Bike won't accelerate during roll-on
 

I'm stumped!

Bike runs great at cruise and normal acceleration, but if I roll-on to pass, etc....it won't take the gas....starts sputtering, popping, bucking...sometimes it will clear and go, but most times it just won't accelerate unless I back off and increase throttle slowly.

My build is below....I've talked to Zipper's at length and we don't think it's a TMax AT/sensor/map problem. Plugs are new...new fuel filter and internal hose.

Starts and idles and generally runs great....just won't roll-on.

HELP!

Problem solved.....I took the TMax off this morning and reinstalled my old ECM and PCIII....bike runs great and will roll-on with no problem....looks like I'll be getting a new TMax module!
