Target afr numbers
Good afternoon,
working on a blown 555 with Holley terminator efi and I need suggestions on target afr numbers idle seems to like 13.7 at 850rpm whats a good number for 3500 -2 psi vacuum and up? can you read a new plug at partial throttle? |
What size is the boat, I'm guessing 12.0 to 12.3 under low boost, 11.9 at higher boost. Rich is safer than lean.
