The FJ Cruiser's 1GR-FE V6 is a stout, tuneable engine that rarely gets the standalone ECU treatment it deserves.
The Toyota FJ Cruiser 1GR-FE is a capable off-road platform with a devoted following, but genuine standalone ECU support for this engine has been limited. The Boomslang PNP Wiring Harness for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.
