The EFI Live Autocal is easily one of the most popular tuning devices in the world, and it just got that much better. With EFILive's integrated AutoCal V3 delivery platform you can supply your tunes to customers anywhere in the world. Each AC3 Autocal includes OBDII & USB Cables and can be used to tune over 600 vehicles. All Autocal V3 devices will come with one VIN Licence, and each vehicle you tune will require an additional VIN Licence. However, most custom tune files we sell will include the VIN license in the cost of the tuning. 


Remote custom tuning has never been easier! The EFI Live AC3 allows you to receive custom tune files via email, download them to your AC3, and then flash them onto your vehicle. So as long as you have an internet connection and access to a computer, you can throw these tunes on from anywhere!

The AC3 is more than just a 'generic handheld', the AutoCal delivers EFILive's renowned scan tool for your use. This allows for the collection and transmission of logged data back to the tuner for analysis. Have a DTC code that you're worried about? With this AutoCal, you also have the ability to diagnose and clear codes!

    User Guide


    Ask a Question
    • So basically I can buy tunes for multiple trucks and use the same tuner?

      That is correct! As long as you purchase a VIN license and tunes each time, you can tune up to 600 separate VIN

    • Do you have to buy every tune? Also since it's blank you buy the first tune?

      These are blank, however we do offer V3's with preloaded tunes for 01-16 Duramax and 06-2020 Cummins.
