1st log , how does it look

[black12]

log is from a launch at 5000. i am pushing 15 psi on b16g with 650's, 255, uicp, hks ssqv
o2 external dump, 2.5 cat-back, test pipe ,intake ,hacked maf

Way too many numbers. Just log rpm, front o2, knock and timing. Only log from 3k to redline and keep it floored the whole time.

 

[black12]

ok here is my second log. this was from 3k rpm in second gear

 

[olmytsi]

Can you log the tps next time cause its hard to see when you let off. Did you let off where the o2s are in the single digits? If not then you are running really lean there and you need to richen it up. Up to 6k, it looks pretty good, and then the 02s start going lean

 

[black12]

no i didnt let off. how do i richen it up,just add more fuel. i run dsmlink btw.

 

[olmytsi]

Yeah just add fuel little by little. I believe ideal o2s for a 1g is .88 but im not positive so hopefully someone else can chime in. Jus richen it up so all your o2s are in the .88 range and see how she runs. Basically, you want to reduce your knock count as much as possible. It rises up top so richen it up there and log again and make changes, then log again until knock is as low as possible.

ok i richend it up and heres wat i cam up wit after like 20 pulls

 

[olmytsi]

Ok, looks like the top end improved some. If you look at your log, the rpms seem to drop and go back up, whats up with that? You didnt mention a fmic. Back to back pulls heats up your intercooler and affects performance so let her cool down in between pulls. Does the car pull better now? You need to richen it up some more and see what happens. Also, you are getting ALOT of timing, what are you using to tune? If its an afc, what percentage values are you at right now?

 

[black12]

i use dsmlink v2 to tune. i do notice the rpms dropping and coming back up. im not quite sure why its doing that. i kinda feel like my top end has more power but it could be just in my head. but i do feel like i lost some low end. im gonna do a few more pulls tonite when its cooler and ill try taking out some timing. thanks for helping

 

[black12]

i took some timing and this is what i came up with.also what would happen if i add timing in the lower rpms

 

[olmytsi]

I wish i had dsmlink. I knew your timing was too high, that was the cause of your knock up top. You should shoot for 20 maximum advance up top. Does the car pull better now? I have no idea wat more timing down low will do. 2 degrees of knock is not bad but you can keep making changes til you get it right. Glad i can help.

 

[black12]

im still not sure if i can tell a difference in the performance. sometimes i do and sometimes i dont feel like it pulls better. im gonna try to turn up the boost a little 2moro and post another log.

 

[black12]

well i did a log last nite .this time the car was completely cooled off. and im positive i felt a gain this time and there was no knock,well the most i got was .7. i guess its time for a fmic or some other type of cooling method. thanks for the help. and i highly recommend
dsmlink. im startin to get the hang of it
