ECU Patches, Road Tunes, and Custom Hardware — engineered down to the last byte for the cars you actually drive.
XSpec offers a range of digital and physical products to help you get the most capabilities and control out of your evo.
Our self-serve patch portal allows safe, easy Evo X ECU patching for both XSpec and Community-built patches - with comprehensive validation built-in by default. Buy credits once, redeem them for any patch, and download your files — most patches are delivered instantly.
Top up once and redeem whenever you are ready — no back-and-forth.
Pick your patches and enter your ROM ID and VIN - some patches are vin-locked.
Your patch is applied and validated against a decompiled copy of your own ROM using our proprietary M32R emulator - no guesswork.
Get your patched ROM and XML tuning file and flash with EcuFlash — 100% remote.
Every product is built on real bench and road validation — not copied maps, guesswork or generic tunes
All files, patches and tunes were developed, compiled, tested by us. No guesswork.
All products listed have multiple safety protections in place to ensure that your car can and will perform consistently.
All current and future products come with a full support guarantee - we will not leave you hanging.
