 Getting the most performance out of our cars is what we're constantly trying to achieve. But did you know that the first step in the upgrade path is not a bolt-on part, but rather an ECU tune? Enter the world of the most versatile plug-and-play handheld tuner on the market, where you can take your car from having fun and getting dirty on the weekend, then back to business as usual come Monday morning. Then when you're ready for a night out on the town, switch it to valet mode. That way these guys don't have too much fun with your car. Then right back to going fast. So what makes this and so much more possible? The access port. So what is an access port and what does it do? Hey everyone, it's Cody from Cobb. An access port is the easiest modification you can make to your vehicle to see instant results. Quite simply, the access port is a handheld unit that gains access to your car's ECU so that you can reprogram it by flashing maps to get the most performance out of your engine. But unlike other tuning solutions, it's not just a one-trick pony. The access port is a tool that was designed to be used over the life of your vehicle as you either add or remove modifications or to simply datalog and monitor your car's performance. So how does it all work? Each car has an ECU or engine control unit. The ECU's job is to manage the multitude of signals from your engine then makes adjustments to parameters such as air-fuel ratio, ignition timing, and boosts to make the engine run optimally. These adjustments are made using calibration tables that have predetermined values such as RPM, load, and air-fuel ratio that the ECU reads to know when to make a specific adjustment. By adjusting these values to account for premium fuels or specific modifications, the performance of your engine can be increased immediately, even in a stock vehicle. Installing an access port is as simple as connecting it to your OBD2 port, selecting the map you'd like to flash, and then pressing OK. Within minutes, your car will see significant gains, whether it's stock and just getting its first tune, or if you've made a modification and need to adjust for it. But the access port isn't just limited to flashing onto your ECU. No, it's packed with some pretty awesome features. Some of the coolest features are gauges, which allow you to monitor between one to six gauges that are completely customizable to show you what you want to see, a shift light that can be set to your desired RPM, the ability to datalog or record what the gauges are reading to monitor the health of your vehicle, access port manager software that allows you to transfer calibrations and datalogs between your access port and your computer, code reading and clearing, preloaded off-the-shelf maps for complete plug-and-play action, storage for up to 100 off-the-shelf or custom pro-tuned maps, vehicle mounting accessories with magnetic holster, and removable face plates that you can paint with your favorite color for a custom look. And the cherry on top? You're backed by the best customer support that's there when you need it. The access port, versatile, easy to use, and packed with powerful features. Are you ready?
