MAFSync DIY Module

Just the pre-flashed translator module and connector terminals — no pre-made harness, no MAF sensor. Wire it yourself, exactly how you want it routed. Wiring guide and sensor sourcing list included.

← Looking for the Full Kit or Module + Harness instead?
Built to order — please allow up to 30 days. Every unit is assembled, flashed, and bench-tested by hand before it ships. This is the bare module for builders who want to run their own wiring — no harness or MAF sensor is included. Sold for off-road use; full terms at checkout.
