Or at least mine.

What do you guys think about this?

This is a trick new EFI setup from Retrotek Speed.

Check this out

[kuhn-77]

THATS AWSOME!!!!!!!!! im deffinatly checkin that out after it comes out next spring, i have never liked EFI due to all of the wires and comp parts to it but with this its not a problem!!!!!!!!!

I'm gonna be a bit skeptical on this one. How does it monitor atmospheric conditions, exhaust conditions, engine temp, and such. Those are all parameters that a good fuel management system needs to adapt to. Just plug it into your computer and choose a setup that is most like your situation....I don't think so. We will have to wait and see on this one, but I'm not holding out much hope.

It appears to be a Speed Density system with the ability to learn as it goes. Similiar but more advanced than the HOLLEY TBI System.

Need a little more tech on it but I bet BG is wondering...

[SSon18s]

Looks expensive.

Learn, from what input? I saw no mention of mass aiflow input, exhaust gas temp input, o2 input, yada yada. I will be really suprised if we see any real data on this system.

Darn Vince...It is briefly described. Guess I will have to draw it out for you.

• The RetroTek BossEFI™ Injector Body uses port-style high-pressure fuel injectors, which are hidden in the "float bowls."
  
  
• The second component is the "Flow Control" pressure regulator. Rather than forcing a consumer to rip out their old fuel system and install complicated fuel return lines like old-fashioned aftermarket systems, BossEFI™ only requires one fuel line and a standard EFI pump.
  
  
• The "brain" behind the operation is the third and final component, the RetroTek Smart Tune Technology™ (STT) engine management system. Simply take it out of the box, plug it into any computer (desktop or laptop) with a USB or serial cable, and choose one of the pre-loaded programs that best describes your engine. Simply highlight, click, and you're done. Then install the box in your car.
  
  
• The Boss750™ Injector Body is pre-wired with a wiring harness, which snaps into the side of the control box. Add positive and ground leads from the battery, an ignition lead, a lead from the coolant temp sensor in the intake, and snap in a wide-band O2 lead, and you're ready to go.
  
  
• Hit the ignition and the basic tune will get the motor started. At that point the STT System will start checking air/fuel ratios 60 times per second, until it creates it's own fuel curve. Drive around the block and the system will continue to learn, until engine operations reach peak efficiency. As your driving style changes, the STT will continue to adapt.

FORD's EECV-IV and V adapt to different driving conditions. Again, the system is SPEED DENSITY, no MAF.

It is a hotrodders' dream. No complicated hookup.

Its got my attention. I could not find anything about the blowers. It did say it was compatible for superchargers and turbo applications, but I did not see anything about big blowers. I wander if you can run twins on a roots style blower? I will e-mail and see what they say.

...and is compatible with blow-through and draw-through supercharger and turbo applications.

Ask them about using two (TB) at the same time. Will the processor run them?

[302 Z28]

It sounds great if it does what it is advertised. Once it is out and people start using it we will know for sure. Granted it would be a dream come true for sure .

Saw a post on another forum that had the price at around $2000.

Looking at the wiring harness there are 8 connections.

The carb/EFI has 2 connectors (TPS & Fuel injectors). Some of the other connectors are for MAP, temp, WB O2, fuel pump. The other 2 may be for atmospheric pressure, maybe a VSS or knock sensor also?

[Arrowhead]

That's a pretty cool setup if it lives up to it's claims. I thought of it before (I'm sure many others have too) but don't have the resouces to build it.

Looks like they have a throttle postion sensor built into the throttle body and maybe that is also where they are getting the manifold air pressure reading, probably from the base of the unit (although that loocation wouldn't work for a typical blown motor). That helps keep it clean. You will have to install an o2 sensor in you exhaust though.

I like the idea of the pulse width modulation of the fuel pump, thats a pretty creative way of doing it, as long as the pump survives the variable speeds.

It will be interesting to see how they handle startup, acceleration, warmup as those conditions all require very rich mixtures which will be different for every motor as the 02 reading won't be much help under those conditions.

They should be able to capture atmosphiric pressure on startup, thats how megasquirt does it.

I still prefer the bugcatcher for my EFI

[kain13]

if it works it will be great id weight to see if it is all its cracked up to be before i spent 2 gs

Hotrodders EFI Dream Come True? we already have that its called megasquirt

yeah, megasquirt is great, but you need to know how to program just to get the tuning program to work with what series and version MS you have. cheap and deffinetly worth it if you can understand how to work everything
