Hey guys, I wanna start making my 2018 SI my own so I'm looking into getting a KTuner v2.0. I understand locking it to the ECU, hooking it up to a PC to download a file, then flashing that file to the ECU, but my question is do I have have the obd2 AND the usb-to-PC plugged in at the same time?

Reason I'm asking is because I have no pc laptop but I do have a desktop, and ain't no way I'm hauling that thing out there to flash to the ECU lol.

Thanks all!

You can upload to the device with a desktop then take it to the vehicle and flash from the device. This is covered in the tutorial video. www.KTuner.com/KTunerHelp
