hondata s300 sTrim
all b20-v s2p2 cams
on a cruise my afr reads in the 14.7 which is good.
and sometimes after a while i come to a stop or shift into neutral,
my Short Trim would be stuck at 1.56 and would not move at all.
and when this happens, my afr would read lean (high 16s and mid 17s AFR)
if i WOT, it will still be stuck at 1.56, but my afr would read 13.2ish area
i remember sTrim would be 0 if i WOT
so in order to get rid of the 1.56 number, i would have to shut engine off, and start it up again. then it would read back to normal.
is there any reason why it would do this?
and my Long trim would be 10, sometimes i see it at 15.....
and yes its tuned recently...please help
