Ok so when i would do a wot run my a/f would stay 12.5 to 13.0 and i thought that was a bit rich. Now i have pulled some more fuel out to get an a/f ratio of 13.0 to 13.7. Is that to lean? I'm posting a data log up with it. I think it's ok but just want to make sure i don't need to add a bit more fuel. I have tuned out all the knocks for wot but i still need to work on part throttle.
My setup:
k24a1
sri
megan mid pipe
no cat.
Thanks guys.

anyone?
I would let the engine get above 180-184 when dataloging.
Also with a SRI you will see some knocks come summer with a higher A/F like that around town.

So would it be better for me to get them in the 12.5-13.1 range?
Yeah that would be alot better, no sense in running lean. Add some fuel and try advancing the ignition a little bit to see if you can make a little more power that way.

I got all knocks out from 3k and up but i was knocking like crazy below 3k. Ill add some fuel and add a few degrees and see what happens.
I'm confused as to why it would knock in the summer...wouldn't it knock in the winter?Originally Posted by talonXracer
the inlet temps will be higher in the summer since the outside air is warmer. it will also lean out slightly in the winter since the colder air is more dense, so there is a chance for slight knocking in the winter as well. one thing to keep in mind with A/F is to remember that fuel also helps cool the motor. it is better to be safe than sorry. i would definatly agree with talonx, get it around the 12.5-13 range and you should be ok.
Yes I will agree safer is better, but boosted cars run low 12 a/fs.
with the SRI you pull in hot air, with an engine at operating temps in the summer this can cause preignition, aka knock. Knock can be caused by several factors,,too lean or too hot of cylinder temps. And with running a 13.7A/F at WOT on NA can cause those cylinder temps to really climb.

Well i put in a bit more fuel and this is how my data log sits. I have added 1% to the 13.0 area's and will do a pull and see what happens.
