Alot of cobalt guys have been having problems with there IDC's doubling and this cause's the afr to go in the toilet. I'm posting a couple logs of this problem. One is in speed density (where there is no problem). The next is with the maf enabled on the same tune (IDC double's at WOT). I'm not sure exactly what table we need, but one thing I've noticed is that the biggest spike is always at 9900hz. Lets see what you guys can come up with.
