Yes i wondering whats the difference between the Dynojet Power Commander V and the Dynojet Power Commander V-pti?
I am going to be purchasing a power commander soon because i am adding a full exhaust to my ZX14.

The pti is for the supercharger/turbo induction systems. Yours is a normally aspirated engine.
The next question is year. Do I have an 02 system or not?
The way to know is to walk to the right side of the bike and look for the 02 sensor at the exhaust collector [where the 4 pipes enter into one] then look at that one big tube. If nothing is there, just the plain old V can be used.

Check into the PC5+Ignition. Ignition module and PC5 in one. Same case as the PC5 I presume so you are limited to 5 switch inputs if you want to use the full capability of the DJ system. If you get the PC5 and ignition module separately, you have switch inputs in both modules. If you are getting a flash and just using the PC to custom tune, you probably have no need to bother with ignition...unless you are going to use nitrous or turbo. My god that sounds awful confusing to use a PC on top of a flash.

The old PC5 has psi tuning for turbo but apparently not as good as the new pti module.
