Yamaha SHO ECU flashing

i'll be doing ECU flashes here at the shop.
as most know, i'm a NIZPRO Super Charger dealer and installer.

well.. nizpro has written a nice powerful ecu program for those that don't want
the supercharger.

cost is 640.00 and i do them right here in my shop.

pm me here or email me at info@hydrodynamics-usa.com

i should be licensed in the next day or two.

thanks
Steve.

if you wish to have this done.
please make a call or email or message to me with your
model number and serial number of engine.
i'll need 48 hrs to setup the appointment and do the flash here

How does this effect the warranty?

if you stay with the stock limiter, it won't effect it.

if you choose the 7k limiter and run it there... it'll show up if they ever pull the
max rpms off the computer if you have an issue.

Whats the benefit?

more horsepower and torque through out the midrange.
better hole shots
much better midrange power
and of course ... a mph increase.. usually requiring a new
prop of around 2 degrees higher pitch. 7-12 mph increase.

and a high percentage of the time the fuel economy improves as well
as the tune is very effecient.

Makes 310 hp at 6950

with the 6400 limiter it's 298-300 hp at 6400

If speed isn't an issue, should I just stay with my std 250 on an FX21?

Yes

if you fish tournaments it could get dicey on a polygraph if you really want to go fast in a boat why nit get a Allison or bullit .

your the only one that can answer that.


as far as "other" benefits. more available power from an ecu flash means

1) quicker hole shots, reducing fuel consumption
2) quicker and more power at mid range means a tad higher speed at that mid range
3) of course top end is there when or if you want it.

both ecu flashes are now licensed and available

6400 limiter
7000 limiter

call for details and scheduling.

thanks

I have a std 25T1 prop. Need to change? How long to do it?

depending on how many rpms you currently turn, you may need to go up 1 to 2 degrees in prop pitch.

once i get the serial # and model # to nizpro to verify the current program (which can take 1 to 2 days)

in house it'll only take me about 30 minutes to do.

Right at 5600

at only 5600 rpms now, you may only need one of the following

1) a new prop with 1 degree higher pitch
2) have your current prop worked up in pitch (which will be cheaper)

your a good candidate for this flash.

TTT

can a 225 SHO be flashed?

YES.. the 200, 225 and 250 all use the same flash..

any of them can be flashed with your choice of the 6400 rev limit or the 7k rev limit.
