Even engine is a little different. There is a lot about CO settings in the mountain sections and it seems like evaluation plays a role too.

I have a mbrp exhaust and I am at -20, before I changed CO it fell on its face.

is this for just the slip on?

Yes it is just the slip on, I see you have a mbrp. I do a lot of friendly drag racing and right after I changed the exhaust I was neck and neck with a sabre cat 700. That was terrible, so I changed the CO settings at home quite a few times looking at the plugs and now I put the little kitty to bed

by adding or removing fuel? how long does this procedure take from beer one on? Heard you have to have 18" of wire??

I took a piece of wire from the ground on battery to an alligator clip on the other side to the white wire in the nose cone. You have to cut the tape away but in the nose there is a whole gob of wires with one sticking out that has a plug in it. Take the plug out and hook up the alligator clip to the prong. Once that is done make sure key is off, now hold both buttons down on speedometer and then turn the key on while still holding the butttons down. Then you will see a DIA message come up. Navigate through them until you see CO, you will have to change each cylinder separately. C1, C2, C3 I had to go to -20, but from what I have read each sled is different. CHECK YOUR PLUGS!!!! You don't want to blow it up. But I kept that wire hooked up until I had it tuned in. There is better directions in the mountain section.

i have excell header and exhaust, i have my co at +10. trying to get away from that low to mid exhaust burp sound. you guys at -10 to -20 with aftermarket exhaust are you having the burple sound off and back on throttle at mid range throttle.

I did 160 miles on the weekend and with the filters and exhaust i never noticed any more hesitation than it already had before, the midrange is very nice and she sounds lovely too. I will check to see what the CO settings are as i have not touched them yet. What exactly is the CO level adjusting the air fuel? I dont want to run her lean but i also dont want to check the plugs every time i mess with the setting. Time for an LM1 tuning session hmmmm.
