cutting out

[dirtymax811]

I have a 09 kfx 450r with dasa exhaust fuelatv intake and a pc 5. When i get on the throttle hard it seems to cut out and act like its not getting fuel. If i am easy on the throttle i have no problems. I am wondering if i need to change my map or do i have other issues? Im pretty lost!

It might be a map issue, but did you use the wire tap on the TPS for the PCV? If so, it might not be making a good connection b/c those taps cut through the wire.

Yes i used the wire tap. I checked that a couple times and im pretty sure it is making a good connection. I had it on the dyno twice and the guy that did it seems to think that it is a fuel injection problem. Just not sure if he didnt make the map correctly or do you still have to mess with the fuel injection? Thanks for your help.

I would guess it's a map issue, but I could be wrong. Check and see what your TPS voltage is. It needs to be around .62-.64 v. If it's not that could slightly cause the issue.

i know it sounds crazy, but mine will do that with 10% eth. gas, but not at all with pure pump gas.
