I am pleased to announce that I have successfully
re-programmed the stock FZ1 ECU to my own exacting specifications as listed
This is the best result in driveability and power
anywhere for this model - our proprietary software guarantees it !!
My programming for this model will blow away
ANY ECU flash from any other company in both driveability and performance
My FZ1 ECU programming (Re-Flash) includes the following:
1) Low gear power limiter removal
2) All driveability inhibitors/limiters removed
3) Disable fuel cut
Our proprietary software/hardware is the only one that is capable of disabling
this annoyance in
all the places/conditions that it exists !!
a) Gets rid of
poor throttle transitions from closed throttle.
b) Gets rid of annoying popping and banging during decel and also jerky
response when re-applying the throttle from closed.
c) Throttle modulation is noticably improved over what can be achieved
with a fuel tuner alone.
d) Dramatic improvement upon re-application from closed throttle
(in all riding conditions).
4) Re-program sub-throttles for max power and response at any rpm
and throttle position
5) Cooling fans come on at 200 degrees
6) Complete re-curve of ignition timing at all throttle positions - optimized
for 89 octane fuel
(premium fuel not necessary)
7) Raise rev-limit to 12,300 rpm
8) Reduced engine braking during decel
9) Anything that compromises performance and/or driveability is eliminated.
10) EXUP code removal - No servo eliminator needed !!
- Done without disabling the rest of the bike's self diagnosis -
-Your bike will still display trouble codes if a problem arises just like
it does now-
proprietary software/hardware keeps your bike's self diagnosis 100% intact
Requires PC3, PC5, or PCFC - (not included)
All testing was done in house on my personal FZ-1
Dyno tuning not necessary
We can reprogram for the following markets:
USA, Australia, Europe

Stock ECU Vs. Ivan's
All mods the same (full yosh, a/b mod, BMC filter PC5 w/mapping) No FCE,
Same day test
The Yoshimura full system was designed to work
with all of my modifications...
and was subject to my approval before being released for sale.
Yosh full system vs. slip-on
w/ gutted catalyst -
both with proper mapping.
Same day test.... back to back within 1/2
The Old Stuff - Obsolete
This bike has lazy throttle response,
and also the typical abrupt on/off throttle transition problem that all
of todays EFI bikes have.
This is due to "fuel cut".....
"Fuel cut" happens when you close the throttle anytime above
4500 rpm (on this bike), the fuel injectors will stop.....
Upon re-application of the throttle, there is a delay before the system
will start back up and re-wet the intake tract and combustion chamber.....
the rider feels this as a delay and jerky response from closed throttle....
especially while leaned over in a turn.
In addition to the response problem, there is also one loud bang from
out the exhaust that is usually heard when re-applying the throttle, after
you change the exhaust.
Under these conditions, throttle response is much less than precise.
I have designed the
FCEtm (fuel cut eliminator - $195.00) for this bike, and as a result there
is a marked difference as to how much better this bike responds under
any riding condition.... and as the first dyno chart shows, more midrange
power between 6000 & 9000 rpm.
The product will add as much as 10hp due to the sub-throttles opening
at a faster rate as well as preventing the EFI system from shutting off
under decel conditions.
Combined with proper fuel and ignition mapping, this bike is transformed
from a precarious ride under aggressive riding conditions to a perfectly
smooth and predictable ride under any riding condition.
This product will make a marked improvement in any
year fuel injected Yamaha FZ1 (2006 - 2013) because it eliminates
the root cause of the abrupt throttle response - "Fuel Cut"
and it also offers the advantage of a faster opening rate of the sub-throttles....
regardless of what the factory may have done to improve this model.
The fact is... as long as there is "fuel cut", the problem will
Cut is a federal emissions regulation requirement for all EFI vehicles
sold in the USA since 1980...... NO VEHICLES ARE EXEMPT !! )
Stock 2006 FZ-1 vs. Same with Ivan's FCEtm
a slip-on exhaust with the FCEtm and PC3 with proper mapping will wake
this bike up considerably....
stock w/FCE vs. Slip-on exhaust and FCEtm, PC3 w/Ivan's mapping
an ignition module will sharpen part throttle response as well as add
some power to full throttle.... in addition the bike will run noticably
cooler and will return better fuel economy.
exhaust and FCEtm, PC3 w/Ivan's mapping vs.
Same with ignition module
the airbox and adding a race type air filter will yield improvements starting
at 4200 rpm with the proper fuel map.
exhaust and FCEtm, PC3 & IM w/Ivan's mapping vs.
Same w/airbox mod and race filter.
not satisfied with the throttle response, and wanting the bike to feel
like an instantly responding 1000cc bike (like it should be), I designed
these new replacement sub-throttle plates.... These plates will put back
the response that you are after.... more power at any throttle opening
and dramatically better response at part-throttle.
of the above mods vs. same with our sub-throttle plates - Obsolete
stock vs. all above mods
