I am trying to tune my MS1 set up as fuel only on my BBC. It is port injected, 60#/hr injectors, etc. As I look at the graphs from each run down the quarter, I am graphing RPM, AFR, and MAP. What I am seeing is that the AFR goes from around 12.3-12.5 in second gear to just under 12 (say 11.9) in high gear. Is this normal? What do you normally shoot for on AFR and where? I was thinking I could get the same AFR for the same MAP and RPM in all gears, but it looks like it is different.
Thanks,
Thanks,
