tried to really dial in my tune last night doing WOT blasts in 3rd loging and adjusting the PE vs rpm. i was able to get a more even ratio and am able to prety easily minipulate the a/f ratio in 3rd but look what it does in the first 2 gears <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> , any ides on why it is much leaner in 1st, and a little leaner in 2nd?
the only off the wall idea i can come up with is i have 50lb injectors and never adjusted the offset table. i had to tell the computer the injectors were smaller then they are to get the ltrims right. i really dont think this would be the problem though because the computer prety much asks for the same pulsewidth for the entire run. somewhere in the 16ms range.
