My FZ1 ECU programming (Re-Flash) includes the following:

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 off.
• 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 combustion efficiency.
• O2 sensor disabled - No need to unplug, or can be removed if desired.
• Close AIS valve in flash - no need for block-off plates !!
Disable EXUP code - no need for servo eliminator !!

External fuel tuner not needed - just plug in and go !!

2) Disable fuel cut - ie; Jerky throttle - (ours exclusively)

Don't know what "fuel cut" is?

Fuel Cut demonstration videos here:

Live datalog

Live datalog Disabled:

• 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 response.

• 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 response.
  (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 !!

4) 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 for it.

• 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 fuel economy.

• All emissions compliant / gear dependent detuning sub-routines turned off.

7) Raise rev-limiter to 12,300 rpm

• Raising the rev-limiter on this engine (700 rpm) up to 12,300 rpm allows the power to continue with my ecu programming.

8) 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 on it's
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 hit
the brakes.

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)

15) 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 !!

Dyno tuning not necessary !!

We reprogram for USA and Canada !!

ECU reprogramming may not comply with federal safety/emission laws !!
ECU reprogramming may not comply with your warranty !!

New dyno charts coming soon !!

Old ECU flash w/power commander
(now obsolete)

Stock ECU Vs. Ivan's ECU programming
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 hour.


The Old Stuff - Obsolete

All Stock 2006 FZ-1 vs. Same with Ivan's FCEtm


Adding a slip-on exhaust with the FCEtm and PC3 with proper mapping will wake this bike up considerably....

All stock w/FCE vs. Slip-on exhaust and FCEtm, PC3 w/Ivan's mapping

Adding 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.

Slip-on exhaust and FCEtm, PC3 w/Ivan's mapping vs.
Same with ignition module

Modifying the airbox and adding a race type air filter will yield improvements starting at 4200 rpm with the proper fuel map.

Slip-on exhaust and FCEtm, PC3 & IM w/Ivan's mapping vs.
Same w/airbox mod and race filter.


Still 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.

All of the above mods vs. same with our sub-throttle plates - Obsolete


Just for comparision......

All stock vs. all above mods
