Well I got my wideband o2 put in this morning along with a resonator so I could hear the s/c better lol.
I bought the plx R-500 wideband kit that I like VERY much. I would recommend it to anybody. Little pricey but oh well. Anyways on to the important stuff.....................
So at idle my a/f goes from 14.2-15.3.
At WOT I'm seein high 13's to low 14's a/f without the alky kit on.
When I turn the alky kit on and give it gas......as soon as the alky kit turns on my a/f drops all the way down to the 10's lol, BUT that is at only half throttle.
At WOT with the alky kit on I see low 13's to mid 13's all the way through the rpms.........
I also have a knock sensor input on the Wideband computer screen that shows no knock whatsoever........
What do you guys think of these numbers??? Any input would be great
I say its track time now and also time for me to put the 2.6 pulley on!

Your idle AFR is perfect. Because you should still be running at stoich when in vacum. At WOT without the alky kit on, I'd try for low 12's. Parital throttle is really hard to tune for and it takes lots of screwing around to get it right. But your end goal should be mid to high 11s with the alky kit on at WOT.

yeah mid to low 12's is perfect a/f's from what I have seen on our cars.. 11's I was getting the p0172 code

mine runs high 13's to hig 15's at idle
under wide open i see mid to low 13's
and with the water injection(with methanol) my a/f drops a few tenths , its never gone richer than about a 12.8
I wouldn't even consider throwing that pulley on until you get your A/F into the mid 12s during boost.
Low to mid 13s is not good if you're going to be putting on more boost.

what size water injection nozzle you got? a m2?
nice to know what the a/f ratios are.
thanks.
Yea I'll address the a/f tomorro after work.....I'm actually happy with the 2.7 right now just need to work on the a/f...........
Jake- I'm not exactly sure what nozzle it is...I'll look tomorrow but I THINK its a M2.

mid 14s is still high for boost. partial throttle is really difficult to tune for, but if you aren't seeing a lot of boost while naturally cruising, you should be ok

^ yea when I said crusing I meant just driving and not boosting....
