FAQ
Does it work with automatic transmissions?
No, this ECU is designed for manual transmission FZJ100 models.
Will it increase power straight away?
Not by itself. It provides the ability to tune fuel and ignition for supporting modifications (exhaust, intake, fueling, etc.). An experienced LinkECU tuner will help extract exactly what you want out of the car!
Can I install it myself?
Installation is straightforward for those comfortable with ECU swaps, but professional installation and most importantly tuning is highly recommended.
Through Link ECU’s authorised dealer network — with strong coverage in Australia, New Zealand, the UAE and beyond.
