    Default FAST efi

    I was just wondering if anyone could give me some feedback on the FAST efi plate system. I have a bug catcher at the moment and just thought it might be a better way to keep a good tune up for a lake boat. All experiences are welcome and appreciated.

    Which plate system are you asking about? There are several available out there as well as throttle bodies with injectors in them. I have tested all of them on the dyno with FAST.

    Part# 30-113010. A guy has one for sale used and it just got my gears turning. Of course the mfi isn't necessarily ideal for cruising the lake so I thought this might be the best compromise for form/function. I just think carbs are ugly.

    TurboNova, if you have any suggestions, I'm all ears.

    Part# 30-113010 is not a good part number. But looks to be a EZ system. I have put a few EZ EFI series 1 ecus on boats, they are not quite my favorite setups. I have had some issues in cars but in a boat they have worked ok. The new EZ EFI 2 is 10x better than the older system and has timing control, both are self learning systems so you have to have a good place for the O2 sensor to connect to your exhaust. We have put together our own kits with the FAST XFI ecu and one or two throttle bodies. One throttle body for the carb style intakes or two for a blower, this has worked out real well giving us the adjustability of the better computer and the nice throttle body and working with boost. There is also the option of using the new EZ 2 ecu on an older Merc 500 or 525 intake and use all the stock Merc sensors, throttle body and injectors with an upgraded ecu, this does require either a FAST distributor or MSD. Neither of the self learning ecus works with boost and are not programmable with a laptop. Let me know what you are looking at exactly and I can give you some better feed back there are lots of options. You can also see all of this stuff at www.theefistore.com under fuel injection>efi kits.

    Neither one works with boost and the EZ EFI ecu but you can use either throttle body and XFI then it will read boost.

    Sorry about the #, it was just what was in his for sale ad.

    Going on a .030 over 454 with a 6-71 on gas in a flatbottom. I don't really mind the mfi but one day it's lean and the next it's fat so I always have to keep an eye on it. Thought this might be easier/better for my use. What is my best route?

    Bless your heart! TurboNova will direct you well. Just when I think I have my EFI units tuned well, he comes up with some more info from dyno runs and new EFI projects. Since you have a blower, you might look at RootzEFI: Home -

    Thanks fellas! I like the theory and advantages but it might be best for my simple mind to stick with my mfi and mag. I'm not much on computers anyway and that's the last thing I want to have to take to the lake. I just saw what appeared to be a ready to run set up for sale and thought for the money it might work better for my situation. Glad I asked some questions. Thanks again guys!!!

    The system the OP is talking about is a 6 nozzle plate system that fits under a Enderle or Hilborn hat driven by a FAST ECU.
    Its probably an earlier unit because the newer Hilborns blower EFI units are using FAST XFI controllers.

    With only 6 injerctors they tend to be a little power limited unless you want to get into some jumbo injectors. But probably fine for a pump gas lake boat.

    EFI and ready to run are two things that should not be in the same sentence. There is no such thing as EZ plug in and it will work 100%, it takes time to dial them in no matter what brand, type or system.... just like a carb. It is more precise, tunable and a better running deal in my opinion but also takes patience and proper wiring ect.. to get the end result you are looking for. There is a lot of junk out there and stuff that plain does not work, lots of claims in the industry that is plain not true, separating fact from fiction is half the challenge.
