I was just surfing around random youtube videos today.. stumbled upon this video. Really caught my eye!

I myself have a reasonably good handle on carb tuning. (emphasis on reasonably :p )
But, I know a lot of us struggle with it at the best of times.
This is a pretty intriguing product.
I have a buddy with a clean '67 mustang, running my old carb (Summit Racing 600CFM 4010 style).
Tuned by me, it actually runs quite well on his car.
p.s. It was a video by this thunderhead289 that helped convince me to try that summit carb. which I was very happy with.
Since installing that carb, my buddy has really gained an interest and appreciation for the various tuning aspects of carbs. He's a quick learn.
He's always fiddling with the idle circuits, and rpm. Usually making a small mess of it since he's mostly guessing.
Then, brings his car and a 6-pack of beer to my place, so I can re-tune it for him.
Seems to me, a product like this, could benefit someone like him.

*edit*
A couple of interesting features I just noticed watching more videos.
- Ignition-Lock. You can lock-out your ignition from your phone, and walk away. Essentially making it impossible to start the car. Interesting security feature.
- rev-limiter. Clearly, the control module has the ability to "short-circuit" the coil.

I can see where his device could clean up af ratios from idle to low speed, high speed, etc.
Neat.
I did not watch the second video all the way, price?

cool product. around $400. You can get some entry level EFIs for a bit more than twice that price. I do like the cell phone wireless capabilities and the ignition lock.
pretty amazing that a youtube creator has been able to develop, manufacture, and distribute this product.

Very interesting..... I love my carb, but never "really" know its perfectly tuned.

Agree Ted! I think I have it dialed but not 100%. This would be fun. I might have to pull the trigger on this. Railroad, the AF ratio was very interesting

This is very nice equipment. I used a simple sensor w/ a memory on mine. The memory was real nice as full throttle pulls happen too fast in 2nd and the speed gets too high in 3rd. One thing that really surprised me was how far up the rev range and car speed that the idle circuit works. Somewhere in the 2000rpm area is where it tapers off. One might think that a stumble at 55-60 would be main circuit. Especially w/ an OD 5th gear it is much more idle than main. All the extra functions of the carb cheater make it a better tool than my old one was.
