can it pass an inspection? just wondering

Even stock there's a lot of room for improvement. I guess you've gotta ride a well tuned XB to know what you're missing. Exhaust tuning is a science in and of itself. The factory has the EPA to deal with in terms of design and fueling and thus is compromised. The dyno may only show a few HP gained, but the throttle response and midrange will have a huge improvement that can't be quantified by numbers alone. If you're good with how it runs, so be it. I just don't like settling for that.

a pipe does nothing more than MUFFLE exhaust noise. fibreglass, chambers or baffles in a pipe mainly serve the purpose to quiet down exhaust pulses. yes some backpressure is lost, but not so wild that a stock ecm cant compensate for. most exhaust mods will barely even show an increase in hp or torque so why would you need to "TUNE" your ecm. my buell runs TITS with my almost-free-pipe and stock ecm.

haha, the "operator" is my retarted brother, he rides it like he stole it. but really hes an idiot.

Most non-trained enthusiasts will do more bad than good tuning with ECM Spy by feel...especially if they think gutting their muffler doesn't affect anything...same as all the folks who who've been screwing up their carbs before fuel injection.

What it does is called remapping...as you're adjusting the fuel map of the stock ECM. I've gutted a muffler for a friend. You can use the stock map if you don't mind a midrange lean spot and the corresponding flat spot in the power band. Those who gave me negatives don't know how it works. The ECM adjust the map by use of what is called a correction factor. It adjusts the entire map up and down in closed loop, and only by a limited degree within the parameters factored-in by the factory.

It's called EcmSpy

The ECM adjusts the entire map to suit atmospheric conditions...not intake and exhaust mods. That requires remapping or a race ECM if it's a compatible pipe.

the stock ecm will auto adjust to minor modifications. Gutting the stock exhaust will not require a new ecm. Just reset the tps to be sure :) |
