My FZ1 ECU programming (Re-Flash) includes the
1) Fix all fueling problems inside the ECU.
(The ones that cannot be fixed with
an external fuel tuner or other commercially available methods)
All gear dependent fuel maps fixed.
Main fuel tables (A/n) - adjusted in all active throttle positions.
Vacuum tables (MAP)- adjusted in all active areas.
Emissions compliant sub-routines that affect driveability - turned
All system response delays (detuning items) - turned off.
Acceleration enrichment thoroughly tested and re-adjusted for correct
response with new sub-throttle settings.
Optimize injector timing for best power, response, mileage and
O2 sensor disabled - No need to unplug, or can be removed if desired.
Close AIS valve in flash - no need for block-off plates !!
EXUP code - no need for servo eliminator !!
fuel tuner not needed - just plug in and go !!
2) Disable fuel cut - ie; Jerky throttle -
Don't know what "fuel
cut" is? -
Fuel Cut demonstration videos here:
Live datalog https://www.youtube.com/watch?v=wgBznc8yXJc

Engine stays running when the
throttle is closed.
With stock ECU programming, the injectors are not running
when you decel.
(please see the demonstration videos above)
Gets rid of poor, imprecise throttle transitions from closed throttle.
Eliminates all feelings of driveline lash and jerky, delayed throttle
Changing gears is dramatically improved. Without fuel cut disabled,
there is no "neutral throttle"
This is the direct cause of your touchy, jerky throttle because
the engine isn't running during decel.
Dramatic improvement upon re-application from closed throttle in
all riding conditions.
(Throttle re-application response feels like our old carbureted
bikes used to feel)
No need for a different throttle tube ratio to try to prevent jerky
(which it cannot do anyway)
Gets rid of annoying popping
and banging when re-applying the throttle from closed.
3) Close AIS valve electronically
No need for block-off plates for air injection system
No popping on decel !!
No hoses to plug - Just plug in your ECU and go !!
Cooling Fan comes on at 195 degrees and goes off at 186
Helps keep engine cooler when you are stuck in traffic.
5) Reprogram sub throttles for
best response and to remove power restrictions
This allows a more sensitive throttle
that is easy to control.
Allows all of the FZ1 engine's available power - whenever you ask
Gives immediate engine response to the throttle with no restrictions.
Low rpm power is dramatically improved, while preserving fuel economy.
Response delay filters turned off - part of original detuning
6 ) Complete custom re-curve of ignition timing
Set main timing tables for maximium
power and driveability across the entire rpm range and all throttle positions.
This also helps provide better fuel economy, and less
vibration when cruising and moderate acceleration.
All gear dependent maps equalized and adjusted for best power and
All emissions compliant / gear dependent detuning sub-routines
7) Raise rev-limiter to 12,300
Raising the rev-limiter on this engine (700 rpm) up to 12,300
rpm allows the power to continue with my ecu programming.
Reduced heavy engine braking on decel.
More relaxed gear
changes and throttle modulation at all speeds.
Chassis is more stable because bike doesn't pitch back and forth
suspension when throttle is closed and re-applied.
More stability when entering a turn.
Slowing down is relaxed and natural feeling... Not like you just
9) Improved fuel economy
10) Reduced running temperatures
Coolant temps average appx
25 degrees cooler than with stock programming
Dramatic reduction of heat flow from radiator that cooks you while
riding in traffic
11) All power limiters removed
12) All driveability inhibitors removed
FZ1 engine revs instantly, and offers fantastic fuel economy too !!
13) Free updates when/if we make improvements.
(shipping not included)
14) Return your ecu back to stock at no charge for any reason.
(shipping not included)
Anything that compromises performance and/or driveability is eliminated.
External fuel tuner not needed - just plug in and go !!
All testing and tuning was done in house on my personal
Yamaha FZ1 shown above !!
not necessary !!
We reprogram for USA and Canada !!
reprogramming may not comply with federal safety/emission laws !!
ECU reprogramming may not comply with your warranty !!
dyno charts coming soon !!
Old ECU flash w/power commander
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
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
