cold ride and missing at around 2500 rpm. xb12Ss?

[thumpinhard]

I got my ecm spy cable and with my new pipe it seemed to be lacking on the top end. I adjusted my 3 o2 sensor setting up just one digit..probably didn't make much of a difference but I was concerned that it might be running a tad lean.
I noticed especially when it was chilly last night that is kept missing with holding throttle around 22-2500 rpm.
Wondering if I need to richen up the middle setting more or what?
Any suggestions..I am new to ecm spy.
mine is an 06 xb 12Ss with airbox mod,pipe from randy hawkins,and race map.
Tnx!

Have you played with the fuel map at all? If you havent you probably are running lean. keep in mind that you can go all the way up to 255 in ecmspy.

I was told initially to raise the o2 sensor settings..not sure how to mess with the fuel map setting yet..or how much etc.

[thumpinhard]

how do you adjust the fuel map settings?
in the tutorial it doesnt really give enough info to feel comfortable screwing with it.
i was trying to figure out the right way to try and get the 2400 rpm setting at cruising throttle richer.
any suggestions for which areas to adjust and a good amount to raise it.

dang..i was hoping to get some specifics for what others have done for this problem..how much to raise etc. with ecm spy.
guess i will have to play with it slowly and hope i get it right eventually eh?

thats my plan. you can pay for some people to help you but keep in mind that several of the rows dont mean anything. rpms 0 and anything over 6000 really....I switch the TPS from 8bit to % bottom left corner. you change values by changing them right above the TPS option then hit =. At first keep the numbers close. I even went as far as to change the number I found in the tuning guide. Advice...dont use 255 on the rear cylinder. Other than that I check out the 3d views and try and built curves off that.

my bike is in pieces but i should be able to get it back together before next weekend.

[thumpinhard]

Thanks..I will see if I can find the 3d views and will play with the tps values as mentioned.
hope it goes easy for ya getting er back together.

Got it back together. Ran like a champ and then something in the starter went bad...had any problems like that?

[thumpinhard]

update..i did a lot of adjusting..much improved..but still does not have the immediate power off the bottom that it should have with the hawkins modded pipe.
it still has a bit of missing around 2500 rpm when cruising..especially when cold outside.
