Your carb adjusting
automatically
in real-time
isn’t black magic in 2026
What it is & how it works
There are now over 4,000 Carb Cheater equipped vehicles in the wild — we have been blown away by the support!
“Carb Cheater Isn’t For Stupid People”
It enables those who value personal capability —
for both those who wish to learn & those who are already capable
As much as we joke about “tuning by ear”, real classic car guys know that fiddling with the idle mix screws isn’t carb tuning.
Any average guy can get an engine to simply “run”, but you are here right now because you are better than “eh, good enough”, and just living with sub-optimal performance or worse. You probably spent a decent amount of money on your engine/classic ride — makes good sense to preserve that investment.
Look, you already know your way around a carb. You know when an engine runs well, what it should feel like, and you’ve got the experience to back it up — believe me, I get it. The Carb Cheater isn’t here for the wannabes or fakers, it’s here for you, the smart and capable, bringing you something you’ve never had before: the direct feedback required to not only perfectly tune, but know it’s right — essentially dyno tuning in the palm of your hand. No more “I hope it’s right”, or “could it be better?”. Real-time AFR, vacuum, RPM, and speed, and the ability to datalog right in front of you, that you control — and that’s just the beginning with Carb Cheater.
Ah, the “auto-tune assist” mode — this is the real fun. Carb Cheater makes real-time air/fuel adjustments automatically, always trimming toward your set target. No more a static metering device in a dynamic environment, lean one day and rich the next — a carburetor’s main weakness. Your carb was always the right choice — now it can hold its tune in conditions that used to fight it. Adaptive, consistent, and still carbureted.
You get to keep your rock solid reliable carb. No expensive fail prone fuel injection swap (that you have to tune yourself anyway), no invasive install, no laptop on the damn fender. Your engine, your carburetor, your call — with eyes on what it’s actually doing for the first time, an END to guessing and hoping.
Old school simplicity, modern day advantage — that’s The Carb Cheater.
