put some miles on it

[nunan0219]

hey guys,

ive been on the bike for about a week, put close to 500 miles on it so far.

gotta save, i love the ride. a lot more fun than i thought, coming from a cruiser i thought it was gunna be a pain in the ass and back to be honest. but i do have my questions.

i'm cheap, and computer literate/mechanically literate. I tuned my previous bike with a power commander, and just found out that techlusion manufactures a tuner for my bike.

my thing is, how accurate is the narrowband stock o2? i want to gut the muffler and make a dynomax or a flowmaster copy for my muffler, and i was told it has a k&n filter on it already.

Another thing, for a gutted muffler and k&n filter, would the race map for my bike be a suitable start? its an 05 xb9r

thanks again.

the narrow-band O2 does OK, replacing it every couple years helps it stay on edge

the race ECM does a great job with all kinds of systems stuck on the end, not perfect or anything but it helps work things out and it learns a little more aggressively

there is no wide-band O2 ECM for these bikes, nor do they really need one

so is the race ecm, just a stocker flashed with a race map?

one thing here. All the wideband 02 sensor is goin to give you is a more accurate and faster reading of your afr where as the narrow band, if you hooked it up to a gauge it would read say 15.1 and a few seconds later would read 14.6 and jump back and forth every couple seconds when it reads. Now with a wideband it is constantly monitoring your afr and will rapidly jump back and forth say 14.7 then reads 14.3 then 15.1 almost instantly. These numbers are just examples of course but you get the idea. This is why alot of tuners like to use the widebands.... they are more accurate because they are able to relay the information needed to tune faster than narrow band.

all i'm lookin to really do is jsut make sure the bike is running well, so i can rid it with the modded exhaust.

Get a ecm spy cable and download a race map

The narrowband is great if you are tuning for emissions! Otherwise if you are tuning for more power, smoother running motor, and rip your arms out of the socket torque a wideband is where its at! Do some searching and read up on here and you will learn everything there is to know about tuning these bikes. There are different methods available but I use a wideband to datalog then manually tune the fuel maps.
