How much power does the VF ECU Software for 991.1 Carrera add?

VF Engineering quotes 365 hp and 305 lb-ft from its ECU Software for 991.1 Porsche 911 Carrera and Carrera 4 models, gains of 20 hp and 17 lb-ft over the factory 345 hp and 288 lb-ft of the 3.4 liter flat six.

Does the software fit the Carrera 4?

Yes. VF Engineering lists one calibration for the 991.1 Carrera and Carrera 4, which share the 3.4 liter flat six. The Carrera S, 4S and GTS use the larger 3.8 liter engine and take a separate VF calibration of their own.

How is the software loaded onto the car?

VF supplies the calibration as an end-user programmable package written through the OBDII port, so the owner can install it without a workshop visit. VF Engineering states that the factory calibration can be restored from the same port at any time.

Does the software work with a manual gearbox?

The calibration works on the engine and VF Engineering lists it for the 991.1 Carrera and Carrera 4 without restriction by gearbox. The seven-speed manual or PDK keeps its factory behavior, and the flat six responds more sharply to the throttle.

Is the gain noticeable on the road?

Yes, mostly in response. VF Engineering revises ignition, fueling and throttle mapping, so the naturally aspirated flat six answers the pedal sooner and builds revs more cleanly, which is felt in everyday driving far more than the modest peak figures would suggest.

Description

VF Engineering Performance ECU Software for 991.1 Porsche 911 Carrera and Carrera 4

VF Engineering’s Performance ECU Software for 991.1 Porsche 911 Carrera and Carrera 4 is written for the base cars of the generation, powered by the naturally aspirated 3.4-liter direct-injection flat-six. VF quotes 365 hp and 305 lb-ft with the calibration installed, gains of 20 hp and 17 lb-ft over the factory 345 hp and 288 lb-ft. The 3.4-liter engine is light and eager and has always been the purist’s Carrera, and the calibration builds on that, sharpening throttle response and letting the engine climb more cleanly toward its limiter. It is a sensible first step for an owner who wants more from a base 991.1 without hardware.

About VF Engineering

VF Engineering designs supercharger and turbocharger systems, titanium exhausts and ECU and TCU calibrations from a 15,000 sq ft facility in Anaheim, Orange County, California, where it has been based for nearly two decades. Every calibration is developed in house on the company’s own Mustang AWD 500 chassis dyno, ECU boards are handled in a dedicated clean room, and new parts start in an R&D room equipped with a rapid prototyper. VF reports that more than 93 percent of its supercharger systems are still running after years of hard use, many on their second or third owner, and its engineers carry the testing discipline of the Lamborghini Super Trofeo series into every road calibration.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
