Hey i just found out i forgot to reconnect the MAP sensor wires from my V-AFC.. so thats why my car was bogging like crazy when i tried to go and thats why it was throwing a MAP sensor code... well i fixed the problem and now i'm running -30% across the board and she idles almost perfect now and no CEL that i know of yet... there shouldn't be one with a RHB5 at 8 psi. well anyway just wanted to know if -30% across the board is wayyy to rich or what. i tried -40% but it seemed to idle weird..

one setting across the board isnt going to be good, youll need to adjust for each RPM segment. so if idle works at -40 youll run lean at3000 PSI.. so you have to think of this logically

 

i'm at -30% across.. thats enough fuel to supply across the power band.. but yeah i'll lean out the idle and the lower rpms. but its someplace to start

 

..or just read the Engine Management FAQ, section 2, question 4?
