Everything you need to know before you plug in.
Getting started
A Windows PC, a supported Nissan and a K-line (KKL) USB cable with a CH340 chip, which costs about $10 (FTDI cables don't work). Our cable guide shows exactly what to buy and where.
No. VQLab reflashes the stock ECU through the OBD2 port. There are no boards to fit and nothing to solder.
VQLab checks the ECU ID, keys, block list and checksums before writing, never touches the boot block, verifies after writing, and has a dry-run mode. Always back up your stock ROM first. Lite does that for free.
9 Nissan and Infiniti car generations across 19 ECU software versions, including the Fuga, Skyline (V35 and V36), 370Z, and GT-R (experimental). The Vehicles page lists every supported software ID.
Connect with VQLab Lite (free) and it reads the software ID from your ECU, then tells you whether it is supported.
