Go Wings!
It was raised in another thread there was an ECU reflash available to apply some fixes to various issues. One such company is ECUunleashed who seems to have a dealer network, and another potential is Ivan's Performance. My specific interest is in eliminating the throttle snatch caused by the fuel injection cutoff when you roll off, and the cut-in when you reapply throttle, particularly annoying in the middle of that nice twisty turn you're in the middle of. So I am now intrigued to discover this ECU reflash idea, or if there is a fuel cutoff eliminator. I am not particularly interested in all the mod items they list, and would like to preserve or minimize the penalty to fuel economy.
Many also have attempted to fix various FI issues by remapping with a PC3 or PC5, Barbarian mods and such. I'm also wondering if anyone has a PC map suggestion to fix/partially fix the cutoff issue. There was an interesting map posted up that added +25 at the zero throttle position (albeit at higher rpms than I was expecting)..... wondering if that had a positive effect, or if anyone has experimented with mapping at zero-low throttle positions. See post #11..... https://www.fjrforum.com/forum//index.php/topic/155092-looking-for-pciii-maps/

Ivan's Performance site and info from the FCE page (and copied below) - https://www.ivansperformanceproducts.com/fce.htm
Ivan's has an FCE for the Honda ST but nothing listed for the FJR. I'll have to give them a call.
Also wondering what all this costs....... anybody done an ECU reflash??
Appreciate if some knowledgeable individuals can post up some insights............
What is"fuel cut" ??
(Fuel Cut is a federal emissions regulation requirement for all EFI vehicles sold in the USA since 1980...... NO VEHICLES ARE EXEMPT !! ) "Fuel cut" happens when you close the throttle anytime above a preset rpm, in other words the injectors will stop.....
On the FZ-1 it is anything above 4500 rpm
ST1300 is 2500 rpm
Z1000 is 3600 rpm 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 or trying to manuver the bike at low speeds.
This can also be heard with an aftermarket exhaust as a loud pop/bang/flame when the injectors come back on Under these conditions, throttle response is much less than precise. I have designed the FCEtm for these bikes, and as a result there is a very marked difference as to how much better these bikes respond and behave under any riding condition.... Using this product, this bike is transformed to a perfectly smooth and predictable ride under any riding condition, and the rider can pay more attention to where he/she is going rather than how carerfully the unpredictable throttle is re-applied.
