my ds is cutting out

And take your quad "if you havent allready" to a dyno and let the tuner adjust your pc. Alot of the time most people dont understand what the pc3 or 5 can do with a proper tune.

some bikes with auto tune still need to be tuned? or dont they always work?

Im hoping thats what the problem has been with my Wienen quad all along! thats all i can figure! the back one wasnt getting any spark at all. Riemers21 hooked me up and i should have the parts thursday! so stoked! that 10 HP drop on my dyno curve at about 5400 rpm will be cured and that bike can finally start seeing more action. i'll keep you updated.

if there isnt a good base map installed the autotune will prob be off. its more of a "fine-tuning aid" so when you get into different elevations and air densities you are still at maximum operating efficieny, whereas a pc3 with no autotune will operate best during the same conditions in which it was tuned. the differences are small at best, but on a pro bike where every 1/4 hp counts, it makes a difference. it could be a bad tuner, or a bad tune, or a bad something else. gotta start with the easy stuff and work from there.

My Ds fire missing, balanced throttle by 6000-7000 rpm. Standard condition, but the pink wire were cut. A leaner mixture, throttle position sensor, the plugs? Air leaks was checked. After-market exhaust pipe were twitching worse. Where to find fault?
