the file has been delivered. The service is complete at delivery. Full terms are on our Terms of Service page.
