Please check my idle tune Hi,
Can you please check my tune and let me know if theres any major things you guys see ? id like to start logging and building my VE table. I just wanted to be sure I didnt have any red flags on my settings so far that could end up causing me to chase my tail.
I was struggling with getting the idle to actually stay. It use to chase and die out. Found out about "false lean" on idle and after dropping my ve on idle by 20% the idle actually held better. See log. Id say im closer to 1.2 lambda instead of 1.
I also changed the follower delay to 2 sec for now to help manage it(though I will drop this later when its fined tune)
I bumped up idle to 950 and that seems to help a bit more. But im thinking maybe once I have it more fined tuned i can drop this down?
2000 pcm-LQ4, ss2 cam
3 bar map, e85 210lbs injector-Im using ID2000 for injector data. 43psi boost reference regulator with a return style rail.
Thank you for your time

Check your MAP sensor offset. It doesn't look correct. Get the number off the map sensor and look it up or post it and someone will have the correct number.
That cam should idle around 850 or so easily.
Since you are running SD, the VE table needs to be correct. Just pulling 20% is not going to get you running like you want. If you are going to run open loop all the time, you can run idle leaner, but if you plan on going back to closed loop, you will be retuning.
Your Base running airflow looks high. At idle, Dynamic air is about 11 to 13 gsec, you are at 17.80 in your idle airfow table. try reducing this to somewhere around 12 or 13 and smooth it out going back to the cooler temps.
Your fuel table is set up for a boost referenced return system. is this what you have? and are you running 43# or 58#, and does your injector data reflect the correct fuel pressure?
