I am pleased to announce that I have successfully re-programmed the stock FZ1 ECU to my own exacting specifications as listed below.

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-

Our 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

See Dyno Charts Below

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

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 remain.

(Fuel Cut is a federal emissions regulation requirement for all EFI vehicles sold in the USA since 1980...... NO VEHICLES ARE EXEMPT !! )



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
