t25, dave brode uip, 1G bov, rsr downpipe no cat, rsr catback, no boost control. 16psi. 12psi at redline.

what do you guys think of the log? Sorry I couldn't get all the way up there. Worried about cops 3rd gear pull.

Looks like my timing sux

Yours isnt bad.

If you logged to 6500 im sure you would see it go to 18

You may want to log throttle as well because when the ecu sees an increase in air (ie increase in throttle) it will pull timing. If your air flow is held steady than it looks like you may be knocking at about 3500 rpm.

I have very similar mods as you except I have an S-AFC. I can lean it out alot at the high rpms because the turbo cant hold 15 psi of boost after 5500 rpm.

My settings right now are

high
1k to 4k
-3

4.5k to 5.5k
-5

6k up
-8

This gives timing curve of 4 to 7 at tip in up to 21 deg at 6700 rpm. It pulls so much harder just by leaning it out. Even on the stock injectors and turbo.

your log looks pretty good...i also agree you might have a slight knock at 3600.....other than that your running a little rich......on pump gas .90-.92 volts is kinda where you wanna be..good luck

 

[truwarrior]

I think I'm running kinda lean up top. Isn't .90 to lean for a 2G? I'm gonna have to get a BC and makw a run at 15 psi.

 

[NJR Racing]

.90 is the border line for pump gas....even though some people have run leaner but i would draw line at .90.......if you want to be real safe tune for .92 up top but you should lean out the mid range....96 is kinda rich...if you can get .92 across the board you should have a pretty good tune....just make sure no timing is getting yanked.....

 

[theTuner]

yo NJR racing, when you say timing geting yanked.. how muc? i see 17-19 drops all the time but it seems ok

 

[NJR Racing]

when i say yanked i mean getting pulled out or taken away......on a 2g try to tune for .92 across the rpm band and try to get timing to at least 18 at redline.........18-22 degrees of timing at redline is pretty good.....
when i look at your log timing is 8 at 2445 then drops to 4 until 3187 then it 7 then drops to 6 at 3699.......your timing should always increase..if it decreases your probably getting knock...in the midrange your o2 is .96.....get it all to .92 and your timing should be good....good luck.....i just notice you have no afc....its pretty hard to tune without it....so i guess you cant change anything until you get one......
