I'll try to be brief. I made a post in the "general" section about my mpg's being lower than I would like (in the 30's consistently). I bought the '07 Custom a year ago used, and it came with V&H slashcut staggered pipes and FuelPak. I added a High Flow air filter.
The consensus from that post was to go back to stock air filter and remove fuelpak to gain back some mpg's. I called V&H tech support and they said instead of removing the fuelpak I could set modes 1-18 to zero, mode 23 to 30, then turn off the handlebar kill switch. Doing this takes the bike back to stock.
I did as they suggested, and took the bike out for a ride, and now the engine kind of sputters or hiccups, like it wants to die. It is only for a split second, and it is not happening constantly, just every so often. Needless to say, it bothers the heck out of me! So I put back in the old mapping, and the engine runs great, problem is gone.
What I'm wondering is if setting the fuelpak to "stock" is truly bypassing the fuelpak and only using the kawasaki ECU, or if it is just mimicking the stock processor. I'm tempted to remove it completely, but if the engine is going to have that hiccup, then I'll keep it on.
Has anyone else tried "turning off" the fuelpak and had any issues? Should I totally remove it? I'm not very confident in my mechanical skills, and I can't afford the $99/hr that the local shop would charge. I'd be willing to supply some beer or something if a local DFW friend could help me remove it!
