Yes, I'm trying to see where it is coming from... but I don't see it.

I don't either:( I got my fuel pump installed today, and I should have wiring done by tomor or wed. I will keep yall posted.

Okay, for the log named: throttle cracker disabled, still cruise control with throttle closed.efi , you start having shenanigans after you stall out in frame 1720. I don't know hwy but I thought I'd point it out as something significant. it goes from 12 ish g/s to 21ish g/s.

Also, are you running AC?

I am still running A/C and do you think for some reason my engine start up extra air flow is randomly being put back into my tune?

Seems like it to me, but I think I'm in over my head here. I went through your whole tune last night and can't find it. With the exception of populating all your p/n tables, I'm not sure what else if could be.

I found the issue, the desired airflow tables in park based on IAT were causing this issue. I have since fixed it and all is well. What timing adjustments should I make to make the car more snappy? I don't want detonation but I want to add throttle response.

Should I just add 2 or 3 degrees of timing for low load and between 1200-2200 RPM and run CALCVET and see where I have knock retard and then make the necessary adjustments?

Can you show a before/after (screenshot)...?

Yes, do this.

Nevermind It did not fix it:(((((((((( For some reason sometimes it does it and sometimes it does not. It is very strange, I just took a couple logs trying to fix("check it out" was my most recent and I would start with this one) and will include the tune. It is not coming from throttle cracker/follower, or due to A/C, or due to startup compensation added airflow. ANY other ideas are greatly appreciated as the car drives great except when it does this.
thanks guy!

it also seems to be running lean for the weird case when it has 20+ g/s of air at 0% throttle

[joecar]

If you look at SPARKADV and TP, you will see as TP goes between 0.4% and 0.8% that SPARKADV jumps up/down by large amount.

My problem is that randomly my engine will add 7-8g/s of air to my idle airflow.

Learn what the tables do before you make adjustments... don't mess with tables that you don't understand. Try the attached tune file.

That's because your tune isn't very good... start by re-tuning your MAF and VE tables.
