Want an easy solution to get more top speed out of your Honda Navi? This is our Honda Navi EVI — an unrestricted performance CDI with an integrated high-output ignition coil (≈32,000 AC volts at the plug). You’ll see stronger spark, a higher RPM ceiling, quicker throttle response, and more top speed — all plug-and-play.
The Details
The stock Navi is limited to ~8,700 RPM — that rev limiter caps your speed. The EVI removes that ceiling (we’ve seen up to ~10,500 RPM in testing). Prefer to set a limit? A dial on the underside lets you choose your own RPM cap. The unit completely bypasses the factory CDI/coil and is 100% plug-and-play — no cutting or splicing.
For best results, pair the EVI with lighter variator rollers so the transmission can reach the new RPM range: (CLICK HERE)
Dialing in the limiter is a trial-and-error process — use a tach for accuracy and common sense to protect your engine.
Important Things to Note
- The EVI is unrestricted by default; set a sensible RPM limit for your build if desired.
- Higher RPM capability often requires lighter rollers to actually reach that RPM on road.
- Plug-and-play harness — no wire cutting. Mount the box in a cool, dry location.

Excellent
It's works before I was hitting 50mph now I can go up to 55-60 but down hill I think it's pass 60mph
I've already got it installed thanks in large part to the very informative video attached. I'm still currently tweaking as I don't have a tachometer. I do in the future plan to order iirc it's called a Draggy? Anyway, I'm excited to see the change in performance :)
