Power Commander
Hello
New to this forum but not to bikeland or sportbikes. I have a coworker who is big into sportbikes but very limited in aftermarket knowledge. I told him I would see what the guys on the bikeland website would say to his delemma. Question is, can you take a stock ZX14 and just add a power commander to change the bikes mapping to give it more bottom end ? will a power commander alone do this just fine without having any negative effect on the bike other then the loss of some top end. Friend has been a big Hyabusa fan for years and has owned many but has fell in love with the 14 but would like to know if the power commander will do what he would like it do before jumping in to a purchase.
cheers and thanks

It will help a bit low down, but nothing like removing the sub-throttles.....top end could be increased as well. Factory tuning is pretty good except for where emission tests are done.

Sub throttles ?

Could you explain a bit about how you would adjust the bike for low end by just the means of a power commander and these " sub throttles "....
Cheers

I think he is referring to the secondary throttle butterfly's. There are two sets of butterfly's in each inlet tract. One set controlled by the throttle twistgrip and the second by the bikes ECU. This second set keep the throttle opening small in various pre-mapped situations, such as rpm and gear ratio, this is what stifles the low-end power.
It's quite a popular modification to remove these and re-map the fuel injection via a Power Commander. Some folk claim that re-mapping is not needed, just removal. There's a whole heap of posts on this forum on the subject.

Just adding the power commander will make a change but it will not be very noticable. You should really consider removing the secondary butterflies. It's easy to do and not very expensive to have done. You will notice a drastic change as soon as you hit the throttle.

Yeah, I got talked into doing this mod and I LOVE IT! You can't beat free power, and you gain lots of it on the lowend. It's like night and day difference, no joke!

I got about an extra 20+RWTQ where the dip used to be...........there is more power at almost every point, but it is most noticable at cruise RPM's.

it is extremely easy to do ... get a long magnetized no2 phillips screwdriver lift the gas tank and take off the two aluminum covers that open into the airbox the first thing you will see will be 4 black velocity stacks and inside 4 mettalic disc with two screws on each first make sure YOU DO NOT TOUCH THE THROTTLE WHILE DOING this, then take the screw driver place it firmly n any of the screws give the top of the screwdriver a good 5 good solid TAPS witha hammer then with constant down pressure loosen the screws slowely eight screws and 20 minutes later TELL YOUR FRIEND TO HANG ON!!!!! Good Luck

After a couple of months of sitting on the fence, my 'flies will be coming out next weekend.
I've read somewhere that our UK bikes tend to run richer over here anyway due to the different petrol we use so I am hoping I won't need to fit a PC3.
I will be taking the bike up to a guy near Brands Hatch who has a Dyno shop and really knows his stuff, and I will ask him to pay special attention to my A/F ratios.
Will report back what he says (if I don't melt it on the way up there!!)
