Toyota’s FJ Cruiser, with a 6 cylinder 4.0 liter engine and automatic gearbox, made in 2015, is a very popular car for mixed daily driving and off roading. We offer an updated ECU calibration to improve its power, overall torque and add custom features, too. This is not a piggiback unit but an ECU remap that is flashed via OBD2.
By recalibrating the stock ECU we can properly setup AFR and ignition, while also gaining extra torque with the modifications of the variable valve timing system.
The custom features we can add include: removal of maximum speed limit (only for off-road/racing) , higher rev limiter and gearbox shift limiters. Also decat modifications are supported.
