I was trying to search the company that was talked about on the forums here, the new self learning efi system that was actually more affordable and seemed to be working good? Anybody want to point me in the right direction?
 
Until EFI gets within a couple hundred bucks of a carburetor, I will not call it "affordable".

That system is within a couple hundred dollars of some higher end carbs already. Plus, there will be a savings from the added fuel mileage and improved driveability.

some what true, but you can never have decel fuel cut on a carburetor.

That is true enough. If you know what you are doing, you can start and pretty much take off in any weather and get mpg that most people would not believe. I would typically downshift the 4 speed but it did not seem to affect mpg, probably not much total time in that mode. I was assuming RRR was in that group.
 
One thing to keep in mind when "price shopping" stuff like various home built and Megasquirt, etc etc is that most / all of them to my knowledge (except maybe hacking the GM boxes) must have a WB O2 controller separate, so you can "just" tack another 200+ on top of your figures......

I have done the WBO2, but that spoils the tuning fun. In my last car a $10 NB O2 and a 23 yr old LED bar gauge worked fine. It is important to avoid flooding the sensor. Great milage, performance, and a cleaner tailpipe than my new car. I might go closed loop, but really no need, with the stability I have seen after 1000 miles of engine break in.
 
A bunch of BS there at YB, no such thing as 150% duty-cycle. An injector only goes to 100%. WOT for drag is different than 3D lambda tuning, where table cells are configured for load based AFR control. Making a great 3D lambda requires significant effort, involving data logging, and evaluation for varied driving conditions. WOT is simple, basically one row of the table.

Not sure the added cost will be covered by increased mpg , already getting over 24 mpg highway , 95% of the driving I do , how much better could EFI DO ?

Exactly my point. There's always somethin "extra" to get.

Not sure I qualify, my focus is a narrow band about electronics, and mechanical things. I need a navigator, to leave home, and find my way back.... not joking about that.

My wife is like that. It took her forever to NOT turn the wrong way out of the driveway when we moved out here in the country.

What I know about electronics compared to you ....and Del is minuscule indeed. Microscopic even.

This... A good carb new is 500-1000.., usually a swap meet/used carb & a/good kit & proper rebuild is well under 3-400.. Would love fuelie setup. It's been 30 years since OEM adaptation,Ford & Gm hot rod F.I factory stuff is cheap. Mopar has no such SMPI/MPI setup.
 
Not really all too modular, seems kinda like one of those proprietary types. All the "value-add" garbage on the TB, "no wires thru the firewall because we even put the ecu on the TB too (so it can cook quicker)" just screams RUN AWAY.

If they did it right, the air being drawn though the throttle body would keep it quite cool, add gasoline that likes to draw heat and it will stay even cooler. Add your engine fan and I think things will be just fine. Now shut off with the hood closed would be a different story as your bay becomes a good oven, but it's only like maybe 150 degrees? Seem even 60's electronics can survive that.

In the end if you grew up with carbs, why change what your used to. If you grew up with computers and modern vehicles then EFI makes more sense to you. After doing a lot of fuel economy engineering, the biggest downside to carburetors I see is the changing of gasoline compositions to resists evaporation and additives that are all designed to be used with EFI because no OEM is using a carb. EFI will always win in the end and it's not by anyone's choice, the OEM's and fuel company's driven by government regulations drives this buss.
