haha true mark haha i could tell you guys some horror stories from some diy at home experts when try it, cant figure it out, and bring it to the dealer, and is like, "yeahi dont know what happened, this is how i found it"

 

I can only imagine.[:-]

 

probally voids the warrenty too right??

 

haha it would be the same as throwing a undertail on it, it doesnt throw a FI light but when we hook up KDIAG, it shows that the exhaust valve control system has been tampered with, and for how long its been down. If you go to your dealer please dont lie,

 

I didnt read the whole thread but i did the jumper mod and worked. use a short wire to jump between the yellow and black wire to...... i cant remember. look on zx6r forum. that is where i got the info. from. takes only a few minutes to do. but all it does is stop the exhaust servo from closing. when you add a aftermarket exshaust it is absolete. I THINK. I think i have my story straight. i put the yoshi rs5 on a couple nights ago.

 

The ECU Jumper Mod controlsFuel supply andthe Exhaust valve from signalsby the ECU. The Jumper Mod also affects the fuel at high RPMs so even if you get rid of the exhaust valve or install an aftermarket exhaust, the bike will still shut off fuel at top-end Rpm range. The engineers wouldn't design a system that would still dump fuel in with the exhaustvalve restricted. That would cause extra unburned fuel to ignitein the exhaust possibly causing a fire.It would greatly affect emissions and melt the Catalytic Converter.

There is a lot of mis-information out there on the internet &other forums.

So, Bottom Line: The ECU Jumper Mod affectsthe fuel supply andprevents closing ofor restrictionby the exhaust valve.

So even if you got a Slip-On or Full Exhaust, the fuel supply would be cutoff at Top-end rpm range. You will notice an improvement in power just because of the freer flow but not the maximum you can achieve without the ECU Jumper mod. One member here has already proven that on the dyno.


Please spread the word.

 

Black w/yellow tracer jump to green w/ light green tracer. Did mine the day I got it.

 

On a 07 ZX6R; The Black/ Yellow wire is a ground. Did you notice a difference after you did the mod?Black/Yellow to Green/Light Green is the correct wires to jumper.

 

so i don't really get it, is the mod a good thing or a bad thing?

 

It is a good thing; A VERY GOOD THING![8D] By doing the ECU jumper mod, you allow full use of the available power byremoving the restriction of the exhaust & fuel system. It's like Hot-Wiring the ECU.
