Why Kiwi Tuners Love It:
Built tough for NZ’s demanding motorsport and street scenes, the MonsoonX delivers elite-level performance and adaptability—without the bulk or price of full-featured race ECUs. It’s a true “tuner’s ECU" that punches well above its weight class. REVIEWS RC

Running the G4X MonsoonX on my turbo Miata and it’s been a total game changer. Easy to tune, super responsive, and packed with features you usually only see on higher-end ECUs. I’ve been recommending it to every tuner I know!

Was nervous switching ECUs, but the MonsoonX exceeded expectations. Installation was smooth and the support from Link’s community is top-notch. My Honda D-series has never run this clean and smooth. Totally worth it.
