Testimonial

“After installing Hondata’s CANFlex system on my 2022 RDX, the driving experience changed completely. Throttle response is sharper, acceleration is stronger throughout the rev range, and the overall performance feels like what a factory-built Type S version of the RDX might have been—if Acura had ever made one. 

What I really appreciate is how easy the system is to live with. I can run E85, pump gas, or any mix of the two, and CANFlex adapts automatically. There’s no need to switch maps or do anything special—just fuel up and go.

Even better, all of the RDX’s drive modes—Snow, Comfort, Normal, and Sport—still work exactly as they should. It still drives like a premium SUV, but now it picks up and goes with a lot more confidence.

I’ve also been using the Hondata mobile app to keep an eye on vehicle data in real time, including monitoring ethanol content after fill-ups. It’s quick, easy to use, and gives me peace of mind knowing exactly what’s going on under the hood.

If you own a 3rd gen RDX and want to unlock its full potential, this is absolutely a mod worth doing. Hondata really nailed it with this one.
