p28 a/f ratio

Post by the_crazy_russian » Sat Apr 01, 2006 10:02 pm

hi,
was wondering if someone could tell me what the base p28 calabration a/f ratio is at wot and idle?
my a/f at idle is around 20:1 . at wot it is 14.9:1 until 4000rpm then it's in the low 13's. this seems lean to me, but I just want to check to make sure the base map isn't suppossed to run this lean before I start digin around to find out why.
Thanks,
B

uh, thats very lean, at idle you should be around 14:7 and wot around 12.5 if your boosting around 11.7. get it tuned before WOT or else......

naw not boosting yet. just running the plain base map. I was trying to figure out if it was the base map or an engine problem that is making it run lean. but sounds like it's an engine problem.it's a new motor and swaps usually have some bugs. time to go back and check the timing again ect.

Thanks for your info,

B
