Dealer update!

Get ready to hit the rev limiter! We are extremely proud to announce a massive update covering over two decades of Honda and Acura vehicles. The Keihin (SH7058, SH72543, TC1782, and TC275) ECUs are now officially supported on your AutoTuner Tool.

This gigantic protocol covers absolutely everything: from the golden age of naturally aspirated engines screaming to 9000 RPM (the legendary K20 and F20 of the Civic Type R and S2000), to the modern 1.5T / 2.0T blocks, not forgetting the massive V6s (J35/J37) and the brand’s latest hybrid powertrains. You now have the ultimate solution to meet the colossal tuning demand from Japanese car enthusiasts.

⚡ Method: 100% OBD (Normal Read – NR) Keep it simple! Securely read and write these ECUs directly through the diagnostic port. An invaluable time-saver for your workshop.

Supported Highlights (Keihin SHxxxx & TCxxxx):

The Icons (VTEC / Type R): Honda S2000 (F20C/F22C), Civic Type R (K20A/K20Z), Integra.

Boat’s parked. Ramps are empty. Winter’s quiet
Perfect time to tune the ute that tows it.

► More torque.
► Better tow.
► Summer ready.

If last season exposed soft throttle response, sluggish mid‑range, or gear hunting under load, winter is the time to fix it.

A proper ECU tune transforms these trucks:

TOWING GAINS YOU’LL FEEL IMMEDIATELY

► +100–110Nm torque for confident ramp launches
► Stronger mid‑range pull for hills and long hauls
► Sharper throttle response for tight marina manoeuvres
► Smoother, cleaner gear shifts (autos)
► Optional emissions solutions for off‑road/competition use
► Reduced turbo‑lag and wider usable RPM range
► Your ute has more to give — we’ll unlock it before summer arrives.

Book in your winter tune & UNLEASH THE BEAST
