Tune your carbs. Enjoy the ride
Stuttering? Flat spots? Poor gas mileage? Don't just accept a poorly tuned engine as the "character" of your classic ride—you are missing out on pure driving pleasure! With the CarbuREADER®, you take your tuning into your own hands. No waiting weeks for an expensive dyno session, and you don't need to be a carb guru. Basic wrenching skills are all it takes to get professional results.
Visibly better. It's that simple.


Advantages of the CarbuREADER® System
Rent, don't buy
Invest in a flawlessly running engine instead of pricey diagnostic gear. That just takes up space in your garage.
Why drop huge sums on a professional wideband O2 system that will just collect dust on the shelf once your carbs are dialed in? Our concept gives you absolute high-end hardware for the exact timeframe you need it. This saves your budget for the parts of your project that really matter.
Real-world conditions
You log actual street data—exactly where your classic car lives and breathes.
A static dyno isn't just expensive; it often only simulates wind flow and everyday load changes in theory. The CarbuREADER® logs your AFR (air/fuel ratio) in real life: in stop-and-go traffic, cruising down the highway, or during wide-open passes. This guarantees a tune that actually works in the real world.
Temporary setup
The CarbuREADER® is only hooked up for your data logging runs. The only things left behind are the O2 bung and the joy of driving.
Keine dauerhaft installierte Kabellage im Motorraum und keine unpassenden, modernen Zusatzanzeigen in deinem historischen Armaturenbrett. Du nutzt das System ausschließlich für die Abstimmung. Danach baust du alles wieder ab und bewahrst den cleanen Original-Look deines Klassikers zu 100%.
Full jet-selection
Kaufe das perfekte Ergebnis, nicht ein riesen Sortiment an Düsen welches in der Schublade verschwindet. Nutze unser volles Düsensortiment, zahle nur was du benötigst.
To find the right jets you need the whole kit. For driving you only need one set. It only seems natural that you just buy the set you need for driving while using our full range of jets to find the right setup. You only pay for what you actually need.
Phone Support
Stuck analyzing your data? We back you up with direct support straight from our shop.
