2006 - 2012 Yamaha FZ-1 Page

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 FZ-1 (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 !! )

Our performance package for this bike includes: (you need to call for pricing)

Slip-on exhaust or Full Yoshimura exhaust system - Call for pricing.


Power Commander 3 or 5 (pre-programmed with Ivan's custom map)

Ignition module

FCEtm (fuel cut eliminator) FCE-001
Prevents the ECU from shutting off injectors during closed throttle decelleration and 10 hp more between 6000 and 9000 rpm.

Prevents the rough and jerky throttle response upon re-application from closed throttle, above 4500 rpm.
(PC3 or 5 and block-off plates cannot fix this annoyance)

AK-YAMR1R6 Block-off plate kit

BMC air filter

Also included with purchases from us:
Un-paralleled tech support
Instructions for setting up your PC3 orPC5 to your bike
Airbox modification instructions

Answers to all your questions.....

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

Just for comparision......

All stock vs. all above mods

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.
