    Default recommended efi for aluminum 632 with psi screw blower

    got a buddy thats sick of dealing with issues he's been having with his 1450's doesn't really want to idle and stalls when coming in to dock or trailer.
    wants to know who's got the best efi set up for his combo and if there's a second best thats much cheaper as well.
    oh yeah motor is in a 27' conquest deck boat if that helps any

    Let's see... he has an aluminum 632 with a PSI... now he wants to save money on an EFI, did he also put cheap 1450's on it?
    Did he have anyone that knows anything about engines set up a dstributor? Is it locked out?

    yes "he sure does"
    yes "who doesn't want to get the most bang for their buck regardless of how much they have in the bank?"
    no "they are boost referenced holleys that work better on the billet 1450 but still stalls some times as well but he wants to put the psi back on"
    yes "he's had a couple people work on it with the same result"

    did you have the answer to my question ????

    who makes THE BEST EFI and if there's one that works just as good and will save a grand or three can some one point him in the right direction of that one? THANKS!

    It's been a few years since I've researched all the details and differences, but I've heard good things about FAST EFI. They recently came out with a marine version too.

    If saving a buck was my #2 requirement behind performance... MegaSquirt seems to offer most, if not all, of the tune-ability and performance as the high dollar units. The down side is it's a REAL DIY type of solution.

    ZERO first hand experience with either.

    Wish I had an all aluminum 632 with EFI and a PSI

    Good luck to your buddy!

    There is a marine engine shop in FL that does EFI and PSI blowers. Don't remember their name.

    If he can't do it himself he is probably out of luck.

    seems that fast efi systems are designed for under 1000 HP he is way beyond that.

    FAST systems can handle any HP you can throw at them as well as BigStuff 3 and Holley Dominator EFI systems. I will be putting a Holley system on my TT 19' Schiada GN next week, sick of the fuckin' carb bullshit also. I have BS 3 system for the 621 TT motor but may change to a Holley system if this first one works out. Each system is good but what you choose also depends on who is going to do the initial tune if you aren't comfortable doing it yourself!

    The only guy I know with FI experience and PSI experience that could pull this off is Alexi (or his crew) at Boostpower.

    My experience with the Alexi is as follows.

    1. Listen to what Alexi says you need.
    2. Do it. (usually means pay him to install and tune it.)
    3. Enjoy. (while following the instructions you were given on care and feeding.)

    Anyone who made that statement is ignorant of how EFI works.
    Basically all EFI does is fires injectors , it doesn't know if the system is on a boat, a car, or a jet ski. The only HP limitation would be related to the size injectors or throttle bodies you are using.

    There are many ECU's that would do a fine job including FAST, BS3, Haltech, Motec, Electromotive, and many more.
    How the engine runs is totally dependant on the programming ablilites of the tuner.

    The ONLY limitation I have ever heard of, is maxing out a VE table. In that case, you tweak the injector constant a little (and re-tune), problem fixed.

    Lol! Like unchained mentioned. Any system can work if the tuner knows what's up. Some have better resolution/or control ability per say.
    We have maps for every system known for just about every marine/auto engine. We can also convert maps from one system to others.
    Anyway, they all pulse from say 1% duty cycle to say 80% duty cycle, however I would not recommend pulsing any injector much over that. It will overload the injector driver and cost you $$$$$$$$$😜
