Massive Full-Color Screen in a More Compact Package
The X4 is SCT Performance's giant leap into the future of vehicle PCM tuning and custom tuning. The SCT X4 replaced the venerable, but aging SCT X-Cal 3 and SF3 handheld tuners and offers up a massive improvement in both ergonomics, speed, versatility, and tuning capability all in one awesome device. The SCT X4 tuner has a massive 2.6" x 5.5" full-color LCD screen that makes the X4's tuning, vehicle info, datalogging, and other menus extremely easy to read and navigate. Despite the larger and more advanced screen, the X4 is actually more compact than the outgoing SCT SF3 and X-Cal 3, making it easier to store and handle during tuning or maintenance. The X4 also does away with the massive OBD-II cable that the SF3 and X-Cal 3 needed to lunk around, and replaces it with a smaller and more unassuming cable with an new port on the device itself that allows you to unplug the cable completely.
Features Built-In WiFi and the Ability to Hold 10 Custom Tunes
The larger screen is paired with a revised control interface with new buttons that are more responsive, easier to use, and less clunky than SCT's older tuners. By far the most impressive feature of the X4 is it's built-in WiFi functionality that allows it to connect wirelessly with your home PC to download new tunes, firmware, and other software without the hassles of using a USB cord. The X4 can hold up to 10 custom tunes on top of its standard canned performance tunes to give you the ability to have tuning for any applications that you find yourself or your vehicle. The X4 even has two analog ports that allow you to hook up expandable probes and sensors to read data and PIDs that aren't output through your vehicle's OBD-II port. The X4 can display a wide variety of different gauges and other performance information and even automatically rotates with the device's orientation which makes it a more than adequate vehicle monitor, especially when combined with SCT's additional suction cup mount or other vehicle map. The X4 is the last tuning device that your vehicle will ever need and will take custom tuning to a whole other level.

Many of high-quality performance parts and accessories require freight shipping due to their size, bulk, or manufacturer's preferences. Freight shipping is only available to the Continental United States (AK, HI, Puerto Rico, etc. are not able to order items that ship via freight service). It takes roughly one to three days for Stage 3 to process a freight order and carefully prepare your order for transit. After our freight carrier picks up the product, a Stage 3 representative will email you tracking information for your order.
Once your shipment has arrived in your general area, the freight carrier will contact you to schedule the actual delivery. Most freight companies can only schedule for a particular day and not a specific time, because of their volume of deliveries.
After your order is delivered, it is extremely important to completely inspect your package and items for damage before signing the Bill of Lading while the delivery personnel are still there. You are solely responsible for thoroughly inspecting your items before signing any documentation. Carefully note any damage to your items or anything unusual on the Bill of Lading. Keep a copy of your papers and contact Stage 3 immediately if there is any damage or irregularities. Damage caused by transportation qualifies you for a refund and/or replacement only if any and all damage is properly documented on the Bill of Lading.
Please keep all of the item's original packaging for up to 30 days in case your product needs to be returned. All damage claims will need to be processed by our Returns Department and require clear photographs of the damage to your parts.
Some of our products are so large that they require the use of a lift gate or dock to effectively unload. Unfortunately, we can only offer free shipping to business addresses with those products. All orders that contain products that require a business address for free shipping will be checked, and if a residential address has been selected as the shipping address, that order will be held until we contact you to either change the address or elicit further payment for delivery to a residential address.
Contact Stage 3 Motorsports or check out our standard shipping policy if you have any additional questions or concerns.
