I'm currently trying to learn how to road tune fuel trim. Here is my set up:
ITR head
IPS K2 cams
RBC i/m
ITR t/b
Karcepts CAI
Prototype velocity stack
k24 block
TSX rods and pistons
Hytech 4-2-1 header
3" exhaust
I started to practice on the low cam at 0 degrees. 13:1 a/f ratio is what I was shooting for. I was able to get the fuel curve pretty flat. However, while I was tuning I noticed that at 5000 rpm and WOT (-0.2/psi) I had to go as high as 2840 units of fuel to get the a/f ratio I wanted in that area. Is this normal? Also, is 13:1 a/f ratio too rich to be shooting for? Thanks.
