07 Attak Co2 adjustment

[saskattakman]

hey i have an 07 attak that i just installed the ulmer airbox mod on....sled runs great on mid and top....if i pin it from an idle it kinda bogs then takes off...if i hold it at around 3000 and pin it no problem....i tried adjusting the display to 10 for each cylinder...should i go more ??? i talked to ulmers and they said to try up to 20...will i need a fuel controller?? also if i add a aftermarket exhaust such as hauck will i need it??

Been there done that, but mine happened after installing the Excell exhaust. I tried the CO adjustment with no luck. I had to purchase a Powercommander III and make adjustments to the 2% and 5% throttle position between 1500 and 4000 RPM's.

 

[saskattakman]

what setting did you go up to on the display??

 

[Iceman57]

I went all the way up to; I think 25; 20 for sure.

Yup. Hopefully the maps you get will work. I just bought my own wide-band so i can take some of the guess work out, cause even with the maps that i got from other tuners my sled is still lean in some areas and maybe rich in other throttle positions. It is going to be a learning experience to say the least. Thank goodness for TY.

just wondering about spending 4-500 on an exhaust only to have to spend another 400 for a fuel controller just to make it work

FYI - There's a PC3 for sale in the classifieds

well i played with the co2 settings went all the way up to 25...sled ended up really running rough at idle...so i thought try -10...sled runs mint now no bog or hesitation...idles perfect...seems everybody is going up and few guys had to go down

We're always going down around here, specially the turbo sleds.
