New FAST EFI system
 

Just saw this in the magazine. Direct replacement for carb, does not require a laptop, and is supposed to retail for $1900 complete with everything needed. The other big difference is it will support a lot of power according to their ad, where similar systems usually peak at 450-500 hp max. Here's the info off their site:

FAST™ EZ-EFI™ Self Tuning Fuel Injection Delivers Easy Carb-To-EFI Conversion


New system features “self tuning” mode for simple and affordable plug & play installation

Fear not fuel injection fans. FAST™ has just made it easier than ever to convert your engine from carburetion to fuel injection with the new FAST™ EZ-EFI™ Self Tuning Fuel Injection System. The most important feature of this amazingly efficient system is the self-tuning operation that does not require chasing components, expert tuning experience or a laptop computer to tune. Simply hook it up, answer the basic set-up Wizard questions on the included hand-held display, and the system truly tunes itself. The FAST™ EZ-EFI™ Self Tuning Fuel Injection System is a totally complete system including the ECU, wide-band oxygen sensor, wiring harness, fuel injectors, fuel pump kit and other assorted components, including the innovative new 4150 Throttle Body from FAST™.

The FAST™ 4150 Throttle Body delivers the total package approach for anyone with an existing 4150-type intake manifold. Everything comes with the throttle body, including appropriate fuel injectors and fuel rails. In addition, it works with the original carb-style linkage and is ready to accept all OEM sensors. Available with injectors in four different flow rates to tune the system specifically for your engine, this well-engineered and high performance-intended product is a true plug & play system that will satisfy the requirements of FAST™ XFI™ engine controllers and all other major systems.

Yep, saw that a while back.

The manufacturers are really going after the "I want EFI but I'm scared of it" demographic, making things as "bolt in" as possible and even trying the whole self tuning thing...

Heck, even Professional Products is coming out with a throttle body "self tuning" kit. Knowing how PP stuff is... :_paranoid

Hopefully this whole push for the entry-level self tuning stuff gets the manufacturers to implement OEM-like block learn long term tables & routines into their ECU's and the more advanced aftermarket ECU's will benefit too.

I'm interested in this system. I'll have wait and see how people like it...

I'm curious if that will work with a blown application.

I am getting ready to either order the FAST or the Boss EFI. I am leaning towards the Boss EFI since it looks more like a carb than the FAST (I want stock looking carb but with EFI advantages), but I will buy whichever will have the better software after further research. This is the Boss EFI I am looking into but anodized black. The guys at Boss EFI state they can be used on blow thru blower applications.

pics I took at SEMA of the FAST setup.

Thanks for the pics Charley I completely missed it at SEMA...DOH. Do you all think it will really self tune? Since it's throttle body injected I would be a little nervous about getting a lean hole.

If this turn out to be the real deal I am all over it.

The look of the "Boss-EFI" throttle body is great. They are about five miles away, I will pay them a visit.

I would like to test one on my LS-3 (427) dyno mule engine. I have the GM "spider" intakes both EFI & carb.

My IGN8-1-H igntion will provide the spark.

Would there be an interest in the results

A tech over at fast said that the EZ Fast system will not work with boost.

Not what I wanted to hear :(

Is that ANY boost?
Blow thru, draw thru...
Maybe there is no reference for boost...

I asked about the weiand and magnacharger.

the new system uses alpha-N strategy.
it can not read boost (or vacuum)
it chases a targeted air/fuel ratio via wideband o2 sensor.

the new PP system looks an *awful* lot like retrotek's system...i suspect they're collaborating on producing it.

it wont work because this system uses a wide band to shoot for a set air fuel ratio target and then the computer continualy adjusts the numbers in the fuel table vs map ..

problem is thats no where near fast enough for blown aplications. and there is no boost reference to know what to do with the timing it simply is timing vs rpm just like a old fasioned ditributor

Is this system available yet? Has anybody had a chance to try it out?

Question for you guys
 

So, bear with me here guys, if someone has a carbuerted engine, they can convert with their system with the handheld device, swapping out some componets, such as the throttle body, fuel rails and such, and make it fuel injected?
WOW!!! Pretty impressive!:wow:

Except that you are still asking wet fuel to make it through the intake manifold evenly to eight cylinders with different length and configuration intake runner paths. The advantage of multiport fuel injection is that the only thing going through the intake manifold is air, with the fuel being injected right above the intake valve. If you're really looking for the advantages of EFI, I think multiport is still the way to go.

You also need to do a certain amount of plumbing and fuel tank modifications (EFI engines don't like interruptions in fuel supply).

I'm a big fan of EFI (have it on my SBC), but think that some of the "shortcuts" may compromise a little too much for not a big monetary savings.

Now a true self tuning multiport system? I'm all over that!

I guess my next question would be, would it still run properly with the "switch-over"? Sounds like you said about the EFI not liking the interruptions in fuel supply. Thanks for the info!!!:thumbsup:

EFI systems require much higher fuel pressures than carbs. LT1's (and the Holley Commander 950 that I use) like about 44 lbs, factory LSx's are up in the low 60's. In an EFI system, there's no fuel bowl as there is with a carb, so any interruption in fuel pressure is immediately felt in fuel starvation to the engine. Becuase they have the fuel bowl, carbed systems can tolerate the fuel supply pickup momentarily sucking air in a low fuel conditions, not so much with an EFI system. As a result, fuel tanks intended for EFI applications are at a minimum sumped, and should also be baffled to keep fuel around the fuel pickup at all times. In addition, because electric fuel pumps are noisy, most fuel tanks intended for EFI also have internal fuel pumps.

The best deal I've seen on a sumped, pumped EFI fuel tank is the Spectra tank: http://www.rockauto.com/catalog/cata...MIUM%2BGM32AFI. Although it's not specified, my guess (and that's all it is) is that the pump in this tank is of the 44 lb. variety.

I don't know if I answered your question.

We shot it at SEMA.. it's in the end part of this interview with Chris Douglas from Comp Cams.

Now I get it!!
 

Yes. You have answered my question. I understand now.
Thanks for taking the time to explain.:cheers: :cheers:
