Hey all,
I have been trying to get the idle tuned up. It's an LS7 with a mild cam (11 degrees of overlap), worked and milled heads (11.8 SCR), I/H. The idle speed and manners are right where I want them, but I can't get the AFRs to stay steady thru warmup. Right now starts fine and AFR follow commanded, but gradually gets richer. I can bring the VVE higher to match the warmed up AFR in the idle area, but them it will start too lean. Any help would be nice.
Here... COS in progress_0008.tun Log_0094.efi
Thanks.
