Features

Adds up to 21hp & 21.2ft-lb (with bolt-on’s).
Easily plugs into the stock ECU & ECU harness in minutes , no programming necessary .
Realizes the full potential of Aftermarket add-on’s like Cold-Air-Intakes & exhaust systems , as each kit comes pre-mapped for the exact set-up of each car or truck.
No end-user tuning necessary , just plug the kit into the car & you’re ready to go.
Easily upgradeable for future add-on’s.
Each kit comes with two maps : a low octane performance map & a high octane performance map, switchable from within the vehicle.
Fully tuneable by a Unichip Custom Tuner for customized add-on’s . This basically means that the Engine Management System in your ride is now as tuner friendly as the most advanced Standalone systems in the world , without sacrificing any of the factory features. This feature is unmatched by any reflash-tuning or other similar product.
Plug ‘n Play harnesses are fully Flux capable – purchase Flux when you purchase the Plug ‘n Play kit or upgrade later – Flux simply plugs into the Unichip Plug ‘n Play harness.
Plug ‘n Play kits are removed from the vehicle in minutes , returning the vehicle to stock tuning , without leaving a footprint of ever having been modified (a feature which reflash-tuning cannot match).

” I ordered a Unichip Plug ‘n Play kit for my Toyota . When I opened the box I was shocked ! I expected a micro chip , what I got was a fully functional engine management computer , together with a top quality wiring harness to connect it to my vehicle . I called the guys at Unichip & they explained the whole system to me . The Unichip comes pre-mapped to optimize my Cold Air Intake , Headers & Catback exhaust . Two maps ensure optimal timing settings with standard & premium octane fuels , as well as the best possible mixture settings. I switch between maps via a special switch . On top of all of this I can have the system re-programmed for different bolt-on configurations . I can even have the system custom-tuned ! Installation was a breeze! Now that I have the Unichip system & I understand how it works I realize that all the other so-called tuning products advertised on the internet for Toyota’s are all just gimmicks ! They’re either small resistors which connect to the MAF sensor (with no power gain) or shady “ECU reprograms” which void your ECU warranty & provide no gains whatsoever . I recommend the Unichip to anyone who prefers quality parts on their Toyota & if you don’t believe me , do your homework & compare the Unichip to anything else out there , it beats anything hands down!” Jose F , Florida .
