What are your O2's at WOT?

don't remember, I'll check today.

o2s are cycling. I just gave you the peak number.

ok, o2s at WOT:

2nd gear, front and rear were around 82-86. I think thats kind of rich, isn't it? cuz stoich is like 45-50.

For WOT, that's very lean. You want more like .90-.92 at WOT. Stoich at WOT results in lots of knock and then internal engine parts appearing outside the engine. You only want stoich (or roughly around stoich) during idle and light cruise.

oh, thanks for the info. I didn't know that. always learning...

so thats lean? thats nice to know. I don't know how much i have when idling of cruising cuz its always cycles.

get a wideband.

you dont want to guess on your tune. your injectors are too small or the fuel pump cant keep up.

a2j · 02-06-2008, 06:16 PM

thats exactly what I want to do.

and for right now I'm taking it easy. its cold out there.

a2j · 02-08-2008, 04:39 PM

alright... today I tried WOT with regular (93) gas and I had 96 o2s. so I guess 86 is lean and I need bigger injectors for e85.

ver fer · 02-08-2008, 09:55 PM

Ah yeah!
