MAD EFI - Brucato PCU shoot out?

[TUG]

If i hadnt have found Wayne and his ecu, i was seriously thinking about puting carbs on my motor a while back !! I had nothing but problems out of Merc boxes !! Had a couple of good ones that never seemed to run right and eventualy went bad anyway, along with buying a couple that w erent no good when i got them either !! I have had it to my ears with Merc boxes and will never even consider buying one again !! If i wanted a new Merc box you can bet i would be calling Tony NOT MERC !! Ive even heard story's of people purchasing NEW Merc boxes and they being NO GOOD and guess what the waranty is on them NODDA!! Competition is good, always is !! Personaly i like Waynes SDS system !! I like being able to adjust while under load and also like the adjustability at every 250 rpm's !! For me Waynes is the chit, for somone else Tony's might be ideal !! Its all a matter of what you like folks!! BOTH ecu's "as Tony said" are leaps and bounds past anything Merc has to offer !! So when you compare Tony's price to a new MERC unit, its more than fair !! I will also say this, Waynes system ""to my surprise"" was way more than i thought i would get for $1175!! When i took it out the box i couldnt believe how much more was siting there then you get with a Merc unit for a couple hundred cheaper!! Also with the merc box you have to buy one dem Chopper City nini baby;s for 300 dollars just to see where your at when turning the fuelcurve up or down Add that to the cost of a Merc unit and see whatchu come up with !! Point is, they both better than whatchu got from Merc and can be used for anything from a fishing boat to a race boat for maximum performance !! Why you should buy one or the other is up to you !! I'm sure either ecu can tune your motor and give it what it needs ! I prefer tunability while driving, somone else might care less about that option!! Like Rex said, He likes Loony Tunes, i like Fruit Loops!! They'll both make the same turd though wont they?? cyu TUG
PS i would like to clear somthing up here!! Sombody said earlier in this thread that the MAD unit was desighned to work with the MAD intake well THAT IS NOT TRUE !! The MAD will work with a SVS just like the Brucato pcu will work with a MAD intake !! BOTH ecu's have a wide enough fuel range that they can be tuned to ANY aplication you want to run on Mercury and as for the MAD, it has enough to work on ANY engine, He even has a chip you can plug in the box for 12 injectors You can use the second 6 injectors to run Nitrous enrichment etc etc, !!THATS THE MIRACLE OF IT in the first place !! A programable ecu designed to work on 1 certain intake would kinda defeat the purpose in the first place wouldnt it? Anyways just wanted to clear that up for whoever said it !! cyu TUG

I have mad intake and sds it really works well.The only advantage I see to pcu is if you don"t port engine right you can turn up fuel 2 cyl"s across /instead of taking exhaust plate off and getting it right

[madman]

Sandbagger the bottom 2 cylinder are hotter and are getting super charged buy the upper two cylinder. So putting more fuel in those two would not help the problems with the exhaust track it would just help burn pistons quicker (MORE FUEL MORE HEAT IF YOU PUT ENOUGH FUEL TO COOL IT DOWN IT WILL SLOW YOU MOTOR DOWN) so what we do here is reduce the compression of the bottom two cylindersor with the MSD ignition we retard the timing.
I recived my first 220 Yamaha is 1986 they had the compression
decreasing as the cylinders went down. I fix that with a new set of heads and burnt a piston on # 6 recut the stock and left the compression lower on the bottom two and had no problems.
Yamaha tought me that I will never forget it and I will alway cut heads with the bottom two with less compression even at 220 lbs of compression.
Mercury v6 is two 3 cylinder side by side, so you have to tune bank to bank, if you want the most hp and the best idle you would need to contol the fuel for bank to bank not batch pairs like Mercury does.
If you have a horn motor Total Contoll will let you tune bank to
bank and we run 28% less fuel on 2,4 & 6 . This the only ECU
that will do this.
Why buy all those gauges on the dash and not have one gauge that let you see what your efi is doing not one.
Total Control
Will let you see
Engine temp
Air temp
tps angle
RPMS
fuel curve every 300 and the fuel number
and a lot more !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
but you can see what you are doing
There are a lot of parts to a EFI system and you are getting a complete system not just a box that is why you have to install it
but it is not like you are going to have to do it every day or so.
No ecu failures in the past 4 years
I you would want to ask me any ?????

It must be nice to have one of
these defending your product.

You can go back to sleep now.

Wayne, do you really run 28% less fuel on 2,4, & 6 ?

I'm not being a smart ass, but why would that be? Are you talking about at idle only, or at higher operating RPM ?
Is that necessary on just the horn motor with crankcase injection, or on Laser style injection too?

I was very happy with the SDS that I bought from you for my ProMax motor, but above idle speed I saw no difference in performance by adjusting bank to bank. That was just my experience and I wouldn't doubt that others experienced different results.

I have however, seen performance and reliability improvements by properly adjusting the injectors as pairs. This has been particularly true on crankcase injected motors.

Tony Idle only and 2,4,6
They do like +1-2% more on top if you realy get to turning the up over 10000 RPMS.
I did pairs when I start writing the software and had egts in every
cylinder and found the banks were the biggest need for bank to bank in my test .
I think we both have a good products and we both will help body in any way so what we find is what we find and that is the reason we build what we build and how we configure it.

[Tony Brucato]

That's right Wayne.
We both know that our own way is not the only way.

I think that either of these adjustable ECU's is a vast improvement for somebody trying to get all the HP out of their motor.

[David P.]

I just got a PCU and haven't had a chance to really run it yet,
but I'm confident I'll be very happy with it. I'm sure Wayne's
is also a great unit.

The point I would like to make here, is the professionalism, and honesty of both Tony and Wayne. With all the crap going on
in this world, it really makes me feel good to see two gentlemen
that I know feal strongly about their product, who have spent
a great deal of time in research and developement have great a
deal of respect for each other and their products.
This is what I call class.

Hi Madman and Tony,

Would it be possible to use a MAD ECU system on a PM 300 with a SVS Intake and High Flow Reed Plate as a substitute for Rapairs ECU work? Pls advise.

Cheeeers, Toffen G

[madman]

We have a curve for a 1999PM and we did get Rapair to Help with the Ignition boxes pick up 200 RPM because of there work!!!!!
You would need to work the reed blocks, then hold ON you let more air in with SVS but the reeds were not changed and one reason the newer 300 run better are the reeds and block they use.
Yes the two would work together.

[mjwalters]

Why is it not possible to use the stock ECU with larger injectors or raise the fuel pressure? That what is sometime done with a IO motor

[madman]

Sometime that works on stock motor without mods but you when go and change the intake system,tuner and heads or reeds it doesn't fix the problem.
When running a higher fuel pressure the idle goes away quick
with a few pounds of fuel pressure changes.
Fuel curve follow the prop if you have rich box put on a larger prop and the rich curve just got better because the demand for more fuel of the larger prop. If you have a lean box try smaller prop. If you put a larger intake on and better reed block on the motor the ecu went lean becuse of more air. Then some people
would take the intake off because it slow down because of the lean condition cause by the amount of air per rpm.
IO run a flater fuel cuve than a 2 stroke and will hardly ever 4 stroke becuse of a rich condition they will just burn it.
