I havent scanned the car in while, but I like to know some areas that I need tuning on, I think my 02s are way to high, and I have small kr issues, I'd like to raise timing but I knock, I not that great at tuning. basically I think my tune needs alot of work, and I confused on where to start.
his is my tune and my scan to view, thanks for help.

Just a few things I've noticed from your tune:
- MAF curve has a nice step in it and it is setup to read lower airflow than stock at high RPM's. Unless you know the MAF responds this way, I would recommend to bring it back to stock. As a side note, my MAF curve looks somewhat like yours when calibrated and I can't run 9 degrees at WOT without knock.
- You are commanding AFRs in the 10s when WOT. This is why your O2's are high. You could restore your base AFR to stock (12.4) or zero out your AFR vs TPS table. In the latter case though, I would also reduce the base to 11.5 to 11.7.
- You are currently running 15 degrees timing at WOT, and I would be pretty happy with that if it didn't knock. As a matter of fact, it looks like you have a similar issue as mine. I have similar mods except for a 3.4 pulley and I can't run anywhere near 15 degrees at WOT. So far though, I haven't figured out why.
I'll post my tune and log in a separate thread (so as to not hijack yours). If you could, please post the .hpl file as that is the scan log.
ya for some reason i coundnt upload the scan file out hpl, it keeps saving as a cfg file, if you know ho to switch it let me know and I will repost it

Try turning off injector skewing. Set them all to 100%, do a couple maf tunes to get your trims in line and then tune your wot 02's. I like to run a flat pe afr too. Makes it a lot easier to tune. You may also want to go back to stock timing and work up from there.

the only thing is I dont have the stock tuning tables for the timing, thanks for the help.

Download a bin from the repository for your car and just cut and paste.
