FAST Programmable EFI
 

The last few weeks I have been playing around at the shop with the new FAST EZ EFI 2.0. I don't believe it can get any easier then this. It comes with a little tablet and you just need to answer a few questions.

This is a direct carb replacement. Everything comes with it, fuel pump, regulator, gauge, filter hoses and hardware. This is the 1200HP kit that has 8 injectors in it and will flow ~1050cfm. JimV (Valako) just installed a pair on a set of 540's he just built.

I think I might be going to EFI soon.

I've heard of guys using the FAST EFI on drag cars around here, never thought about a boat application. Sounds nice!!

I think they require 02's and there may be the issue..

It has O2's installed. We actually ran it for 30 mins with the silent choice shut with no issues. I believe once you are satisfied with the automatic learning you can turn it off and it will use the last stored fuel, load, TPS etc data. I'm still just learning this. When Jim and I were at the PRI show I believe they spoke of this.

The cams are relatively mild making around 700HP.

Keep the 02s dry and they will work for a long time.

that is easier said than done with some exhaust...

It looks like a pretty nice setup. I have read other post about programming it and it seems like you give it some parameters and it self tunes. I can't really tell where the injectors are with your pictures. Are they in each intake runner or?

they are in behind the covers that say fast.

Is this a returnless fuel system? It looks like I see two inlets unless one is the feed and one is the return.

FAST put 4 injectors where the float bowls on a carburetor would be located. They are 4150 style flanges.

They can be ran with return or return-less. They recommend with a return. This is also setup with the exterior fuel pump you can also get an in tank fuel pump.

Haven't had a problem since 1997 when we started running them.

So where are the o2 sensors?

In the headers, kept them a little closer to the block,

You can see the the O2 on the port engine top outside pipe in the front. The starboard engine black plug inside tail pipe in the front.

This looks really cool!! Do you you only run one 02 sensor in each motor? Looks like the other tail does not have a sensor in it. Also for us roots style blower guys, could you get away with only one throttle body on top of a 10-71? Right now I run twin 850 Holley's on top of my 10-71's but if each throttle body will support 1200hp that would be plenty. I too would love to go EFI!!

you only need one to get tune in, just some exhaust keeps getting the wet and kills them quick, lightnings for sure, plenty of talk about that on here...

I just called Fast and they said this quick learn system does not work with any power adders, but there XFI system will. However the XFI system will still require tuning and programming, not a self tuning system...

i have been looking into this for months and i am dead set on doing this EFI setup. i have a older holley MPI kit that i have everything to make it run but i don't want to deal with programming the old school commander 950 computer. i have not found allot of feedback on them but i have found actual marine engine companies selling their brand new warnateed engines with them so they have to be working well. the bad comments i have seen are from people that have tried putting them on engines that are beyond a basic self tune setup. i am planning a 496 stroker with aluminum edelbrock heads, hoping for 550-600hp. i am running gil HP500 style tall manifolds and risers so i don't believe that i will have too much of a issue with keeping the O2s dry. good post!

I contacted Fast awhile back about their self learning systems and the thing that killed my application is that they need to see 9" of vacuum in gear to tune properly. My cam is too big I barely pull 9 in neutral. FWIW

What is your initial timing set at? It is my understanding that going to a module that allows you to run more initial timing may help it to idle better in gear and it may boost your vacuum signal. A lot of guys with big cams and blowers, etc., have gone to the V6 module, which allows you to run 20*+ at idle.

from what I understand, many have a self tune deal now, which work for milder engine setups, boosted, and more radical ones will require some tuning on your own...but that's not that bad one unit is close...

I'm locked at 34, I've tried several custom bushings in my MSD distributor and it runs best overall locked at 34. My cam bleeds off enough compression at low rpm that I don't get preignition when getting on plane. I just get the engine cranking before I bump the throttle although once it's warmed up it fires instantly.

What was the total cost per motor for this swap, Rookie?

The complete kits with fuel pumps, harnesses, throttle bodies and computers. I believe were around $2400ea then add on labor for rigging; return lines, wiring, welding O2 bungs etc...

Ouch!

So that, plus heads and intake would turn a mild MPI 509 into a pretty smooth operator for not a lot of coin.

Definitely, a Dart single plane, pair of Dart heads, Jims cam and the FAST EFI setup. Pretty simplistic smooth setup.

Lol, if I wasn't on the fence about if I am going to put my blowers on our not I'd probably already have these setups. I agree that it is some decent coin, but for NA systems it's the least expensive complete bolt on setup there is out there.

FAST told me they do t reccomend their system for a marine application. Any issues other than mounting the O2?

Are you talking about this http://www.ebay.com/itm/Fast-Xfi-2-0...3bd839&vxp=mtr

Rookie is there a way I can get a hold of you. I have some info to pass on to you. That's it, nothing pressing or bad.

Yes, I tried to PM you, but your in box is full.
